Generalmusic GEM pRP8 Owner's Manual page 25

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 pRP8 control panel. To select these sounds via MIDI, you would
have to send a Midi message to the pRP8 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 pRP8
pRP8 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 pRP8 is
pressed, the note and velocity information is transmitted from the
instrument's MIDI OUT port to the receiving device. Conversely, pRP8
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 pRP8 Preset. pRP8 transmits MIDI Program
Change numbers from 0 - 63, corresponding to the 64 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 pRP8.
Conversely, whenever pRP8 receives Program Change number data
(for 0-63) from an external MIDI device, the correspondingly numbered
pRP8 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 pRP8
generate Control Change data which is transmitted from the instru-
ment's MIDI Out port whenever the pedals are operated. The internal
tone generator of the receiving device will respond to the pedal solicita-
tions in the same way as the pRP8 Sound engine. Whenever the same
type of Control Change data is received by pRP8, it will respond
appropriately.
