Appendix E: MIDI Implementation
The Prophet X receives MIDI data according to the settings you have
chosen in globals. In addition, there is interaction between some of the
program parameters that determine the overall response of Prophet X
to MIDI data. These are the globals parameters that affect response to
MIDI:
MIDI Channel: All, 1…16—Selects which MIDI channel to send and
receive data, 1 to 16. All receives on all 16 channels.
MIDI Clock Mode: Sets the Prophet X’s ability to send and receive MIDI
clock messages:
• Off: MIDI Clock is neither sent nor received
• Master: MIDI Clock is sent, but not received
• Slave: MIDI Clock is received, but not sent
• Slave Thru: MIDI Clock is received and passed to MIDI Out
• Slave No S/S (no start and stop): Receives MIDI Clock but does not
respond to MIDI Start or Stop command.
When set to slave or slave thru, if no MIDI clock is present at the selected input,
the arpeggiator and sequencer will not function.
MIDI Clock Cable: MIDI Port, USB—Sets the port, MIDI or USB, by
which MIDI clock signals are received.
MIDI Param Send: Off, CC, NRPN—Changes to the values of front panel
controls are transmitted via MIDI as Continuous Controllers (CC) or
Non-Registered Parameter Number (NRPN). Transmission of parameters
can also be turned off.
NRPNs are the preferred method of parameter transmission, since they cover
the complete range of all parameters, while CCs are limited to a range of 128.
MIDI Param Receive: Off, CC, NRPN—Sets the method by which parameter
changes are received via MIDI. As with transmission, NRPNs are the preferred
method.
