Chapter 4: Using the Pro 3 with External Devices
Sequential
Using Pro 3’s CV Outs to Control a Modular Synth
The Pro 3 can interface with modular synthesizers through its four
control voltage inputs and outputs. This makes it possible to use the Pro 3
as the central hub of a modular system.
For example, you could play the modular synth’s oscillators from the Pro 3
keyboard. Y ou could also use the Pro 3’s Sequencer to modulate the external
modular synth’s lters. You could even use the Pro 3’s Touch slider and
Mod Wheel to perform real-time modulation of the modular synth. The
possibilities are extensive.
In the example below, the Pro 3 keyboard is used to play the oscillator of
a modular synth.
To use the Pro 3’s CV Outs to control the oscillator of a modular synth:
1. Using a 3.5 mm patch cable, connect the Pro 3’s CV Out 1 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. On the Pro 3, press the source button in the modulation section.
3. Using Soft Knob 1, choose an available mod slot.
4. Using Soft Knob 2, select note number number as the mod source.
5. Using Soft Knob 4, select cv 1 out as the mod destination.
6. Using Soft Knob 3, set the mod amount to 127. (Anything less than
this will affect pitch scaling.)
7. Play the Pro 3 keyboard. The modular synth’s oscillator should respond
to the notes. (You may need to tune the modular synth’s oscillators to
match the Pro 3’s oscillators.)
Use the same basic procedure to route modulation sources such as
Sequencer tracks, the touch slider, the mod wheel, and so on, to the modular synth.
In this way you can use the Pro 3 as the central controller for a larger modular system.
