Tempest Manual Addendum
OS Version 1.2
Tempest was originally released with the version 1.0 operating system. Since that
time, we have released new version 1.1 and 1.2 operating system updates. This
document describes the new features that have been added in these two updates.
Here is a summary of those additions:
OS 1.2
• Polyphonic MIDI keyboard play
• Undo Record
• Sound Bank B
• Odd time signatures
• Export multiple files for data backup
• Beat-wide effects during 16 Mutes mode
• Improved sequencer timing
OS 1.1
• Reverse playback
• Change sounds quickly from Pads screen
• Load Drum Kits
• Erase all notes from a beat
• Time shift of individual notes
• Sync to other devices by MIDI Clock
• Playing sounds from MIDI; sending MIDI from pads
• Turn off stuck notes
• Master Transpose and Fine Tune
• Adjustable pad touch response
• MIDI local control
• Various new system settings
Each of these new features is described in the following pages, in the order
shown above.
Polyphonic MIDI Keyboard Play
Tempest now doubles as a 6-voice polyphonic analog keyboard synthesizer, playing the selected sound polyphonically and responding to your MIDI keyboard’s
sustain pedal and pitch bend wheel. This feature was first implemented in OS
version 1.1 but was substantially improved in version 1.2. To use this feature,
there are three new settings in the System menu, accessed by pressing System.
MIDI: Synth IN Channel: Off, 1…16—Sets the channel on which one of
Tempest’s Sounds can be played from an external MIDI keyboard or other MIDI
controller, or a MIDI sequencer. Used strictly as a MIDI sound module, Tempest
behaves as a six-voice analog poly synth. It responds to note messages and the
“standard” controllers (pitch bend, mod wheel, aftertouch, channel pressure, etc.),
provided that the Sound has those modulation sources routed to some destination.
When used to record notes to Tempest’s sequencer, the external keyboard or
controller controls the note’s pitch, but otherwise acts much the same as recording from a pad: only one note can be recorded at a time. Velocity and duration
are also recorded. Timing is subject to the current Quantize setting. Because the
sequencer is event-based, continuous controllers such as pitch bend, mod wheel,
and aftertouch are ignored.
MIDI: Synth IN Channel must be set to a different channel than MIDI: IN
Channel in order to function properly. If they are set the same, the note-to-pad
mapping detailed under “Playing Sounds From MIDI; Sending MIDI From Pads”
on page 10 overrides the MIDI: Synth functionality.
Note: Notes played via MIDI are prioritized higher than notes played by
Tempest’s sequencer, so the sequencer should not steal voices while notes
are playing via MIDI. Notes played by the pads have the same priority as
MIDI notes, so they can steal voices from MIDI notes and vice versa.
MIDI: Synth Sound: A1…A16—Used to choose the pad—and its assigned
Sound—that plays on the MIDI: Synth IN Channel. Because this is currently
a system-level setting, MIDI data will be routed to the chosen pad, regardless of
the loaded Beat or Project.
MIDI: Synth Root Note: C0…C10—Sets the note at which the external MIDI
controller plays the Sound at the same pitch as playing it from the pad in 16
Sounds mode. For example, let’s say the pad plays the sound as an A. In order to
play the Sound from a MIDI keyboard without transposing, MIDI: Synth Root
Note should also be set to an A, perhaps A4 or A5 to play in close proximity to
middle C on the keyboard.
Pitch Bend Amount
There is a new setting in the Sounds screens to set to the pitch range over which
Tempest will respond to MIDI pitch bend messages. The bend range is set
individually for each sound. To adjust it, select 16 Sounds (in the Pad Function section) and select Sounds (in the Screens section). Then press Page Down
repeatedly until the last screen appears, entitled “Misc.” The rightmost setting is
Pitch Bend Amount, with a range of 0 to 12 semitones (one octave). The default
setting is 2 semitones.
Undo Record
If the Undo Rec light is on, this means there is something to undo. Pressing Undo
Rec will undo all recording changes made during the last recording pass (since
you last turned the Rec key on) and will turn off the light.
Pressing Undo Rec a second time before starting to record again will redo back to
the state before you pressed the key. This is a single-level undo/redo.
Note: The Undo Sound function (the Shift function of the same key) is not
yet implemented.
Sound Bank B
Sixteen additional Sounds can now be stored and accessed per Beat for a total
of 32. Sounds in bank B are designated B1 through B16. Press Sound Bank B to
toggle between banks A and B.
1. While holding Copy to copy a sound, use Sound Bank B to switch between
2. To erase a Sound in Sound Bank B from a Beat, select Sound Bank B
before or after holding Erase, and then hit a pad to erase that sound.
Odd Time Signatures
Tempest’s beats are no longer limited to 4/4 time signature. Now you can have
any time signature with a lower value of 4, 8 or 16, and an upper value of
between 2 and 64. However, a beat’s total length can be no greater than 64 16th
notes (for example, 4 bars of 4/4 or 1 bar of 64/16) and all measures within a beat
must have the same time signature. Odd time signatures are implemented in two
features: Initialize Beat and the new Change Time Signature of Beat function.
Initialize Beat
This initializes any Beat to default settings at the specified time signature and
number of bars, erasing any previous contents.
To initialize a beat, press Erase and Copy together to view the Edit menu,
then select Initialize Beat. Enter the Beat to initialize, the Time Signature and
Number of Bars, then press the Init Now soft key.
Change Time Signature of Beat
This function allows you to change the time signature of all measures within a
beat. If the new time signature is shorter, the notes at the end of each bar will be
truncated. Or if the new time signature is longer, the notes at the beginning of
each bar will be copied to the end of the bar to fill the new space. You can also
change the number of bars in the beat. If the new number of bars is greater, the
notes in the earlier bars are copied to the new bar(s) at the end. Or if the new
number of bars is lesser, the ending bars are deleted entirely.
To change time signature, press Erase and Copy together to view the Edit menu,
then select Change Time Signature of Beat. Enter the beat, new time signature
and number of bars, then press the Set Sig Now soft key.
This function works in conjunction with the Undo Rec function so that your time
signature change can be undone. Note that the Undo Rec function is single-level,
holding only your last change, so if you change the time signature then record
new notes into the beat, you will lose the ability to undo your time signature
The USB port on the rear of Tempest can now be used to send or receive any of
the MIDI data that the MIDI ports can. In the System menu, there are three new
settings that permit you to select the MIDI or USB port for your MIDI data:
• MIDI: Clock In Cable
• MIDI: Clock Out Cable
• MIDI: Sysex IN+OUT Cable
Also, in the Save/Load menu, the four Export functions (Export Sound, Beat,
Project or File) now permit you to select either the MIDI or USB port in order
to send the MIDI system exclusive data. And if the Sysex IN+OUT Cable
setting (in the System menu) is set to USB, then MIDI system exclusive transfers
received over USB will automatically be loaded, just as with the MIDI port.
Note: USB Sysex transfers are only supported in Mac OSX and Windows 7.
Export Multiple Files for Data Backup
The Export File Over MIDI function (in the Save/Load menu) now has the
ability to export multiple files over MIDI or USB in a single action. This can be
handy for backing up many or all of your Tempest files to a system exclusive
librarian application on your computer. Note that Tempest sends the multiple files
sequentially, one after another, and that system exclusive librarian applications
will capture all the files as one large system exclusive dump.
When Tempest exports a file, its location in Tempest’s flash memory is remembered within the file. When you later reload the file, it will be loaded into its
original location, overwriting any file in the same folder having the same name. The new Soft Knob 4 has 4 options:
File (default)—Select a single file.
Folder—Select all files in the selected folder for export.
Type—Select all folders in the selected Type (Sound, Beat, or Project) and all
files within those folders for export.
All—Select all files and folders for export.
For example, if you select All, all files of all types in all folders will be exported
in one step. A system exclusive librarian application on your computer should be
used to capture the entire dump as one large system exclusive file. In the unlikely
event of a Tempest failure that causes all data to be lost (or to load the same
data into another Tempest), you can send the same file to the Tempest from your
system exclusive librarian application.
Note: When sending a large, multi-file system exclusive dump to Tempest
from your system exclusive librarian, you should set your the librarian’s
settings to include a one-second pause between individual system exclusive
messages (the Sound, Beat, or Project files). This will insure that Tempest
has enough time to respond to each new file in the received system exclusive
data stream.
Beat-wide effects during 16 Mutes mode
Before version 1.2, when 16 Mutes was selected, the Real-Time FX sliders and
sound controls would affect only the selected sound. This is now changed so that
when 16 Mutes is selected, the Real Time FX sliders and sound controls affect
beat-wide effects, just as they do when 16 Beats is selected. This is more useful
during performance.
Improved Sequencer Timing
The timing accuracy of the Tempest sequencer has been improved. When syncing
to received MIDI Clock, the timing jitter (timing deviation from source clock)
has been reduced from about 5 ms to about .5 ms, a tenfold improvement. The
timing jitter in sent MIDI Clock is reduced from about 1 ms to about .3 ms.
The following features were added in OS version 1.1.
Reverse Playback
Reverse causes Sounds—even completely analog, non-sample-based Sounds—to
play in reverse by reversing the envelopes. (Sample-based Sounds also play the
sample in reverse.) Reverse is a real-time, performance control in 16 Sounds and
16 Beats modes and it can also be recorded into a Beat on a per note basis.
While playing a Beat in 16 Sounds mode, turning Reverse on and playing a pad
will cause the Sound to play in reverse. While recording a Beat in 16 Sounds
mode, notes recorded with Reverse on will record and play in reverse.
Note: Reverse has also been added to the parameter list in the Beat Events
screen and can be turned on or off for individual notes. For details about the
Beat Events screen, see “Events key: the Beat Events screen” on page 12 of
the Tempest Operation Manual.
While playing a Beat in 16 Beats mode, Reverse causes all of the Sounds in a
Beat—but not the Beat itself—to play in reverse.
Change Sounds Quickly from “Pads” Screen
A new parameter, Load Sound, has been added to the Pads screen in 16 Sounds
mode, enabling Sounds for the selected pad to be auditioned and changed.
In Pads view, strike a pad to select a Sound and then turn the Load Sound soft
knob clockwise to load the first available Sound of the current Sound directory.
Continue scrolling through the list to audition different Sounds or use the Sound
Directory soft knob to change to a different directory of Sounds. Press the
Revert soft key to revert to the saved Sound.
Note: Revert is available until another pad is struck in 16 Sounds mode.
Pads can be struck in any other Pad Function mode, but once another Sound
pad is struck, Revert is unavailable. To return to the saved settings, reload
the file.
Load Drum Kits
Tempest is now able to load only the sounds from a Beat file, overwriting only
the sounds in the destination file. This provides the equivalent of loading drum
kits, but with the added flexibility that any Beat file can be used as the equivalent
of a “drum kit” file. This is accomplished by an enhancement to the Load Beat
function: the ability to load only the sounds or other selective parts of the file.
Press Save/Load, then select the Load File option from the menu. In the Load
File screen, select a Beat file to load then press the Next soft key. The Load Beat
screen will appear, but with a new Soft Knob 1 called Load Options containing
five options:
Load Options
Dest Beat
Load Beat “A Bouncy C”:
Load Now
14/Fast beat #2
Free 2.5MB
Normal—All Beat data will be loaded into the destination Beat.
Sounds + Mixer—Only the Sounds and mixer settings will be loaded.
Sounds Only—Only the Sounds will be loaded. Use this option to load only
the sounds (the drum kit) from the Beat.
Sequencer + Note FX—Only the sequence and Note FX settings will be
Beat FX—Only the Beat FX settings will be loaded.
For more information, see “Loading Sounds, Beats, and Projects” in the Tempest
Operation Manual.
Erase All Notes from a Beat
All notes in a Beat can now be erased in one step, in either 16 Sounds or 16
Beats mode.
In either 16 Sounds or 16 Beats, press and hold Erase, and then press the Erase
All Notes soft key. All notes in the current Beat are erased.
Time Shift of Individual Notes
Time Shift has been added to the list of parameters in the Beat Events screen.
Tempest’s sequencer resolution is 96 PPQN (parts per quarter note). Time Shift
allows a note to be shifted +/- 3 parts. At 120 BPM, 1 part equals about 5.2 milliseconds.
For details about the Beat Events screen, see “Events key: the Beat Events
screen” in the Tempest Operation Manual.
Sync to Other Devices Using MIDI Clock
Tempest can now be synchronized with other devices by using standard MIDI
Clock. A new setting, MIDI: Clock Mode has been added to the System menu:
MIDI: Clock Mode: Off, Master, Slave, Slave Thru—In Master mode,
Tempest transmits MIDI clock and start, stop, and continue messages.
In Slave mode, Tempest syncs to incoming MIDI clock and responds to start,
stop, and continue messages. When slaved to an external MIDI clock, Tempest’s
Tempo display is preceded by “EXT.” The master BPM (beats per minute) is not
transmitted via MIDI as a numerical value, so Tempest must calculate the BPM
from the incoming clock, and the value displayed by Tempest is subject to rounding and the accuracy of the master clock. In other words, Tempest’s displayed
BPM value may be slightly different from the master’s, even though they’re
perfectly synced.
In Slave Thru mode, Tempest syncs to MIDI clock and forwards incoming
MMC and clock messages to the MIDI Out port.
Note: In Slave and Slave Thru modes, if no MIDI clock is present at the
selected input, Tempest will not play.
When clock mode is set to Off, MIDI clock is neither transmitted nor received.
Playing Sounds From MIDI; Sending MIDI From Pads
Tempest now has the ability to remotely trigger its sounds from received MIDI
Note On messages, as well as the ability to send MIDI Note On messages in
response to playing the drum pads. This is provided by two new settings in the
System menu:
MIDI: IN Channel: All, 1…16—Sets the incoming MIDI channel for MIDI
note-to-pad playback and recording. The note-to-pad mapping is derived from
the General MIDI standard drum mapping.

Note: Notes played via MIDI take priority over notes played by Tempest’s
sequencer, just as notes played from the pads do.
MIDI: OUT Channel: Off, 1…16—Sets the channel on which Tempest’s pads
transmit MIDI note and velocity data. The pads transmit MIDI data in 16 Sounds,
16 Tunings, and 16 Levels modes. The note-to-pad mapping is the same as what
is described in “MIDI: IN Channel,” regardless of the Pad Functions mode. In 16
Levels mode, played velocity is ignored and the pad’s assigned velocity level is
When set to Off, note and velocity messages are not transmitted (but clock and
start/stop/continue messages are).
Note: The current version of the OS uses Tempest’s default note-to-pad
mapping even in 16 Tunings mode, so the transmitted MIDI notes don’t
correspond to the notes in the 16 Tunings screen.
Turn Off Stuck Notes
Tempest is capable of being played from the internal sequencer, the pads, and the
MIDI input simultaneously. If a stuck note should occur, simply press Left Shift
+ Right Shift + Stop to force all the voices off.
Master Transpose and Fine Tune
The pitch of all sounds can now be adjusted, both coarsely and finely, by two
new settings in the System menu:
Master Transpose: -12…+12—Transposes the pitch of all voices in half-step
increments, as much as one octave up (+12) or down (-12).
Fine Tune: -50…+50—Transposes the pitch of all voices in one cent incre-
ments, as much as a quarter-tone up (+50) or down (-50).
Pad Velocity Curve
A new setting in the System menu, Pad Velocity Curve, permits the velocity
response curve for Tempest’s pads to be selected from four different sensitivity
levels from 1 to 4. The default value is 2.
MIDI Local Control
This new addition to the System menu performs a similar function to MIDI Local
Mode on keyboard synthesizers-- it internally disconnects the drum pads from
the sound generator. This is useful, for example, if you are using Tempest with
an external MIDI sequencer and wish to avoid sounds playing twice for each pad
hit, due to notes being sent and rerouted back over MIDI to Tempest. When Off,
the pads transmit note and velocity messages via MIDI as normal, but will not
cause Tempest’s internal sounds to play. By default, this is set to On.
Various Panel Behavior Settings
These five new settings in the System menu permit you to customize the behavior
of certain panel controls.
Touch Slider Latch Mode: Active Only, All—When set to Active Only (the
default) and Latch On is active, the latched slider value is reset to 0 when switching between FX1 and FX3, playing another pad, or switching between 16 Sounds
and 16 Beats modes. FX2 and FX4 behave similarly.
When set to All and Latch On is active, the slider values stay latched for a given
Sound, even when switching among FX1, FX2, FX3, and FX4, playing other
pads/Sounds, or switching between 16 Sounds and 16 Beats. Turning latch off
resets all latched values to 0.
For details about the touch sliders, see “Real Time FX” on page 35 of the
Tempest Operation Manual.
Latch Button behavior: Normal, Shift Switched, Disabled—In Normal
mode, the touch slider remains at the last value when Latch On is active.
In Shift Switched mode, the un-shifted and shifted behaviors are swapped. That
is, the Latch On buttons now switch between FX1 and FX3 or FX2 and FX4.
Shift + Latch On turns latch on and off.
When set to Disabled, the Latch On buttons simply switch between FX1 and
FX3 or FX2 and FX4 and the latch function is disabled.
For more details about Latch On, see “Real Time FX” on page 35 of the Tempest
Operation Manual.
Envelope Amount Encoder behavior: Normal, Shift Switched—In
Shift Switched mode, the un-shifted (Amount) and shifted (Velocity Amount)
behaviors are swapped. That is, when Shift is off, the encoder controls Velocity
Amount and when on, Amount.
Select Sound behavior: Shift On + Pad, Shift Held + Pad—The default
behavior (Shift Held + Pad) is slightly different from what is described on
page 5 of the Tempest Operation Manual. To select a Sound for editing without
playing the Sound, hold Shift down and press the desired pad. When set to Shift
Held + Pad, the pads can still be played when Shift is on.
When set to Shift On + Pad, Shift must either be on or held down to select the
Tap Tempo behavior: Shift On + Play, Shift Held + Play—With Tempest’s
default behavior (Shift Held + Play), Shift must be held to tap the tempo. Otherwise, Play starts/restarts the Beat, whether Shift is on or not. When set to Shift
On + Play, Play is used to tap the tempo when Shift is either on or held down.
Manual 1.0 Errata
Assignment of an expression pedal to Note FX 1 through 4 in the System menu
is not yet implemented.
