Using the Pro 2’s CV Outs to Control a Modular Synth
The Pro 2 can easily interface with modular synths through its four
control voltage inputs and outputs. This makes it possible to use the Pro 2
as the central hub of a modular system.
For example, you could play the modular synth’s oscillators from the
Pro 2 keyboard. You could also use the Pro 2’s sequencer to modulate
the external synth’s filters. You could even use the Pro 2’s position- and
pressure-sensitive sliders to perform real-time modulation of the modular
synth. The possibilities are extensive.
In the example below, the Pro 2 keyboard is used to play an oscillator on
a modular synth.
To use the Pro 2’s CV Outs to control the oscillator of a modular synth:
1. Using a ⅛ inch patch cable, connect the Pro 2’s CV Out 1 to the
appropriate CV In on the modular synth’s oscillator module. (The input
should support a 1-volt-per-octave signal.)
2. On the Pro 2, press the
aSSign Source
button in the Mod 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
ext cv out
1 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 2 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 2’s oscillators.)
Use the same basic procedure to route modulation sources such as sequencer
tracks, the touch sliders, the mod wheel, and so on, to the modular synth. In this way
you can use the Pro 2 as the central controller for a larger modular system.
