correspondingly numbered voice to be selected in the external MIDI unit.
Conversely, whenever RPT114 receives a Program Change number (0-7)
from an external MIDI device, the correspondingly numbered RPT114 Sound
will be automatically selected.
Control Change numbers
The Soft, Sostenuto and Damper pedals of RPT114 generate Control Change
data (CC67, CC66, CC64) 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 RPT114 Sound engine. Whenever the
same type of Control Change data is received by RPT114, it will respond
appropriately.
MIDI Applications
The following explains how your RPT114 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
RPT114, like most MIDI instruments, transmits note and velocity informa-
tion (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 genera-
tor (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 transmit-
ting keyboard.
The result is that such a setup allows you to play two instruments at the same
time, using RPT114 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, RPT114 recog-
nizes 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 RPT114 is connected to the MIDI OUT port
of the external controlling unit. This, therefore, allows
RPT114 to be controlled in exactly the same manner as
described above, only this time, the RPT114 behaves as the
slave and the external device the controller.
