Chapter 4: Using the Pro 3 with
External Devices
This chapter explains how to use the Pro 3 to process external audio, how to
synchronize the Pro 3’s Sequencer to an external MIDI device, and how
to use the Pro 3 with a modular synthesizer.
Processing External Audio
The Pro 3 makes a great effects processor. The example below shows
you how connect external audio to the Pro 3 and process it in real time by
tweaking knobs and controls.
To hear an external audio signal, you need to gate the amplier and lter open.
When you do this, you will also hear the Pro 3’s oscillators droning since they’re
continuously producing sound. To avoid continuous oscillator drone, set the level of all
oscillators to zero in the Mixer.
To process external audio:
1. Connect an instrument or audio signal to the audio in jack on the rear of
the Pro 3 and turn up the instrument to a suitable level.
2. Press the hold button then play a key on the keyboard. This holds the
VCA open.
3. To avoid continuous oscillator drone, set the level of all oscillators to
zero in the Mixer.
4. Turn up the ext audio knob in the Mixer section of the Pro 3. (If you
need to further boost the signal, adjust input level and input gain.
When you adjust the ext audio knob in the mixer, these controls appear
in the display.
5. Turn the sustain knob on the amplier envelope to 127.
6. Turn the sustain knob on the lter envelope to 127.
7. Play the external audio source.
8. Tweak parameters such as lter cutoff, distortion, drive, tuned feed-
back, effects, and so on to process the sound.
