Diagram 4: Block schematic diagram for the Pulse
As you can see, the Pulse consists of two different types of components for sound
generation and sound shaping:
• Oscillators, mixer, filter, VCA.
Sound generation actually occurs within the oscillators. They produce square,
sawtooth and triangular waveshapes. The mixer follows the oscillators in the signal
chain, which is where the oscillators' output signals are mixed. Pink noise can also
be added to the mix. The filter then shapes the sound by amplifying (boosting) or
attenuating (dampening) certain frequencies. The VCA is located at the end of the
signal chain. It is an amplifier that determines the overall volume and position of
the signal within the stereo panorama.
• Modulators: LFOs, Modulation Matrix, Envelopes.
The modulators are designed to manipulate or modulate the sound generating
components to add dynamics to sounds. The low-frequency oscillators (LFOs) are
designed for periodic or recurring waveshapes and envelopes for modulations that
occur once within a given time frame. These generators are assigned to parameters
via the modulation matrix and influence these parameters to alter a sound.
Available modulations include pitch, waveshape, volume, filter settings, etc.

On the Pulse Plus, you can feed in an additional audio signal.
User’s Manual Pulse • PulsePlus

8.2 Oscillators
Oscillators are the heart of every synthesizer. They produce the sound that is later shaped
by the filter and other components. The Waldorf Pulse is equipped with three oscillators,
each of which has different features.
Semitone / Tune
Oscillator 1
Shape / PW
OSC1
Oscillator 1 delivers a periodic oscillation where you can determine waveshape and
frequency. The frequency is defined by the pitch of the notes that are sent via MIDI.
Maximum pitch is approx. 8,5 kHz. The following parameters are available:
Semitone
-48...+48
Determines the pitch of the oscillator in semitone
steps.
Tune
-32...+31
Fine-tunes the oscillator in increments of 64ths of a
semitone.
Shape
Determines the type of waveshape to be generated.
The following waveshapes are available:
Pulse: square with variable
pulsewidth
Sawtooth
Triangle
PW
0...127
Determines the pulsewidth of the square wave. If you
select a waveshape other than pulse, than this
parameter has no influence on that waveshape.
PW stands for pulsewidth. If you select a square waveshape, you can determine its
pulsewidth. The value 0 is equivalent to a pulse ratio of 1%, the value 127 is
equivalent to 50%.
PW=0
PW=127

Oscillator 2
Similar to Oscillator 1, the second oscillator produces oscillations with variable
waveshapes and frequencies. Available parameter settings are identical to those of
Oscillator 1, with several additional options.
Semitone
-48...+48
Determines the pitch of the oscillator in semitone
steps.
Tune
-32...+31
Fine-tunes the oscillator in increments of 64ths of a
semitone.
Shape
Determines the type of waveshape to be generated.
The following waveshapes are available:
Pulse: square with variable
pulsewidth
Sawtooth
Triangle
Crossmodulation
Crossmodulation is a XOR combination of the square waveshapes of
Oscillators 2 and 3:
Oscillator 2
Oscillator 3
Crossmodulation
Diagram 6: Crossmodulation
It produces a waveshape that contains the sum of as well as the
difference between the two original waveshapes.
User’s Manual Pulse • PulsePlus
21
�
Although Oscillator 3's square waveshape is used for crossmodulation, it does not
mean that this square waveshape must be used as the source signal. Because the
crossmodulation is purely internal, you can select another waveshape for Oscillator 3
if you so desire. Please note that you can also modulate Oscillator 2's pulsewidth at
any time. Additionally, you can switch synchronization on and off independently.
PW
0...127
Determines the pulsewidth of the square wave. If you
select a waveshape other than pulse, than this
parameter has no influence on that waveshape.
Sync
Switches synchronization with Oscillator 3 on and off.
Synchronization on
Synchronization off
When the oscillators are in sync, Oscillator 2 is the slave and
Oscillator 3 is the master, i.e. Oscillator 3 controls its counterpart.
At each new periodic cycle of the master oscillator, the waveshape of
the slave oscillator is also started, which leads to interesting effects.
These are especially evident when the two oscillators are operating at
different frequencies.
Oscillator 3
Oscillator 2
in Sync
�
Diagram 7: Oscillator Synchronisation
Synchronization is possible with all of Oscillator 2's waveshapes. You can also freely
select the waveshape for Oscillator 3.
Keytrack
Determines if the pitch of the oscillator is dependent on the MIDI note
number.
Pitch changes in proportion to the
incoming MIDI notes
The pitch remains at the value you
entered for "Semitone" and "Tune",
regardless of the note you play.

Oscillator 3
Shape
OSC3
Similar to Oscillators 1 and 2, the third oscillator produces oscillations with variable
waveshapes and frequencies. However, it does not feature variable pulsewidth. The
oscillator's highest frequency lies an octave lower than that of Oscillators 1 and 2, at
approx. 4,25kHz.
Semitone
-48...+48
Determines the pitch of the oscillator in semitone
steps.
Tune
-32...+31
Fine-tunes the oscillator in increments of 64ths of a
semitone.
Shape
Determines the type of waveshape to be generated.
The following waveshapes are available:
Pulse: square
Sawtooth

Noise Generator
In addition to the oscillators, a noise generator that produces pink noise is available. The
noise generator has just one parameter: volume. Volume is determined via the mixer.

Volume of the external audio signal
The mixer's output sends the signal to the filter's input. The Pulse is designed to enable you
to overdrive this signal. Saturation occurs at the following values:
• If you program a sound using just one oscillator, then the signal is overdriven
somewhere in the volume value range of 40.
�
24
• If you use more than one oscillator, a volume value of approx. 30 is the overdrive
threshold for each oscillator.
The option of overdriving the signal vastly enhances the variety of sounds the Pulse
can produce. The Pulse is an analog device, so we can't give you a precise value
when a signal will be overdriven. As the volume increases, the signal becomes
slightly saturated and flows seamlessly into total disortion.
An overdriven signal has a richer sound, as overtones are added to the clean signal.
This is especially interesting in conjunction with sawtooth and triangular waveshapes,
as square waveshapes are inherently very similar in structure to other overdriven
waveshapes.
Distortion is most audible when you drastically detune several oscillators in relation
to each other, especially over a range of several octaves. This effect is even more
interesting when you tune the pitch of one oscillator a semitone or several semitones
above or below the true octave.
User’s Manual Pulse • PulsePlus
8.4 Low-frequency Oscillators (LFOs)
LFO1 Speed / Shape
LFO2 Speed / Delay
In addition to the main oscillators, the Pulse is equipped with two low-frequency oscillators
which are also used for modulation purposes. The acronym "LFO" has become the standard
term for low-frequency oscillators.
LFO 1
Similar to the oscillators, the first LFO generates periodic waveshapes with variable
frequency and waveshape. These are determined by the following parameters:
LFO1 Speed 0...127
Determines the frequency. A value of 0 is equivalent to
0.0008 Hz, i.e. one cycle in two minutes. A value of
127 is equivalent to 261.6 Hz, i.e. the frequency of the
middle C on a MIDI keyboard (C3). Within the value
range of 16 to 127, the LFO is scaled in semitone
increments. For instance the value 115 is equivalent to
130.8 Hz or C2. 10 is equivalent to G1 or 98 Hz.
If you use a MIDI Sync Mode via the LFO1 Shape parameter, you
can determine the LFO speed by the note length in a range from thirtysecond notes to 8 bars. Also dotted values are availiable. As long as
the arpeggiator is active, the LFO will synchronise to the internal
clock. However, if the arpeggiator itself is in MIDI Sync, the LFO uses
the external clock too.
Example: 1/4
Example: 1/8 dotted
Example: 2 bars
LFO1 Shape Determines the type of waveshape to be generated.
Sine

Sawtooth
User’s Manual Pulse • PulsePlus
25
Pulse
Sample & Hold
�
Sample & Hold samples a random value and holds it until the next
LFO cycle begins. If LFO1 Speed has a value of 0, then a random
value is generated for each new incoming MIDI note.
You can modulate the frequency of LFO 1 while you are playing. For instance, you
can use the modulation sources Keytrack and Pitch Follow to change the pitch of the
current note via the LFO, just as you would for an oscillator.
For the waveshapes triangle, sawtooth and pulse there is an additional
MIDI Sync Mode, which is used to synchronise the LFO speed to MIDI
Clock. Therefore the LFO can follow a given song tempo and all
tempo changes are recognised, too.

Sawtooth with Clock:
Pulse with Clock:

26
Please read the paragraph about the parameter LFO1 Speed. You’ll get
some additional information there.
When MIDI Sync is used for the LFO, the speed can not be modulated via the
modulation matrix.
User’s Manual Pulse • PulsePlus
LFO 2
The second LFO also generates periodic waveshapes with variable frequency. However, the
waveshape is not variable; it is always a triangular wave. As an added feature, this oscillator
is equipped with a variable startup delay function.
LFO2 Speed 0...127
LFO2 Delay
1...127
Determines the frequency. A value of 0 is equivalent to
0.0008 Hz, i.e. one cycle in two minutes. A value of
127 is equivalent to 261.6 Hz, the frequency of the
middle C on a MIDI keyboard (C3). In the value range
of 16 to 127, the LFO is scaled in semitone
increments. For instance the value 115 is equivalent to
130.8 Hz or C2. 10 is equivalent to G1 or 98 Hz.
Delays the start of oscillation from 2 milliseconds to
one minute after an incoming MIDI note has been
received.
Delay off
�
The amount delay before oscillation sets in depends on the parameter setting for Env
1 Trigger Mode; in other words, the trigger mode of the filter envelope. In the two
Single Trigger modes, LFO 2 oscillation is not delayed at all when you play legato
notes. Use this effect for typical keyboard solos.
User’s Manual Pulse • PulsePlus

8.5 Envelopes
The Pulse's envelopes allow you to manipulate the sound parameters via rate or timed
modulations. These envelopes feature ADSR characteristics.
�
Most analog synthesizers feature ADSR envelopes. These envelopes are made up of
four parameters that determine their response: Attack, Decay, Sustain and Release.
The following diagrams illustrate the structure of an ADSR envelope:
Depth
Key pressed
Key released
100%
Sustain
Attack
Decay
Release
Time
Diagram 8: Structure of an ADSR envelope
The envelope is started by pressing a key. It ascends to its maximum value at the rate
determined by the Attack parameter. It then descends at the rate determined by the
Decay value until it reaches the predetermined Sustain value. It remains at this value
until the key is released. The envelope then descends to zero at the rate determined
by the Release parameter.
Envelope 1
Attack
Decay
Sustain
Release
Keytrack
Trigger
ENV1/2
The first envelope is designed to control the filter (VCF) but can also be used for other
modulations. The following parameters determine the envelope's response.
28
Attack
0...127
Determines the attack rate or amount of time it takes
for a signal's volume to go from zero to maximum
level. A value of 0 is equivalent to less than two
milliseconds and 127 is equivalent to approx. 1 minute.
Decay
0...127
Determines the decay rate or amount of time it takes
for a signal to reach the sustain phase. The values are
the same as for attack. Note that Sustain values near
zero reduce the duration of this phase.
Sustain
0...127
Determines the sustain level which is held until a note
ends.
Release
0...127
Once the note has ended, the release phase begins.
During this phase, the envelope fades to zero at the
rate determined by the release value. The values are
the same as for attack. Note that a sustain value other
than zero reduces the length of this phase.

has on the duration of all phases. The duration of
phases is not influenced when this value is 0. Positive
values have the following effect: all notes higher than
E4 (note number 64) increase the duration of the
phases proportionally; the notes lower than E4
decrease the duration of the phases. For negative
values, notes lower than E4 than produce longer
envelopes.
Trigger
Four different types of triggers determine how and when an envelope
is started.
Single Trigger 1:
The first note starts the envelope. All
other notes do not restart while a note
is sustained. The release phase is not
started until all keys are released.
Single Trigger 2:
Essentially the same as Single Trigger 1,
except that the envelope is started at
the current value rather than reset to
zero at every new start.
Retrigger 1:
The envelope is restarted with every
incoming note.
Retrigger 2:
The envelope is restarted with every
incoming note, but is not reset to zero.
Envelope 2
The second envelope is designed to control the volume (VCA), but can also used for other
modulations.
Its parameters are identical to those of Envelope 1.

8.6 Modulations
Select

Amount
Destination
MOD
In this context, modulation can be described as the following process: A modulation source
influences a modulation destination. The extent of the modulation, i.e. the amount, is
variable. Both the source and amount of the modulation can have positive and negative
values. If both values are negative, then the modulation is positive just as the product of
two negative numbers is positive when they are multiplied.
The Pulse features different types of modulations:
• Four modulation chains with freely assignable sources, amounts and destinations.
The modulation matrix consist of these types of modulations.
• Two modulations with fixed destination: Pitch and Cutoff.
• Additionally, there are several common modulations with fixed destinations and
fixed sources, e.g. Note Number (Keytrack) modulates the envelope rate and
Envelope 1 modulates the cutoff frequency.
Modulation Matrix
The four freely-assignable modulation units offer the most unusual options. These are edited
in the MOD group of Parameter Level 4.

Amount
-64...+63
Determines the amount of modulation in a value range
of -64 to +63.
The intensity of the modulation Amount depends on the type of modulation source
you select:
• For the so-called unipolar modulation sources Env1, Env2, Modwheel, Aftertouch,
Velocity, Breath Control and Control X, the modulation amount lies within the
range of 0...1.
• For the so-called bipolar modulation sources LFOs, Keytrack and Pitch Follow, the
modulation amount lies within the range of -1...0...+1. Please note that the linked
modulation sources LFO1*Modwheel, LFO1*Aftertouch and LFO2*Env1 are also
bipolar modulation sources.
• For the modulation sources Keytrack and Pitch Follow, a value of +45 represents
100% of the scale.

Routing a Modulation Source to CV 2 Out

On the Pulse Plus, one of the 16 modulation sources can be routed to the CV 2 Out jack
with variable amount. In this case, the control voltage is treated as a kind of destination in
the modulation matrix.
☞
This is how you route a modulation source to CV 2 Out:
• Choose the modulation unit for the control voltage by means of the Select
parameter:
Control Voltage CV 2
• Adjust the values for the source and the amount parameters in the same way as it’s
done at the other modulation assignments.
34
User’s Manual Pulse • PulsePlus
Pitch Modulation
In addition to the modulation matrix, Pitch Modulation is available as a fixed assignment.
This gives you another modulation option without having to assign a matrix path.
Pitch Mod
-64...+63
Determines the amount of modulation.
Source
S.00...S.15
Determines the modulation source. Sources are
assigned in the same manner as in the matrix.
Pitchbend
Most MIDI keyboards are equipped with a device that allows you to alter the pitch. These
are capable of sending MIDI Pitchbend messages and are usually called pitch wheels or
pitch benders.
In the Pulse, Pitchbend messages can be used to modulate the pitch for all oscillators.
Pitchbend Scale
0...24
Determines the intensity of the pitchbend in semitones
via the Pitchbend messages.
Portamento
Portamento is a continuous gliding from one note to another as some string and brass
instruments are capable of (e.g. trombone). The following two parameters are used to
determine the type of portamento the Pulse can produce.
Portamento
1...127
Determines the duration of a glide.
Portamento off
Mode
This parameter determines the type of portamento.
normal: portamento from the previous
note to the next.

8.7 Filter
Cutoff / Keytrack
Env1 Sens / Velo Sens
Cutoff Mod / Source
Resonance
VCF
Once the audio signal leaves the mixer, it is sent to a variable analog low-pass filter. This
filter is a component that has significant influence on the Waldorf Pulse's sound
characteristics.
�
A low-pass filter dampens frequencies that lie above a defined cutoff frequency.
Frequencies below this threshold are hardly affected. The frequency range below the
cutoff frequency is called the band-pass range, the frequencies above are called the
stop-band range. The Pulse's filter dampens stop-band frequencies by 24dB per
octave. This means that the volume of a frequency that lies an octave above the cutoff
frequency will be 24dB less than those frequencies of the signal that fall into the
band-pass range. To give you an idea of the extent of dampening, consider this: A
reduction of 24 dB reduces the original volume by approx. 94%. The dampening
factor two octaves above the cutoff frequencies reduces the original volume by more
than 99%, which in most cases means this portion of the signal is no longer audible.
The Pulse's low-pass filter also features a resonance parameter. Resonance in this
context means that a narrow frequency band around the cutoff frequency is
amplified. If this frequency is amplified to a great extent, then the filter will begin
self-oscillation, i.e. the filter oscillates audibly even when it does not receive an
incoming signal.
The parameters of the Pulse filter:
36
Cutoff
0...127
Determines the cutoff frequency. Tuning is scaled
roughly in semitone steps. At a value of 57 and a
Keytrack value of 32, the filter cutoff frequency is equal
to the pitch of a given MIDI note. If the tuning is not
scaled correctly, please refer to the chapter about the
filter tune function.
Keytrack
-64...+63
Allows the filter cutoff frequency to be influenced by
the MIDI note number. Negative values reduce the
cutoff frequency, positive values increase it. A value of
+32 is a equivalent to a ratio of 1:1, i.e. the filter cutoff
frequency changes by an octave for every octave
interval you play. A value of +63 is equivalent to a
change of 200%, all other values change
proportionally, e.g. +16 equals 50%, -32 equals -100%
etc.
Env1 Sens
-64...+63
Determines the amount of influence the modulation
source Envelope 1 has on the cutoff frequency.
Velo Sens
-64...+63
Determines the amount of influence Envelope 1 has on
the filter cutoff frequency based on key velocity.
Cutoff Mod

8.8 VCA
Volume / Velo Sens
Panning
VCA
The final component in the Pulse's signal chain is the VCA (voltage-controlled amplifier)
The VCA determines master volume and the stereo position. The signal is then sent to the
two outputs, where you can patch it to other devices.
An important factor in understanding how the VCA works is the fact that Envelope 2 is
always the volume modulation source. Consequently, if Envelope 2 is closed, the Pulse
cannot deliver an output signal.
The VCA is a stereo component, so you can determine the position of the signal within the
stereo panorama. You also have the option of a panaroma modulation. For this purpose,
you must define the modulation in the modulation matrix.
The parameters:
Volume

9. MIDI Control
This chapter describes the options you have available to control the Pulse via MIDI.
�
You will find a glossary at the end of the manual. It explains the various terms used
herein. If you have any questions about MIDI and MIDI messages, consult the
glossary.
9.1 Calling Programs via Program Change
All of the Pulse's sound programs can be called via MIDI Program Change messages. As the
device contains 100 program locations, it recognizes program numbers 1...100.
Program number 100 is a random program.
�
The Pulse has a special feature: A sound is not interrupted during program changes.
This feature can be used creatively. Please note that a program change takes approx.
40ms.
9.2 Influencing Sounds via Control Change Messages
There are two ways MIDI Controllers influence sounds:
• Controllers can be used as modulation sources.
• Controllers can change sound parameters directly.
Controllers as Modulation Sources
The Controllers Modwheel and Breath Control are always used as modulation sources. The
freely definable Control X function can also be used as a modulation source. The X stands
for a globally defined Controller number 1...127. The following parameters are suitable for
this application:
Cutoff Mod Source, Pitch Mod Source, Mod Unit 1...4 Source
Changing Sound Parameters
Every parameter is assigned a Controller number through which the parameter can be
changed. If a parameter is changed at the device, then this change is sent along with the
appropriate Controller number via MIDI. This is especially helpful when you want to record
changes you made at the Pulse to a sequencer.
All controller messages are sent and received via the channel defined in the MIDI Channel
parameter. The appendix of this manual contains a table listing the Controller numbers and
the sound parameters they are assigned to.
9.3 Pitchbending
The Pitchbend Scale lets you define to what extent a pitchbend message influences the
pitch of the Pulse. Pitchbend is also available as a modulation source.
User’s Manual Pulse • PulsePlus
39
9.4 Aftertouch as a Modulation Source
Aftertouch and the product of Aftertouch and the LFO1 signal are available as modulation
sources in the Pulse. They can used for any application where Control Change messages
are accepted.
9.5 System Exclusive Data Transmission
System exclusive data transmission lets you send and receive the contents of the Pulse's
memory via MIDI (dump).
The following types of dump are supported:
• Program Dump
Transfer of an individual program
• Program Bulk Dump
Transfer of all sound programs for backup
• Global Parameter Dump
Transfer of the global parameters
The appendix contains a table with detailed information on the diverse dump formats.
Sending System Exclusive Data
When you activate the send functions, the Pulse sends the contents of its memory to the
MIDI Out jack. Using a sequencer, you can record and archive these data.
☞
This is how you activate the Dump function:
• Press and hold the Shift key 햺.
• Press the Mode key 햶. This key's alternate function, indicated by the orange
lettering, is Dump.
• Release the Shift key 햺.
• Use the Scroll keys ▲ / ▼ 햻 and 햽 to select the desired Dump function.
Program Dump:
The current program is sent.
Controller Dump:
Transmits all parameters of the current
program as control change messages.
All Dump:
A global parameter dump is sent,
followed by a polyphony parameter
dump, a CV/Gate interface parameter
dump (Pulse Plus only), and a bulk
dump for each program.
�
• Press Dump 햶 again while holding the Shift key 햺 down.
The dump may take a few seconds. The Pulse cannot be played during this time.
Receiving System Exclusive Data
You are not required to activate a special receive mode at the Pulse in order to receive
system exclusive data via MIDI. The transmission is activated via a Dump Request
command originating at the device that is sending the messages.
However, there are a few steps you must execute prior to the transmission.
40
User’s Manual Pulse • PulsePlus
☞
This is how you prepare the Pulse for receiving system exclusive data:
• Check out the parameter Device ID. Data transmission will only be executed
successfully if the receiver and sender setting coincide.
• Make sure none of the Pulse's programs are in Edit mode. All edits that were not
stored prior to the dump will be irretrievably lost!
• Activate the Dump command at the sender device.
• The Pulse will now receive data and store these in its memory.
 Caution:
Data transfer may take up to 20 seconds, depending on the type of
dump. Do not under any circumstances switch the device off, as this
can cause total data loss.
The next step depends on the type of dump you are dealing with:
• If you have executed a program dump, than the incoming program is in Edit mode.
Use the Store command to save the program in the memory location of your
choice.
�
• All data are stored directly in the appropriate memory locations for a bulk dump
and a global parameter dump. You are not required to activate a separate Store
command.
When the Pulse receives a Sysex dump with the Device ID 127, it automatically
loads this data to its memory regardless of the Device ID the Pulse happens to be set
to.
Device ID 127 is a so-called "Broadcast" ID that addresses all connected Pulses.
A checksum of 127 is ignored. In this case, the dump is always accepted as valid.
The Pulse can receive from other devices, but it cannot send a Broadcast ID to other
devices. This function is limited to special computer software.
9.6 Controller Dump
The Pulse features a special dump format that allows you to transmit all parameter values as
Control Change messages. The Controller number and the Controller value of each sound
parameter are sent via the MIDI Out port. This function is designed for pre-initializing
editor software, etc. The dump can be activated in two ways:
• From the front panel. Please refer to paragraph "Sending System Exclusive Data" for
further information.
• Via MIDI Dump Request. See Appendix for details.
9.7 Panic Function
The Panic function sends and executes an "All Notes Off" command. It is used to terminate
stuck notes. To activate this function, simply press the scroll key ▼ 햽 while holding the
Mode key 햶 down.
9.8 Special Features
The Pulse processes incoming Active Sensing messages in accordance with the MIDI
specification. However, Active Sensing messages are not sent.

ARP
An arpeggiator is a device that breaks an incoming MIDI chord down into single notes and
plays them rhythmically. Different sequence modes can be defined for the arpeggiator.
In addition to the synthesis features, the Pulse is equipped with an arpeggiator. It can be
programmed and stored individually for every sound program.
The arpeggiator parameters:
Active

dotted notes are available for every value.
Example: 1/4
Example: 1/8 dotted
Example: 1/16 triplet
Additionally, the Arpeggiator features 16 preset rhythm patterns. These
are entitled r1 through r16.

User’s Manual Pulse • PulsePlus
10.1 Arpeggiator Synchronization via MIDI Clock
The Pulse's Arpeggiator can be used as a master as well as a slave via the MIDI Clock:
• When you use the Arpeggiator as the master, set its speed via the "Tempo"
parameter. The "Global MIDI Channel" parameter must then be set to a value
within the range of A.01...A.16 or A.on. The Pulse will send the Arpeggiator notes
and the MIDI Clock signal via MIDI Out.
• When you use the Arpeggiator as a slave, an external device (e.g. sequencer)
determines the tempo of the Arpeggiator. Set the "Tempo" parameter to "Mid" as
described above. Here too notes and MIDI Clock information can be activated to
control other devices. In this mode, the MIDI Song Position Pointer is also
recognized.
10.2 The Hold Mode
If you set the Active parameter to Hld, the Arpeggiator is in Hold mode. This means that the
incoming MIDI chords generate continuous arpeggios. The Pulse will continue to do so
until you play a new chord or set the parameter back to Off or On. You can also stop the
arpeggiator by performing the panic function or sending an All Notes Off message from
your sequencer.

11. Additional Functions of the Pulse Plus
The Pulse Plus has some additional features for connecting external devices.

 Caution:
Before connecting external components, please make sure that these
units are compatible with the technical specification listed in the
appendix. Waldorf Electronics is not responsible for any kind of
damage on the Pulse or connected devices caused by improper use.
11.2 Audio Input
Via the Audio In jack 쐂 an external audio signal can be fed into the mixing section.
Therefore it’s possible to process the signal by the filter and the VCA. The volume of the fed
in signal is determined by the parameter External of the parameter group MIX .
�
Please keep in mind, that an incoming signal can get to the output section only when
the VCA is triggered. This means that the volume envelope ENV2 has to be started by
an MIDI note. This can be archived by playing on a keyboard or by activating the
built-in arpeggiator.
For this reason, please check the MIDI connections and signal flow first, when you
are not able to hear to external audio source.
Like all other sound parameters, the External value is saved when you store it’s
corresponding program. It’s also possible to use a MIDI Controller to change it.
The sensitivity of the audio input is designed as follows: At a setting of 127 for External, a
signal level of about 250mVeff (about -10dBV, = 0dB semiprofessional level) can be
processed with out any audible distortion. Up to 1Veff signal level can be used in this way
by reducing the External setting. Higher level always cause distortion.
46
User’s Manual Pulse • PulsePlus
11.3 CV/Gate Interface
Via the CV/Gate interface analog synthesizers can be connected to the Pulse Plus. By
offering input and outputs, the Pulse can control a device on one hand, on the other hand,
it can be controlled by a external device. There are also two ways of using the interface: in
combination with the internal sound generation or without.
In detail the following connectors are availiable:
• 1 control voltage input CV In 쐃
• 1 gate input Gate In 쐇
• 2 control voltage outputs CV 1 Out 쐋 and CV 2 Out 쐏
• 1 gate output Gate Out 쐄
Via the inputs CV In 쐃 und Gate In 쐇 the control voltage of an external keyboard or
synthesizer can be transformed into MIDI data. The notes generated on this way can be
used to trigger the sound generation of the Pulse. Also they can be sent out at the MIDI Out
jack for recording and postprocessing.
The output stage of the interface has two seperate connectors, which are designed for
different purposes:
The control voltage at CV 1 Out 쐋 is following the pitch. It can be scaled linear or
logarithmic and is intended to be used for controlling oscillating devices.
CV 2 Out 쐏 is an additional control voltage output for modulation controls. It can be
routed to a choosable modulation source of the Pulse. A possible application for using this
output is controlling the cutoff frequency of a connected synthesizer.
Gate In 쐇 and Gate Out 쐄 have a separately switchable polarity parameter. At the output
the level can be switched between 5V and 12V. This provides the most possible flexibility.
The parameter setting of the CV/Gate interface consists of two main areas:
• Sound parameters for modulation assignment: CV 2 Source and CV 2 Amount.
They are stored in their corresponding program. Please read the chapter
„Modulation“ to get more information.
• Global parameters for configuration and adjustment: CV/Gate Channel, CV In
Adjust, CV In Transpose, Gate In Polarity, Gate Out Polarity, CV Out Curve, CV
Out Adjust, CV Out Offset. They are not depending on the programs.
For troublefree operation of the interface, the proper setting of the discribed global
parameters is required.
�
You can also use a foot switch at Gate In 쐇 to trigger the interface. Use a stereo
phone jack with the following wiring: Tip and Ring connected (Ring is pulled up to
+5V-Level), Switch between Tip/Ring and Ground. In this case the parameter Gate In
Polarity should be set to up.

11.4 Global Parameters
Setting
According to the extended number of global parameters on the Pulse Plus, a different
setting procedure is required.
☞
This is how you make changes to the global parameters:
• Press the Mode key 햶 repeatedly until the LED 햷 next to parameter group GLB
(Line 4) illuminates.
• Turn the rotary 햹 below the parameter Select (knob 5).
The display now shows the code of the
currently chosen parameter.
Example: Mastertune
• To change the chosen parameter, turn the rotary 햹 below Value (knob 6).
The display now shows the value of the
desired parameter.
Example: 440Hz for Mastertune
• If you want to setup more global parameters, just repeat the last two steps.
MIDI-/System Parameters

CV/Gate Parameters
CV/Gate Channel
MIDI send and receive channel for the CV/Gate
interface
Off, 1...16
Off
Example: Channel 3
When this parameter is set to Off, the Pulse sends out the played notes via CV
1 Out 쐋 and Gate Out 쐄. An incoming control voltage at CV In 쐃 and Gate
In 쐇 triggers the sound generation of the Pulse.
When the parameter is set to 1...16, the CV/Gate interface is operating
independently. Received notes on the selected Channel are sent out as control
voltages via CV 1 Out 쐋 and Gate Out 쐄. Incoming control voltages at CV In
쐃 and Gate In 쐇 are transformed into notes and sent on the selected channel.
The internal sound generation will not be affected.
CV In Adjust
Adjust parameter for the CV In input.
-64...+63
To proceed the adjustment, connect the CV output of the keyboard to the CV In
input 쐃 of the Pulse. Connect the Gate jacks in the same way. Now adjust the
parameter to a value, that causes the Pulse to generate a proper tune on the
played notes.
Please note that the CV In input can operate with linear scaled control voltages
of 1V/Octave only.
User’s Manual Pulse • PulsePlus

Please note, that the scaling method is depending on the type of connected
synthesizer. When using the wrong setting, the adjustment described below can
not be proceeded correctly.
CV Out Adjust
Adjust parameter for the CV 1 Out output
(Spread).
-64...+63
CV Out Offset
DC Offset for CV 1 Out and CV 2 Out.
-64...+63
To proceed the adjustment, connect the CV Out 1 output 쐋 of the Pulse to the
CV input of the synthesizer. Connect the Gate jacks in the same way. What to
do next depends on the scaling method of the output signal, which is
controlled by the parameter CV Out Curve:
• On linear scaling, first set both CV Out Adjust and CV Out Offset to
0. Now change the spread via CV Out Offset until the synthesizer
plays a tempered scale. Then tune the absolute pitch via CV Out
Adjust.
�
• On logarithmic scaling, first adjust the spread via CV Out Adjust.
Then use CV Out Offset to fine tune the pitch.
The parameters of the CV/Gate interface can be transmitted as a seperate sysex dump.
By forcing an All Dump manually or via a Dump Request message, the CV/Gate
Interface Parameter Dump will be transmitted. The corresponding data format is
described in the appendix.

12. Stacking two or more Pulses
The Pulse offers a special function that makes it possible to combine two or more Pulses
and play them polyphonically.
The basic steps for achieving this are:
• Make sure all Pulses have a software release 2.00 or higher
• Connect all Pulses’ audio outputs to a mixer or a summing amp
• Chain all Pulses via MIDI thru/in just like normal synthesizers
• Set all Pulses to the same MIDI channel
• Assign each Pulse a unique identification.
Assigning a unique Identification to each Pulse
To ensure proper operation, each Pulse must have a unique indentification number.
☞
This is how you set each Pulse’s identification number:
• Press and hold the Shift key 햺.
• Press the Mode key 햶. This key's alternate function, indicated by the orange
lettering, is Dump.
• Release the Shift key 햺.
• Use the Scroll keys ▲ / ▼ 햻 and 햽 until the display shows alternating:
" 1 of 1 ". This means "I am Pulse #1 of a stack of #1 Pulses". This is the same as
one monophonic Pulse.
• Use the both leftmost rotary pots to alter these values. In case you have three
Pulses, the display must show this:
Pulse #1:
1 oF 3
(Pulse #1 of 3)
Pulse #2:
2 oF 3
(Pulse #2 of 3)
Pulse #3:
3 oF 3
(Pulse #3 of 3)
or in case you have five, they should show this:

• Press Dump 햶 again while holding the Shift key 햺 down in order to synchronize
the voice allocation.
Playing the polyphonic Stack
For the first try, select a sound program that has no arpeggiator active, same for all Pulses
(e.g. factory preset #51). By sending MIDI data, you are now finally ready to play a
polyphonic stack of Pulses. Each Pulse will play one note of an incoming chord.
52
User’s Manual Pulse • PulsePlus
Editing Sound Parameters for the whole Stack
You will notice, that as soon as you edit one of your Pulses, the sound will only change for
that particular voice. There are two ways to get around this:
• If you use a computer, connect the MIDI out from one of your Pulses, but not the
first one marked " 1 oF ...“, to a MIDI input of your computer and merge the
controller data to the MIDI output that goes to the other Pulses. In case of Program
Change, be sure all Pulses contain the same soundset or send the new sound as
SysEx or as Controller dump from this special Pulse.
• If you do not use a computer or you have no more MIDI input, simply connect
MIDI in of the second Pulse to MIDI out of the first one instead of MIDI thru. The
received Notes, Pitch-Bend messages and Controller data are also sent to MIDI out
of the first Pulse. In addition, on each Program Change, the first Pulse sends the
new patch either as controller data or, if it is a factory preset, as a Program Change
message. This way, all editing, Program selecting is done by the first Pulse and all
others are always playing exactly the same sound. Be sure to have Arpeggiator Note
sending disabled, this will destroy the voice allocation. If, for any reasons, some
Notes are playing on two Pulses and others are not playing at all, the voice
allocation is confused. Simply execute the Panic Function on the first Pulse, this
will send some All-Notes-Off messages and all Pulses will reinitialize their voice
allocation.

13. Tips and Tricks
Here are a few tips that will help you make the most of your Pulse.
• The lower the input signal, the greater the effect the filter has on the overall sound.
If you want a heavily filtered sound, set the oscillators' volume parameters to low
values in the mixer. On the other hand, high oscillator levels produce purer sounds.
• If you want a more aggressive sound, simply turn up the oscillator volume levels so
that they are just below the saturation point. The mixer's output signal will crosstalk
with the filter frequency and produce a rougher sound.
• You can achieve typical analog synthesizer distortion by overloading the connected
mixing console's input. You can also experiment by patching effects processors
between the Pulse and your mixer.
• Try using an LFO to modulate the panorama position. This produces interesting
stereo effects, especially at high LFO frequencies.
• The Pulse's output signal is not interrupted when you change programs. Try
exploiting this feature by using MIDI program change messages to line up a series
of different sounds.
• Change the relative pitches of the oscillators at musical intervals. Thirds (mediant),
fifths (dominant) and sevenths (subtonic) are suitable for this application.
• Self-oscillation of the filter at high resonance values produces sounds that are great
for soloing.
• Modulate the oscillator's pitch drastically so that the upper frequency threshold is
exceeded. This will produce interesting results.
• Program a pitch modulation in musical intervals. The section entitled "Modulations"
contains an assignment table listing the Mod Amount parameters and the
corresponding semitone intervals. For example, you can modulate from a major
chord to a minor chord via the mod wheel.
• Assign a Keytrack modulation to the LFO speed. It should modulate the LFO in
proportion to the incoming note. You can thus achieve even frequency fluctuations
over a wide range of your keyboard.
• Modulate the pitch of an oscillator via Keytrack. Set the modulation "Amount" so
that this value is numerically equal to the "Tune" value of the oscillator, but make
one value positive and the other negative. This generates frequency fluctuations that
oscillate at the same speed throughout the range of the keyboard. Experiment with
different Amount values by alternating low and high notes.

User’s Manual Pulse • PulsePlus
14. Trouble-Shooting
If you run into any problems with your Pulse, please consult the checklist below. Many
perceived errors are just minor oversights that can be corrected quickly. If you still can't
solve the problem, please contact a qualified repair center or Waldorf Product Support. The
address and telephone number are printed on the warranty card.
Error
Corrective Action
The device does not respond to MIDI
data.
Check the MIDI channel setting in the
MIDI Channel parameter. Note that
this parameter is a global parameter
and consequently pertains to all
programs
The device does not respond properly
to the parameter values you have
entered, e.g. the filter significantly
dampens the signal even at maximum
cutoff setting.
Make sure a modulation is not
influencing a parameter. In this
example, an envelope with a negative
modulation value could be lowering
the filter cutoff frequency.
The filter is not tuned properly.
Ensure the parameter values for the
filter's Cutoff and Keytrack are correct.
If you cannot correct the error, call up
the Filter Tune function.
Pulse Plus only:
The Pulse is playing after powering up
or notes are hanging.
Change the setting of the Gate In
Polarity parameter.

14.1 Tuning the Filter
The filter is tuned at the factory prior to shipping and, as a rule, is very stable. However, the
Pulse is an actual analog synthesizer, so diverse factors may cause slight tuning problems.
Therefore we recommend that you re-calibrate it from time to time. On demand, the Pulse
executes this function automatically.
☞
This is how you activate the Filter Tune function:
• Press the Shift key 햺 and hold it down.
• Briefly press the Mode key 햶. You are now at level at which Sysex data transfer is
executed. The Filter Tune function is also located here.
• Release the Shift key 햺.
• Use the scroll key ▲ 햻 to call up the Filter Tune function. It is located right after
the All Dump function.
Filter Tune:
• Press Dump 햶 again while holding the Shift key 햺 down.
The filter is tuned automatically.
This process can take up to 30 seconds. The following functions are executed:
• First, the filter is tuned to its fundamental frequency. This means the filter is
adjusted to 440Hz at maximum oscillation of the resonance frequency. The display
indicates the current value for the filter cutoff frequency.
�
56
• Then the filter is tuned an octave above the fundamental frequency, i.e. to 880Hz.
The Pulse's audio output is switched off during the filter tuning process. Once the
filter has been tuned properly, the Pulse is ready to be played.
The Filter Tune function can also be activated via a MIDI Tune Request command.
Conversely, the Pulse sends a MIDI Tune Request when the "Tune" function is
activated.

Glossary
Aftertouch
The majority of contemporary keyboards are capable of generating aftertouch messages. On
this type of keyboard, when you press harder on a key you are already holding down, a
MIDI Aftertouch message is generated. This feature makes sounds even more expressive
(e.g. through vibrato).
Amount
Describes to which extent a modulation influences a given parameter.
Attack
An envelope parameter. "Attack" is a term that describes the ascent rate of an envelope
from its starting point to the point where it reaches its highest value. The Attack phase is
initiated immediately after a trigger signal is received, i.e. after you play a note on the
keyboard.
Control Change (Controllers)
MIDI messages enable you to manipulate the response of a sound generator to a significant
degree.
This message essentially consists of two components:
• The Controller number, which defines the element to be influenced. It can be
between 0 and 127.
• The Controller value, which determines the extent of the modification.
Controllers can be used for effects such as slowly swelling vibrato, changing the stereo
panorama position and influencing filter frequency.
CV
CV is the abbreviation for control voltage. In analog synthesizers, control voltages are used
to control sound parameters like pitch, cutoff frequency etc. E.g. to get a tremolo effect, the
output signal of a LFO must be routed to the CV input of an (or several) oscillator(s).
Decay
"Decay" describes the descent rate of an envelope once the Attack phase has reached its
zenith and the envelope drops to the level defined for the Sustain value.
Filter
A filter is a component that allows some of a signal's frequencies to pass through it and
stops other frequencies. The most important aspect of a filter is the filter cutoff frequency.
Filters generally come in four categories: low-pass, high-pass, band-pass, and band-stop. A
low-pass filter dampens all frequencies above the cutoff frequency. A high-pass filter in turn
dampens the frequencies below the cutoff. The band-pass filter allows only those
frequencies around the cutoff frequency to pass, all others are dampened. A band-stop filter
does just the opposite, i.e. it dampens only the frequencies around the cutoff frequency.
The most common type is the low-pass filter.
Filter Cutoff Frequency
The filter cutoff frequency is a significant factor for filters. A low-pass filter dampens the
portion of the signal that lies above this frequency. Frequencies below this value are
allowed to pass through without being processed.
70
User’s Manual Pulse • PulsePlus
Envelope
An envelope is used to modulate a sound-shaping component within a given time frame so
that the sound is changed in some manner. For instance, an envelope that modulates the
cutoff frequency of a low-pass filter opens and closes this filter so that some of the signal's
frequencies are filtered out. An envelope is started via a trigger, usually a fixed trigger.
Normally, the trigger is a MIDI Note. The classic envelope consists of four individually
variable phases: Attack, Decay, Sustain and Release. This sequence is called an ADSR
envelope. Attack, Decay and Release are time or slope values, and Sustain is a variable
volume level. Once an incoming trigger is received, the envelope runs through the Attack
and Decay phases until it reaches the programed Sustain level. This level remains constant
until the trigger is terminated. The envelope then initiates the Release phase until it reaches
the minimum value.
Gate
The term „Gate“ has different meanings in a technical context. Like a real gate, it describes
something, that can be open or closed, or - to use a technical term - active or inactive. A
gate in sense of a device is a unit, that damps a throughpassing signal corressponding to
some specific conditions. E.g. in a noise gate a signal is cut off, when its level falls above a
predetermined threshold.
Gate stands also for a control signal of analog synthesizer systems. A keyboard generates an
active gate signal as long as a key is held down. When the key is released, the gate signal
becomes inactive again. An envelope generator can use this signal for its trigger purposes,
and as a result a VCA unit can be controlled.
LFO
LFO is an acronym for low-frequency generator. The LFO generates a periodic oscillation at
a low frequency and features variable waveshapes. Similar to an envelope, an LFO can be
used to modulate a sound-shaping component.
Low-pass Filter
Synthesizers are often equipped with a low-pass filter. A low-pass filter dampens all
frequencies above its cutoff frequency. Frequencies below the cutoff are not affected.
MIDI
The acronym MIDI stands for "musical instrument digital interface." It was developed in the
early '80s so that diverse types of electronic musical instruments by different manufacturers
could interact. At the time a communications standard for heterogeneous devices did not
exist, so MIDI was a significant advance. It made it possible to link all devices with one
another through simple, uniform connections.
Essentially, this is how MIDI works: One sender is connected to one or several receivers.
For instance, if you want to use a computer to play the Pulse, then the computer is the
sender and the Pulse acts as the receiver. With a few exceptions, the majority of MIDI
devices are equipped with two or three ports for this purpose: MIDI In, MIDI Out and in
some cases MIDI Thru. The sender transfers data to the receiver via the MIDI Out jack. Data
are sent via a cable to the receiver's MIDI In jack.
MIDI Thru has a special function. It allows the sender to transmit to several receivers. It
routes the incoming signal to the next device without modifying it. Another device is
simply connected to this jack, thus creating a chain through which the sender can address
a number of receivers. Of course it is desirable for the sender to be able to address each
device individually. Consequently, there is a rule which is applied to ensure each device
responds accordingly.
User’s Manual Pulse • PulsePlus
71
MIDI Channel
This is a very important element of most messages. A receiver can only respond to
incoming messages if its receive channel is set to the same channel as the one the sender is
using to transmit data. Subsequently, the sender can address specific receivers individually.
MIDI Channels 1 through 16 are available for this purpose.
MIDI Clock
The MIDI Clock message determines the tempo of a piece of music. It serves to
synchronize processes based on time.
Modulation
A modulation influences or changes a sound-shaping component via a modulation source.
Modulation sources include envelopes, LFOs or MIDI messages. The modulation
destination is sound-shaping component such as a filter or a VCA.
Note on / Note off
This is the most important MIDI message. It determines the pitch and velocity of every
generated note. The time of arrival is simultaneously the start time of the note. Its pitch is
derived from the note number, which lies between 0 and 127. The velocity lies between 1
and 127. A value of 0 for velocity is similar to „Note Off“.
Panning
The process of changing the signal's position within the stereo panorama.
Pitchbend
Pitchbend is a MIDI message. Although pitchbend messages are similar in function to
control change messages, they are a distinct type of message. The reason for this distinction
is that the resolution of a pitchbend message is substantially higher than that of a
conventional Controller message. The human ear is exceptionally sensitive to deviations in
pitch, so the higher resolution is used because it relays pitchbend information more
accurately.
Program Change
These are MIDI messages that switch sound programs. Program numbers 1 through 128 can
be changed via program change messages.
Release
An envelope parameter. The term "Release" describes the descent rate of an envelope to its
minimum value after a trigger is terminated. The Release phase begins immediately after the
trigger is terminated, regardless of the envelope's current status. For instance, the Release
phase may be initiated during the Attack phase.
Resonance
Resonance is an important filter parameter. It emphasizes a narrow bandwidth around the
filter cutoff frequency by amplifing these frequencies. This is one of the most popular
methods of manipulating sounds. If you substantially increase the resonance, i.e to a level
where the filter begins self-oscillation, then it will generate a relatively clean sine
oscillation.
Sustain
An envelope parameter. The term "Sustain" describes the level of an envelope that remains
constant after it has run through the Attack and Decay phases. Sustain lasts until the trigger
is terminated.
72
User’s Manual Pulse • PulsePlus
System Exclusive Data
System exclusive data allow access to the heart of a MIDI device. They enable access to
data and functions that no other MIDI messages are able to address. "Exclusive" in this
context means that these data pertain only to one device type or model. Every device has
unique system exclusive data. The most common applications for SysEx data include
transfer of entire memories and complete control of a device via a computer.
Trigger
A trigger is a signal that activates events. Trigger signals are very diverse. For instance, a
MIDI note or an audio signal can be used as triggers. The events a trigger can initiate are
also very diverse. A common application for a trigger is when it is used to start an
envelope.
VCA
VCA is the acronym for voltage-controlled amplifier. A VCA is a component that influences
the volume level of a sound via a control signal. This control voltage is often generated by
an envelope or an LFO.
VCF
VCF is the acronym for voltage-controlled filter. It is a filter component that allows you to
manipulate the filter parameters via control voltages.
Volume
The term describes a sound's output level.
