Chapter 4: Using CVs and Gates
6. Send a “C” from the controlling device, corresponding in pitch to the
low C note on the Prophet-10’s keyboard.
7. Use the group select (decrement) and bank select (increment)
switches to make negative or positive adjustments to the CV In Low
Point, bringing the Prophet-10’s pitch to “C”. The Prophet-10’s CV
Input is quantized to semitones, so the pitch will jump abruptly as you
make the adjustment, rather than change gradually.
8. Press program select button 4 to begin adjusting the CV In High Point.
9. Repeat steps 5-7. The target pitch for the CV Out High Point is “C”
ve octaves above the Low Point pitch.
10. Press program select button 8 to exit CV Calibration Mode.
Using Prophet-10’s Gate In and Gate Out
The Prophet-10 can interface with a gear that accepts gate in or gate out
signals for envelope triggering.
Note that Prophet-10 Gate Out signals are output from the Prophet-10
keyboard each time a key is pressed. Note also that when a jack is
inserted into the Prophet-10’s rear-panel gate in jack, voice 5 is no
longer available to play from the keyboard and will instead be triggered
by the external gate signal.
The Prophet-10’s gate in is tolerant of voltages up to 15v, but any posi-
tive voltage above 1.7v will gate its envelopes.
To use the Prophet-10’s Gate Out:
1. Using a ¼ inch patch cable, connect the Prophet-10’s Gate Out to the
appropriate Gate In on the external device
2. Play the Prophet-10 keyboard. The external device should respond to
the Prophet-10 envelope triggers each time you strike a key.
To use the Prophet-10’s Gate In:
1. Using a ¼ inch patch cable, connect the Prophet-10’s Gate In to the
appropriate Gate Out on the external device.
2. Play the external device. The Prophet-10 should respond to the Gate
signal of the external device. As noted above, voice 5 is no longer
available to play from the keyboard and will instead be triggered by the
external gate signal.
