PLAYING VOLTAGE CONTROLLED SYNTHESIZERS

The Revolution provides a CV (control voltage) output, along with a Gate output for playing pre-

MIDI and modular synthesizers. The CV the Revolution generates is the most widely used 1 volt

per octave standard. The Gate signal the Revolution generates is a positive polarity type gate ranging

from 0 volts (note off) to +12 volts (note on). This standard was used on the early Roland, Arp, and

Sequential Circuits analog synthesizers, and is still used by today’s modular s

ynthesizer companies to

control their devices.

As a general rule, always turn the power off for devices when making connections.

For this setup, first connect the CV OUT of the Revolution to the CV INPUT of the external analog

device using a 1/4” mono cable. You will also need to connect the GATE OUT of the Revolution to“

the GATE INPUT of the external device using another 1/4” mono cable.

Most analog synthesizers will automatically use these external signals to control their circuits once

they are plugged into the unit. If your device requires you to setup parameters in that module to use

these external control signals, do that now.

Start playback of the Revolution’s sequencer and you should hear the notes programmed into the

sequencer playing the external module. You’re free to select and edit different patterns within the

Revolution as you normally would. Accents programmed into the sequencer will have no affect on

the external analog sound module. Notes that are programmed to glide in the sequencer

will cause the

CV output to slew which will sound just like a note gliding in the Revolution’s analog sound section.

You can also sync the Revolution’s playback to an external MIDI clock while playing the external

analog module.

Notice that if you set th

e Revolution’s MIDI mode to EXTernal, as you would to play the

Revolution’s sound section with an external MIDI keyboard or sequencer, you can then convert these

external MIDI messages into the appropriate CV/Gate signals needed to control the connected analog

module. This is similar to what a standalone MIDI to CV converter does.
