Chapter 4: Using CVs and Gates

This chapter explains how to connect the Prophet-10’s Control Voltage inputs

and outputs and Gate in and out

to external devices such as a modular

synthesizer.

Using Prophet-10’s CV Out

The Prophet-10 can interface with a modular synthesizer and other

devices with control voltage ins and outs through its CV input and

output

In the example below, the Prophet-10 keyboard is used to play

the oscillator of a modular synth. Note that CV output tracks the last note

played on the Prophet-10.

To use the Prophet-10’s CV Outs to control the oscillator of a modular

synth:

1. Using a ¼ inch patch cable, connect the Prophet-10’s CV Out to the

appropriate CV In on the modular synth’s oscillator module. (The

modular synth’s input should support a 1-volt-per-octave signal.)

2. Play the Prophet-10 keyboard. The modular synth’s oscillator should

respond to the notes. (You may need to tune the modular synth’s oscil-

lators to match the Prophet-10’s oscillators.)

Adjusting the Prophet-10’s CV Output Scaling:

The Prophet-10 is calibrated at the factory so that low C on the keyboard

produces 0v at the CV Out and high C produces 5v. Depending on the

device you wish to control using the Prophet-10’s CV Out, you may need

to make slight adjustments to these voltages in order for the target device

to track pitch accurately across the full range of the Prophet-10 keyboard.

Adjusting CV Output scaling:

1. Connect the Prophet-10’s CV Out to the CV In of an external oscillator

or synthesizer using a standard ¼ inch TS patch cable.

2. Connect the Prophet-10’s gate out to the Gate In of the same device

using a standard ¼ inch TS patch cable.

3. Enter CV Calibration Mode by holding down the globals switch and

pressing program select button 5.
