Additional Technical Information:
The DXJFC communicates to the DX amplifier via MIDI (Musical Instrument
Digital Interface). Communication is on MIDI channel 0 by default, since the DX
amplifier operates in “omni/poly” mode.
Presets are changed by standard MIDI program change messages. The MIDI
message value can range from 0 to 9.
The Tap function defaults to MIDI controller #80. Value decimal 127 (hex 7F)
is sent when the tap is pressed, zero is sent when it is released.
The expression pedal defaults to controller #11 using single byte controller val-
ues. Pedal assignments are communicated to the DX amplifier via a MIDI “sys-
tem exclusive” (aka sysex) message. The following chart shows the sysex mes-
sage format (in hexidecimal) after the System Exclusive status byte.
