Introduction
Thanks for purchasing Bachmann’s GRPT140, the latest creation in Digital
Pianos; a mechanical/digital hybrid which unites the best of advanced
electronic technology with traditional high quality craftsmanship for the
instrument’s mechanical parts.
Mechanics
The instrument features a traditional high quality mechanism with a standard
keyboard and mechanical assembly commonly used in acoustic vertical
pianos. A contact system based on optical sensors permits communication
between the instrument’s mechanical parts and the innovative system of
digital sound generation. This system guarantees the perfect reproduction of
all the key parameters interpreted by the digital sound engine without
interfering with the natural “feel” and response of the instrument.
Electronics
The GRPT140 Sound generator consists of a small module located under the
extreme left of the keyboard. The module’s user interface consists of a set of
indispensable controls to place this instrument high among the most easiest to
use electronic digital pianos.
The GRPT140 Module provides a data base consisting of 64 Sounds and
combinations, not to mention the 2 Digital Signal Processors for a selection
of Reverb and Delay/Modulation effects which can be freely assigned to any
sound.
With its 64 note polyphony and 88 note weighted, Hammer Action keyboard,
full MIDI implementation and marvelous piano sound, GRPT140 is the
modern, economical answer to all home piano playing.
The GRPT140 is very easy to use, but to make the most of the instrument’s
features, you are recommended to consult this manual whenever you are not
sure what to do.

2.
Press the POWER switch located on the front panel
of the module to turn on the instrument.
After a few seconds, the instrument is ready to play.
Selecting the sounds
3.
Select and play the GRPT140 Sounds
Whenever you turn on your instrument, the module sets to the sound
according to the position of the Sounds knob. The GRPT140 sound
engine contains a vast high quality sound data base with a polyphony
of 64 voices, with 5 sounds recalled directly from the panel:
GrandPiano1, GrandPiano2, El.Piano 1, El.Piano 2, Harpsichord
In addition, the instrument features a User location, which allows you
to set and recall an additional 59 Sounds automatically, for a total of 64
Sounds.
Selecting the various sounds available is via the Sounds knob. This
control is graduated with several snapping positions, each one corresponding to a different Sound.
To pass from the default GrandPiano1 sound to the next, GrandPiano2,
simply rotate the knob through one snap. To select the next sound,
El.Piano1, rotate the knob once again and so on.....
4.
Play on the keyboard and regulate the Volume.
Use the VOLUME control knob to adjust the overall volume level.
This control snaps to the central position which corresponds to an
optimized setting equivalent to the dynamic response of an acoustic
piano.
• Note: When the VOLUME control knob is
set to its lowest position (rotated all to the
left), no sound will be heard.
Selecting the USER sounds
5.
Listen to all the GRPT140 sounds.
The last snap of the Sounds selection knob corresponds to the User
position which allows the selection of the additional 59 Sounds or
sound combinations (refer to the list in the Appendix). Selecting the
User location sets the instrument to play the first sound on the list. By
pressing the DATA + button repeatedly, you can scroll through the
available sounds one by one. The DATA – button selects the sounds
in reverse order. The selections are shown in the display as a number
and once a sound has been selected, it remains automatically memorized at the User location, meaning that every time you select the User
snap, you will recall the memorized sound.
3
Example
a. Select the User position by turning to Sounds
knob.
The instrument sets by default to the sound U01, Wurlie, as shown in
the display.
b.
Now press DATA+.
Using this procedure, select the next sound on the list, U02, FMPiano1,
c. If you now press the DATA– button, you will
return one step backwards to U01.
d. Press DATA+ three times to select U03
Clavinet.
This sound is automatically memorized to the User location. This
means that if you now change sound by rotating the knob, every time
you return to the User position, you will find the sound Clavinet.
6.
Play using the pedals
The GRPT140 is fitted with three pedals: Soft, Sostenuto and Damper
SOFT: The Soft pedal (left) affects the timbre of the sound such that it
plays softer, allowing you to continue using the same playing style at
a lower volume.
Sostenuto The Sostenuto pedal sustains all the notes of the keys
currently pressed. All new notes played after having pressed the pedal
will not be affected.
DAMPER: The Damper pedal applies the Sustain effect to all notes
played. If you release a note after depressing the Damper, the note will
proceed towards its natural decay according to the type of sound played.
The Damper is particularly effective with Piano type sounds. In the
case of Organ and Strings sounds, the notes will be held for as long as
the Damper is depressed.
Note: for all piano type sounds, the notes of the uppermost keys (from E6
to C8) are automatically sustained, such as in an acoustic piano.

The parameters of the selected function are changed with the DATA +/–
buttons. The status of the function appears in the Value display.
The pages which follow describe each function in detail.
7
Rev(erb) Type
A total of 3 different Reverb effects are available, freely selected for each
sound
Off (bypass, no effect); Room; Stage ; Hall
Each reverb effect accurately reproduces the natural reverberation characteristics of typical surroundings, such as a medium sized room (Room), a theatre
(Stage) and a large concert hall (Hall).
To change the reverb
Each GRPT140 sound recalls a factory set reverb setting, which can be
changed at any time.
Example:
1.
Rotate the Sounds knob and select the sound
El.Piano1
2.
Now rotate the Edit knob until you reach the position Rev.Type.
The display will show an abbreviation for the current reverb effect
assigned to the sound (“H a l” Hall).

type
4.
Press the DATA– button and the display shows “S
t g”, to indicate that the reverb type has changed to
Stage. Press the same button again to pass to
Room (r o m), then to Off (Bypass, no effect).
Once you reach the Off setting, it is possible to continue changing the
reverb type. Every time you press the DATA+ button, you will select
in the order: Off, Room, Stage, Hall.
Whatever reverb type is selected (including the Off setting) is automatically memorized, in order that every time you change sound, you
also recall the reverb type assigned to the sound.
These settings remain in memory even after turning the instrument off,
or until changed again (except for the GrandPiano1 sound which recalls
the factory set effect at power up).
8
Efx. Type
A total of 3 different modulation effects are available, freely selected for each
sound.
Off (bypass, no effect); Chorus; Tremolo; Phaser
Each effect has particular modulation characteristics, suitable for most types
of music. These effects add “depth” to the sounds and render them more
interesting.
To change the effect
Each GRPT140 sound recalls a factory set modulation effect setting, which
can be changed at any time by the user.
1.
Rotate the Sounds knob and select the sound
El.Piano1
2.
Now rotate the Edit knob until you reach the position Efx.Type.
The display will show an abbreviation for the current modulation effect
assigned to the sound (“T r e”- Tremolo).
3.
Press the DATA +/– buttons to modify the effect
type
4.
Press the DATA– button and the display shows “C
h o”, to indicate that the effect type has changed to

Once you reach the Off setting, it is possible to continue changing the
effect type. Every time you press the DATA+ button, you will select
in the order: Off, Chorus, Tremolo, Phaser (PHA).
Whatever effect type is selected (including the Off setting) is automatically memorized, in order that every time you change sound, you also
recall the effect type assigned to the sound.
These settings remain in memory even after turning the instrument off,
or until changed again (except for the GrandPiano1 sound which recalls
the factory set effect at power up).
9
Touch
If the keyboard of your GRPT140 is too “hard” or “soft”, you may want to
modify the touch sensitivity. The Touch function allows you to regulate the
velocity response of the sound generator, in relation to the keystrike velocity.
This allows a ‘virtual’ regulation of the keyboard’s touch sensitivity, through
three different response curves:
1 Soft , 2 Normal, 3 Hard.
The default status of the Touch setting is set to Normal (2).
Modifying the response curve
The response curve is a global parameter, meaning that the setting the
instrument as a whole (all the instrument’s sounds).
1.
Select the Touch menu with the Edit knob
Selecting the Touch menu displays the current response curve setting
(default: 2 Normal).
2.
Press the DATA + button and the value will increase
by one unit, therefore, if you are, for example, in
default conditions, the velocity response curve
passes from Normal to Hard.
3.
Press the DATA – and the value will decrease from
3 to 2, therefore the response curve passes back
from Hard to Normal.
4.
Press DATA – again to decrease the value from 2 to
1 to select the Soft response curve.
These settings remain in memory even after turning off, or until
changed again.
Reset
At any moment, you can carry out a reset operation to restore the default
velocity response curve.
5.
Press both Data +/– buttons at the same time to
reset to the Normal (2) response curve.
10
Tune
The TUNE function allows you fine tune the instrument through a range of
values between 428 Hz and 452 Hz. This allows you to instantly adapt the
GRPT140 to almost any performance situation, such as is frequently required
when playing together with other instruments (violin, flute, etc.), or when
accompanying a solo singer. The instrument powers up to the standard setting
corresponding to the equal tuning A = 440 Hz.
To modify the tuning
Tuning is a global parameter, meaning that the setting affects the instrument
as a whole (all the instrument’s sounds). The DATA +/– buttons can fine tune
the instrument through steps of 1 Hz at a time.
1.
Select the Tune menu with the Edit knob
The display will show the current default setting of 440 (Hertz).
2.
Press the DATA+ button to increase the frequency
setting, or the DATA- button to decrease the frequency.
Each change of setting is shown in the display as a numerical value
(expressed in Hertz).
At any moment, you can restore the standard pitch of the instrument (A
= 440), by pressing both the DATA+/- buttons at the same time (reset).
The modified tuning value is automatically retained in memory until
changed again, or until the instrument is turned off.
Reset
At any moment, you can carry out a reset operation to restore the
instrument’s standard pitch (A = 440 Hz).
3.
Press both Data +/– buttons at the same time to
reset to the standard tune setting (A = 440).
11
Transpose
This parameter allows you to transpose the instrument’s pitch in steps of one
semitone up or down, over a maximum excursion of +/- 12 semitones.
This allows you to instantly adapt the GRPT140 to almost any performance
situation, such as is frequently required when playing together with other
instruments (violin, flute, etc.), or when accompanying a solo singer.
The instrument powers up to the standard pitch Transpose = 0 (C = C).
The Transposer is a global parameter, meaning that the setting affects the
instrument as a whole (all the instrument’s sounds).
To transpose the instrument
1.
Select the Transpose menu with the Edit knob.
The display will show the current default setting 00 C = C.
2.
Press the DATA+ button to raise the pitch of the
instrument by one semitone, or the DATA- button to
lower the pitch by one semitone.
Each change of setting is shown in the display as a numerical value.
The modified transpose setting is automatically retained in memory
until changed again, or until the instrument is turned off.
Reset
At any moment, you can carry out a reset operation to restore the
instrument’s standard pitch (C = C).
3.
Press both Data +/– buttons at the same time to
reset to the standard tune setting (C = C).
12
MIDI/DEMO
This menu allows you to select the MIDI transmission and reception channel
for the GRPT140 (channels 1 - 16).
The instrument receives and transmits on MIDI channel 1 by default.
This menu also gains access to the demonstration songs (DEMO) of the
instrument (explained on page 6).
Midi is a global parameter, meaning that the setting affects the instrument as
a whole (all the instrument’s sounds).
Changing the Midi channel
1.
Select the Midi\Demo menu with the Edit knob
The display will show the current default setting 1.
2.
Pressing the DATA+ button increases the MIDI
channel setting by one unit at a time; 2, 3, etc.
Each change of setting is shown in the display as a numerical value.
3.
Pressing the DATA- button decreases the MIDI
channel setting by one unit at a time.
Using this procedure, you can set the preferred MIDI channel setting for
the instrument.
The modified MIDI channel setting is automatically retained in memory
even after turning the instrument off, or until changed again.

About MIDI
MIDI, the abbreviation for “Musical Instrument Digital Interface”, is a world
standard interface that allows MIDI compatible instruments and other equipment to communicate with each other in order to exchange data and control
one another.
MIDI is now a very common feature and a great deal of literature is available
explaining all the standards implemented by MIDI. You are recommended to
consult other specialized literature if you wish to know more about the
standards implemented and how to apply them.
This section limits itself to explain the simplest forms of MIDI applications
for your GRPT140.
The MIDI ports
The GRPT140 module under the keyboard on the left of the instrument has
three MIDI ports: IN, THRU and OUT.
The MIDI IN port receives MIDI data from an external MIDI device which
can be used to control the GRPT140.
The MIDI OUT port transmits MIDI data generated by the GRPT140 (for
example, note or velocity data generated by the playing keyboard).
The MIDI THRU port retransmits the same data received at MIDI IN, and is
useful to connect several MIDI instruments in series.
MIDI channels
The “MIDI channels” used in the MIDI communication system is similar to
television broadcasting. Each channel can receive a different stream of data
with respect to the others.
Exactly as occurs in television broadcasts, in order to exchange data, the
receiving and transmitting devices must be tuned correctly. In other words,
the MIDI controlling device and the MIDI receiving device must both be set
to the same MIDI channel, selected from the 16 possible channels available.
Multiple channel instruments, called multi-timbral units, can receive and
transmit across several different MIDI channels at the same time, but each part
must correspond to the same MIDI channel between the two communicating
units.
GRPT140 is able to receive and transmit on one MIDI channel only. In this
situation, if GRPT140 receives MIDI information from a multi-timbral
controlling device, it will only respond to the data travelling on the same
channel as the GRPT140 reception channel, while the data travelling on other
channels will be ignored.
The default MIDI reception/transmission channel setting of GRPT140 is
channel 1. You can set any channel from 1…16. Whatever MIDI channel you
decide to set will remain memorized until changed again, or until you turn the
instrument off then on again.
14
MIDI messages transmitted and received by
GRPT140
GRPT140 transmits and receives the following type of MIDI information.
Note and Velocity information
This is information pertaining to the note played and relative velocity value.
The receiving device recognizes the note because it is defined by the “MIDI
note number”, and the velocity value is defined by the “MIDI velocity value”.
Whenever a key on the GRPT140 is pressed, the note and velocity information is transmitted from the instrument’s MIDI OUT port to the receiving
device. Conversely, GRPT140 will play the corresponding notes whenever
note and velocity data is received at the instrument’s MIDI IN port.
Program Change numbers
This type of information relates to data which identifies the sounds contained
in the GRPT140 memory. GRPT140 transmits MIDI Program Change
numbers from 0 - 63, corresponding to the 5 panel Sounds and 59 User Sounds
that can be selected from the command module. Whenever a Sound is
selected, the corresponding MIDI Program Change number is transmitted to
the receiving device, causing the correspondingly numbered voice to be
selected in the external MIDI unit. Conversely, whenever GRPT140 receives
a Program Change number (0-63) from an external MIDI device, the correspondingly numbered GRPT140 Sound will be automatically selected.
Control Change numbers
The Soft and Damper pedals of GRPT140 generate Control Change data
(Soft: CC 67, Sostenuto: CC 66, Damper: CC 64) which is transmitted from
the instrument’s MIDI Out port whenever the pedals are operated.
The internal tone generator of the receiving device will respond to the pedal
solicitations in the same way as the GRPT140 Sound engine. Whenever the
same type of Control Change data is received by GRPT140, it will respond
appropriately.
MIDI Applications
The following explains how your GRPT140 can be used in the most common
MIDI setups suited to this instrument:
a) as a MIDI controlling device (Master);
b) as a tone generator (in other words, a Slave);
c) for MIDI sequence recording.
As a MIDI controlling device
GRPT140, like most MIDI instruments, transmits note and
velocity information (touch response) via the MIDI OUT
port whenever notes are played on the keyboard.
If the MIDI OUT port is connected to the MIDI IN port of
another MIDI keyboard (synthesizer, etc.) or a tone generator (more commonly called an “expander”, but essentially
any device with an internal sound engine), the external unit
will respond precisely to the notes played on the transmitting keyboard.
MIDI Out
GRPT140
MIDI In
Expander
15
The result is that such a setup allows you to play two instruments at the same
time, using GRPT140 as the controlling device (Master) and the other as the
device being controlled (Slave).
Quite simply, every time you select a Sound, you will send a Program change
message to the external device who will respond by playing a second sound.
As a Slave device
As well as transmitting MIDI information, GRPT140
recognizes the same type of data if received at the MIDI IN
port from an external Controlling device. In this case, the
MIDI IN port of the GRPT140 is connected to the MIDI
OUT port of the external controlling unit. This allows
GRPT140 to be controlled in exactly the same manner as
described above, only this time, the GRPT140 behaves as
the slave and the external device the controller.

Midi Sequencer recording
MIDI keyboard
The type of data transfer described above can be exploited very efficiently for
MIDI sequence recording. For this connection, shown in the diagram, the
RPT115’s MIDI OUT is connected to the Sequencer MIDI IN, and the
Sequencer MIDI OUT is connected to the RPT115’s MIDI IN. This
connection is more commonly know as a “MIDI Loop”.
Any instrument with a sequencer, or a Computer running
sequencer software, can be used to capture (record) the
MIDI data transmitted by the GRPT140.
MIDI Out
MIDI In
MIDI Out
When the recorded data is played back, the GRPT140
reproduces the recorded sequence in exactly the same
manner as it was recorded.
MIDI In
GRPT140
Sequencer
The MIDI THRU port
To connect more than one slave device to a master controlling device, you can
use the MIDI THRU port.
For example, to connect both the GRPT140 as well as an
expander to a sequencer, connect the RPT115’s MIDI IN to
the MIDI OUT of the sequencer, and the RPT115’s MIDI
THRU to the expander’s MIDI IN.
If GRPT140 is set to receive on MIDI Channel 1, you can
program the expander to receive on channel 2 (or 3). In this
way, the sequencer can transmit one set of data to the
GRPT140 (on channel 1) and a different set to the expander
(on channel 2 or 3).
