Appendix E: MIDI Implementation
The Prophet Rev2 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 Rev2
to MIDI data. Following 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 Rev2’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.
Param Rcv:
Off, CC, NRPN—
Sets the method by which parameter changes
are received via MIDI. As with transmission, NRPNs are the preferred method.
MIDI Prog Enable:
Off, On—
When set to On, the synth will respond to
MIDI controllers, including pitch wheel, mod wheel, pedal, and volume.
MIDI SysEx Cable:
MIDI, USB—
When set to MIDI it will receive
and transmit them using the MIDI ports/cables When set to USB it
will receive and transmit them using the USB port/cable. MIDI SysEx
messages are used when sending and receiving a variety of data includ-
ing, programs, alternative tunings, system updates, and more.
MIDI Out Select:
MIDI, USB—
Sets the port by which MIDI data will be
transmitted.
