A Few Tutorials
The Pro 2 is a very deep instrument with virtually endless sonic possibilities.
Though step-by-step tutorials for all of its capabilities are outside the
scope of this manual, this chapter provides a few short tutorials to help
you explore some key features.
Processing External Audio
The Pro 2 makes a great effects processor. The example below shows
you how connect external audio to the Pro 2 and process it in real time by
tweaking knobs and controls.
To hear an external audio signal, you need to gate the VCA and filter open.
When you do this, you will also hear the Pro 2’s oscillators droning since they are
continuously producing sound. To avoid continuous oscillator drone, set the
output
level
of all oscillators to zero. Alternatively, set the waveshapes of each oscillator to
osc oFF
.
To process external audio:
1. Connect an instrument or audio signal to the
audio in
jack on the rear of
the Pro 2 and turn up the instrument to a suitable level.
2. Adjust the
ext
.
input level
knob in the oscillator section of the Pro 2.
(If you need to further boost the signal, adjust
ext
.
in gain
(soft knob 2
in the display).
3. Press the
hold
button then play a key on the keyboard. This holds the
VCA open.
4. Turn the
SuStain
knob on the amplifier envelope to 127.
5. Turn the
SuStain
knob on the filter envelope to 127.
6. Play the external audio source.
7. Tweak parameters such as filter cutoff, distortion, drive, hack, feed-
back, delay (particularly the
time
parameter of delay 4!), and so on to
process the sound.
Connect an expression pedal to the Pro 2 and route it to a parameter such as filter
cutoff in the mod matrix for more real-time processing control over the audio input.
