Oscillators

Threshold: 0…127—

(In the

ext

input

tab in the OLED display) Sets the

threshold above which external input signals will trigger the Pro 2’s Gate

and envelope follower. Triggering these from an external input allows

you to drive the Pro 2’s envelopes, sequencer steps, and more with

guitars, drum machines and so on.

Oscillator 1 Sub Octave: 0…127—

(In the

Sub

oSc

tab) Controls the

level of a sine wave oscillator pitched one octave below oscillator 1.

Because a sine wave has few harmonics and is mainly characterized by

its fundamental frequency, adding a sub octave to sounds such as bass are

a great way to increase their low-register presence.

paraphonic program.

(Envelope Follower) Attack: 0…127—

(In the

parameter by turning the

oSc

Sub

octave

knob. Sets the attack speed of

the envelope follower.

(Envelope Follower) Release: 0…127—

(In the

Sub

tab) Access this

parameter by turning the

oSc

Sub

octave

knob. Sets the release speed of

the envelope follower.

Sync: Off, On

—Turns oscillator hard sync on. Sync utilizes pairs of

oscillators to force one oscillator (the slave) to restart its cycle every time

the other oscillator (the master) starts a cycle. This provides a way to

create more complex, harmonically rich shapes from simple waveforms.
