Playing the pRP7
Connect the audio cables
The pRP7 does not incorporate an internal amplification system, therefore you must either play using headphones or connect to a suitable
external amplification system.
Connect the audio outputs to your amp. system (mixer, powered
speakers, etc.) using audio cables with standard 1/4” jacks. Use RCA
jacks to connect to domestic stereo units. For mono reproduction,
connect to the Right/M jack.
Headphone jack
If you are not playing connected to an external amplfication system, plug
a set of headphones into the Phones jack to play in total silence without
disturbing others in the same room. Use a mini jack1/4” adapter for
Walkman or MidiDisc headphone sets. The Phones jack is located on
the rear connections panel.
Use the Volume control to adjust the Headphones volume.
Connect the power supply
Connect the Generalmusic power supply unit to the 12V. D.C. jack.
Turn the instrument on
To turn the pRP7 on, press the ON/OFF switch located on the rear
connections panel.
After a short period, the instrument will be ready to play the Grand Piano
preset. The LED of the Grand Piano Preset button will be on and the 3digit LCD display will show a tempo setting as an indication that the
instrument is on.
In this power up condition, you will be able to play a piano sound
(GrandPiano) across the entire keyboard without carrying out other
operations.
LED on
Adjust the overall volume
Use the VOLUME control knob to adjust the overall volume level.
Sliding the VOLUME control knob to the right will increase the overall
volume, while sliding to the left will decrease it.

Play using the Pitch/Modulation Joystick
While you play, you can apply Pitch Bend and Modulation to the Preset
sounds by using the Pitch/Modulation Joystick located on the extreme
left of the control panel.
•To obtain Pitch Bend, move the Joystick Up or Down.
•To obtain Modulation, move the Joystick in Left/Right directions.
Pitch Bend is a “glide” (or glissato) effect which simulates the effect that
certain instruments can produce (trombone, guitar, violin, etc.).
Modulation is an effect which simulates the natural vibrato of such
instruments as the violin, cello, human voice, etc..
Pedal Connection
The pRP7 has two connectors for the connection of optional, switchaction pedals: SOFT and DAMPER.
SOFT: The Soft pedal is a switch control pedal (On/Off) which affects
the timbre of the instrument such that it plays softer, allowing you to
continue using the same playing style at a lower volume.
MODULATION
PITCH BEND
DAMPER: The Damper pedal applies the Sustain effect to all notes
released. 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.

The pRP7 Presets
The pRP7 contains 48 Internal Presets, consisting of Single, Split and
Layered sound combinations. Each sound combination also recalls the
volume levels, a configuration of effects (Reverb and Delay/Modulations) together with relative effect send levels
The Presets are organized in the SELECTION section. The table shown
opposite lists the pRP7 Presets, grouped in sets of six, each group
corresponding to a button of the section.
The Selection buttons
This section consists of a row of 8 Preset “family” Groups.
The 8 Preset Group buttons are marked as follows: Piano, Electric
Piano, Keyboard, Organ, Strings, Choir\Pad, Guitar, Vibes.
Each button of the SELECTION section activates a Bank of 6 Presets.
Using the [–] and [+] buttons of the SOUND VARIATIONS buttons, it is
possible to select the 8 Presets of each bank sequentially. The 8 Presets
of each bank are factory-set to recall Presets configured in the following
manner:
123456
SingleSingleSingleSingleLayerSplit
Each Preset of the current Group contains a memorized Layer and Split
sound combination which you can recall in real time by activating the
LAYER or SPLIT buttons in the CONTROL section accordingly.
Similarly, a Layer or Split Preset is easily converted to one of the other
modes by activating/deactivating the SPLIT or LAYER buttons accordingly.
For example, if you have selected the Layer Preset 5 of a Preset Group,
simply press SPLIT to recall the memorized Split combination, or
deactivate LAYER to recall the memorized Single sound.

The CONTROL section
Realtime operations
The pRP7 operating system has been conceived to permit several
simple and quick real time operations using the buttons of the CONTROL section.
Activate Split mode
Starting from the Single Preset “GrandPiano”, you can easily split the
keyboard by pressing the SPLIT button. This will divide the keyboard
into separate left and right sections.
<------- Ac. Bass ------><--------- GrandPiano ---------->
After pressing the SPLIT button (the LED turns on), the GrandPiano
sound remains active on the right side of the split. An Acoustic Bass
sound is automatically assigned on the left side of the split.
If you press the SPLIT button again, the LED will turn off and the
keyboard returns to the previous mode with the GrandPiano sound
active to play across the entire keyboard.
Change the Split point setting
The default setting of the Split point corresponds to F#3. You can quickly
modify the setting to suit your requirements.
1.Press and hold down the SPLIT button.
The LED of the SPLIT button starts to flash and the display shows
the current split point setting expressed as the MIDI note number
(54 = F#3).
2.While still holding down the SPLIT button, press the note on the keyboard
corresponding to the new split point required (B3 in the example).
Flashing
The new split point is shown in the display as Midi note 59 (B3).
The setting remains memorized for all the Presets. It is not
possible to assign a different Split point setting for each Preset.
10
Activate Layer mode
To mix or “layer” two sounds together, simply press the LAYER button.
After pressing the LAYER button (the LED turns on), a second sound is
activated layered with the first (in this case, Strings is added to the
GrandPiano sound).
If you press the LAYER button again, the LED turns off and the keyboard
returns to the previous mode with the GrandPiano sound active to play
across the entire keyboard.
Add effects to the selected Preset
You can easily add or cancel effects from the current Preset by
activating/deactivating the REVERB and EFFECTS buttons in the
CONTROL section.
The on/off status of these two buttons show whether or not the current
Preset is playing with or without one or both effects. When the LED of
a button is on, the preset is playing with the corresponding effect.
In the following example, the REVERB and EFFECT buttons are both
on, meaning that the current Preset can be played with both effects.
When the LED of a button is off, the Preset can be played without the
corresponding effect (bypass).
In the following example, the REVERB button is off (LED off) and the
EFFECT button is on, meaning that the current Preset can be played with
the recalled Delay/Modulation effect only.
11
Change the Volume Balance between two sounds
If you are playing either in Layer or Split mode, you can regulate the
volume of the two sections in real time using the BALANCE buttons.
These buttons regulate the volume of one section with respect to the
other, creating a perfect balance between the two sections according to
your requirements.
1.Hold down the BALANCE button to increase the volume of the main
sound.
The volume of the main sound will increase while the second
sound (split or layer) will decrease automatically in proportion to
the main one. Release the Balance button when you obtain the
required setting. The 3 digit LCD display will show the current
setting for a short period before returning to the Tempo setting.
2.Conversely, hold down the BALANCE button to increase the volume of
the second sound.
The volume of the second sound will increase while the main
sound will decrease automatically in proportion to the second one.
Release the Balance button when you obtain the required setting.
The display will eventually show a negative value when the level
of the second sound is higher than the main one.
If you select a Single Preset (or deactivate the SPLIT or LAYER
button), the BALANCE buttons operate as normal Volume controls for the main section.
12
Transpose
Pressing either TRANSPOSE button will adjust the pitch of the instrument in half-step (semitone) increments or decrements, through the
overall range of –/+ 12 semitones.
When both LEDs are off, the pitch of the instrument is set to normal
(Equal: C = C).
1.Press the TRANSPOSE # button once to raise the pitch of the instrument.
Play on the keyboard and you will hear that the pitch of the
instrument is raised one semitone. The LCD display shows the
current setting as a relative value, “01”, for a short period before
returning to the tempo setting.
The LED of the TRANSPOSE # button remains on to indicate the
changed status of the pitch. Every time you press the TRANSPOSE # button, the pitch is raised by one semitone.
ii
#
2.Press the TRANSPOSE b button to lower the pitch of the instrument.
Play on the keyboard and you will hear that the pitch of the
instrument is lowered one semitone. The LCD display shows the
current setting as a relative value, “–01” in this case, for a short
period. A negative transposition value indicates that the pitch is
one semitone lower than normal (00).
The LED of the TRANSPOSE b button remains on to indicate the
changed status of the pitch. Every time you press the TRANSPOSE b button, the pitch is lowered by one semitone.
After about 5 seconds, if you fail to press either Transpose button,
the display returns to the previous situation and the instrument
remains at the last set pitch.
The current Transpose setting remains memorized even after
turning the instrument off. When you turn the instrument on again,
the LED of the Transpose buttons will indicate the changed status
of the pitch.

13
Touch
The pRP7 offers three different keyboard responses, or “velocity curves”,
which affect the instrument as a whole. When you turn on the instrument
for the first time, the “NORMAL” curve will be shown set, indicated by the
LED in correspondence to the NORMAL setting of the TOUCH button.
SOFT: This is useful for a player with a lighter touch or somebody
more accustomed to a synth action keyboard. It requires only a
relatively soft touch to achieve maximum volume.
NORMAL: This setting most accurately represents the touch
response of a piano.
HARD: This setting is for “stronger” players. It requires a fairly
powerful touch to achieve maximum volume.
The various curves can be selected by repeatedly pressing the TOUCH
button.
The selection of the Touch curves is cyclic; starting from Normal,
pressing TOUCH once selects HARD, followed by SOFT, then back to
NORMAL, and so on....
The selected response curve remains in memory even after turning the
instrument off. When you turn on again, you will be able to see at a
glance what the current Touch setting is by looking at the status of the
LED.
14
The Functions of the pRP7
pRP7 features 4 functions which affect the instrument in various ways.
The Functions are activated using the last 4 notes of the highest octave

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 give some
examples regarding the simplest forms of MIDI applications for your
pRP7.
The MIDI ports
The pRP7 is fitted with two MIDI ports: MIDI IN and MIDI OUT.
The MIDI IN port receives MIDI data from an external MIDI device which
can be used to control the pRP7.
The MIDI OUT port transmits MIDI data generated by the pRP7 (for
example, note or velocity data generated by playing the keyboard).
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 16 possible channels.
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. pRP7 is able to transmit on up to three MIDI
channels. In reception, pRP7 can be used as a multi-timbral unit,
because it can receive MIDI on 16 channels.
Midi Common
If you set pRP7 to receive MIDI messages on the Common channel, all
program change messages received by pRP7 are interpreted as Preset
Change messages, allowing you to play the 48 Presets from the external
keyboard which emulates the pRP7 internal keyboard. Simply set the
external controlling device to transmit MIDI messages on the same
channel as the pRP7 Common channel (16).
The pRP7 MIDI Sounds and Banks
Via MIDI, your pRP7 offers some interesting features which cannot be
achieved using the instrument on its own. On its own, the maximum
number of Presets you can select on pRP7 are those listed on page 6,
a total of 48, some of which recall single sounds, some two layered
sounds across the keyboard and others two or three sounds on a split
keyboard.
When you use pRP7 as a slave device, a MIDI controller keyboard can
play the pRP7 internal Midi sounds which are organized in four banks,
20
the first three housing 128 sounds organized in “family” groups, and the
fourth containing 60 sounds. The bank 1 sounds correspond to the
industry standard General MIDI sound library, while banks 2 and 3
contain sounds taken from Generalmusic’s own extensive sound library.
Bank 4 contains an additional 60 Sounds, but not organized in “family”
Groups like those in banks 1, 2 & 3. Banks 2 and 3 also contain a
Percussive family where you’ll find a selection of 16 Drumkits. Another
drumkit is also in Bank 4.
These sounds and sound banks can only be selected via MIDI, not from
the pRP7 control panel. To select these sounds via MIDI, you would
have to send a Midi message to the pRP7 consisting of two parts:
ControlChange/Bank Select (CC00-BankSelect) followed by a Program
Change (PC). Refer to the Midi sound tables in the Appendix for
information regarding the Banks and Program Change numbers of all
the sounds and Drumkits.
MIDI messages transmitted and received by pRP7
pRP7 transmits and receives the following type of MIDI information.
Note and Velocity data: 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 pRP7 is
pressed, the note and velocity information is transmitted from the
instrument’s MIDI OUT port to the receiving device. Conversely, pRP7
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 pRP7 Preset. pRP7 transmits MIDI Program
Change numbers from 0 - 47, corresponding to the 48 Presets that can
be selected from the panel. Whenever you select a Preset, the
corresponding MIDI Program Change numbers are transmitted to the
receiving device, causing the correspondingly numbered voices to be
selected in the external MIDI unit, set to receive on the same MIDI
channels as the pRP7.
Conversely, whenever pRP7 receives Program Change number data
(for 0-47) from an external MIDI device, the correspondingly numbered
pRP7 Preset will be automatically selected, but only if received on the
Common channel, otherwise, the internal Midi Sounds will be selected.
Control Change messages: The Soft and Damper pedals of the pRP7
generate Control Change data 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 pRP7 Sound engine. Whenever the same
type of Control Change data is received by pRP7, it will respond
appropriately.

MIDI Applications
The following explains how your pRP7 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
pRP7, 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.
The result is that such a setup allows you to play two instruments at the
same time, using pRP7 as the controlling device (Master) and the other
as the device being controlled (Slave).
Quite simply, every time you select a Preset, you will send Program
change messages to the external device who will respond by playing a
second sound.
As a Slave device
As well as transmitting MIDI information, pRP7 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 pRP7 is connected to the MIDI OUT port of
the external controlling unit. This, therefore, allows pRP7
to be controlled in exactly the same manner as described
above, only this time, the pRP7 behaves as the slave and
the external device the controller.
Midi Sequencer recording
The type of data transfer described above can be exploited
very efficiently for MIDI sequence recording. For this
connection, shown in the diagram, the pRP7 MIDI OUT is
connected to the Sequencer MIDI IN, and the Sequencer
MIDI OUT is connected to the pRP7 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 pRP7.
When the recorded data is played back, the pRP7 reproduces the
recorded sequence in exactly the same manner as it was recorded.
22
Recording Studio
The pRP7 features a simple but powerful sequencer which allows you
to accurately record your playing or create simple songs. This section
takes a closer look at the controls and related functions.
The Recording Studio, located on the extreme right of the control panel,
consists of four buttons: Play\Stop, Rec, Click and Song Library.
Play/Stop :Starts and stops either playback or recording.
Rec (Record) :Activates “Record pending” mode.

Technology
The pRP7 features a unique application of sound design technology patented by Generalmusic as “Damper
Physical Model”.
Damper Physical Model
The damper pedal accurately simulates the effect of the dampers being moved closer to or further away from the
strings of the piano. Because of this, effects such as partial or half damping can be achieved. The dampers can
even be slowly “squeezed” back against the strings. When the damper pedal (optional) is depressed, the damper
physical model will simulate the effect of sympathetic resonances being produced by the un-damped strings. Even
if you are using a standard switch type pedal, you can hear the effect of the Damper Physical Model by comparing
the sounds of notes played in the highest octave of the instrument with and without the damper pedal depressed.
Note: The Damper Physical Model is applied to the Grand Piano sound only.
