Chapter 4: Using CVs and Gates

This chapter explains how to connect the Prophet-5's Control Voltage inputs
and outputs and Gate in and out to external devices such as a modular
synthesizer.

Using Prophet-5's CV Out

The Prophet-5 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-5 keyboard is used to play the oscillator of
a modular synth. Note that CV output tracks the last note played on the
Prophet-5.
To use the Prophet-5's CV Outs to control the oscillator of a modular
synth:
1. Using a ¼ inch patch cable, connect the Prophet-5'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-5 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-5's oscillators.)

Adjusting the Prophet-5's CV Output Scaling:

The Prophet-5 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-5'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-5 keyboard.
Adjusting CV Output scaling:
1. Connect the Prophet-5'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-5's
using a standard ¼ inch TS patch cable.
3. Enter CV Calibration Mode by holding down the
