Prophet 12 Operation Manual
Global Settings
6. 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.
7. MIDI Control Enable: Off, On—When On, the synth will respond to 
MIDI controllers, including Pitch Wheel, Mod Wheel, Pedal, Breath, 
Volume, and Expression.
8. MIDI Sysex Enable: Off, On—When On, the synth will respond to 
received MIDI SysEx messages, and will transmit them, when prompted, 
to the MIDI Out. See Sysex Messages on page 82 for details.
9. MIDI Sysex Cable: None, MIDI Port, USB—Sets the port, MIDI or 
USB, by which System Exclusive data will be transmitted and received.
10. MIDI Out Select: Off, MIDI, USB, MIDI+USB—Sets the port by which 
MIDI data will be transmitted.
11. Local Control: Off, On—When on (the default), the keyboard and 
front panel controls directly affect the Prophet 12. When off, the controls 
are transmitted via MIDI but do not directly affect the “local” synth (that 
is, the Prophet 12). This is primarily useful for avoiding MIDI data loops 
that can occur with some external sequencers.
12. Mono/Stereo: Stereo, Mono—The Prophet 12 defaults to stereo 
operation. When set to Mono, this parameter defeats all pan settings and 
modulation, effectively making each of the outputs a mono output.
13. Pot Mode: Relative, Passthru, Jump—The rotary controls on the 
Prophet 12’s front panel are a mixture of “endless” rotary encoders and 
potentiometers or “pots.” The pots are identiable by their lined knobs 
and the fact that they have about 300° of travel. There are three pot 
modes to determine how the synth reacts when the programmable param-
eters are edited. (Master volume is not programmable, so these modes 
don’t apply.)
When set to Relative, changes are relative to the stored setting. In Rela-
tive mode, the full value range is not available until either the minimum 
or maximum value and the respective lower or upper limit of the pot’s 
travel is reached.
