of 16 Drumkits. Another drumkit is also in Bank 4.
These sounds and sound banks can only be selected via MIDI, not from the
RP60/70 control panel. To select these sounds via MIDI, you would have to
send a Midi message to the RP60/70 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 RP60/70
RP60/70 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 RP60/70 is pressed, the note and
velocity information is transmitted from the instrument’s MIDI OUT port to the
receiving device. Conversely, RP60/70 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 RP60/70 Preset. RP60/70 transmits MIDI Program Change
numbers from 1 - 32, corresponding to the 32 Presets that can be selected from
the panel. Whenever you select a Preset, the corresponding MIDI Program
Change number is transmitted to the receiving device, causing the corre-
spondingly numbered voices to be selected in the external MIDI unit, set to
receive on the same MIDI channel as the RP60/70.
Conversely, whenever RP60/70 receives Program Change number data (for
1-32) from an external MIDI device, the correspondingly numbered RP60/70
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 RP60/70
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
RP60/70 Sound engine. Whenever the same type of Control Change data is
received by RP60/70, it will respond appropriately.
