Channel Controls

The Quadrangle has four channels. Each one looks like this:

A: CV over Attack

● CV control over the Attack cycle of the envelope. The input signal is additive and

subtractive to to the physical position of the potentiometer.

D/R: CV over Decay/Release

● CV control over the Decay cycle of the envelope. The input signal mimics the pot range

and is additive and subtractive to to the physical position of the potentiometer.

EOA: End of Attack trigger output

● Sends a trigger when the envelope has completed the Attack portion of the cycle.

EOC: End of Cycle trigger output

● Sends a trigger when the envelope has completed its cycle.

ATTACK

● Sets the length of the Attack cycle. Minimum: ~2ms. Maximum: ~2 seconds.

DEC/REL: Decay/Release

● Sets the length of the Decay cycle. Minimum: ~2ms. Maximum: ~2 seconds.

LEVEL

● Controls the output voltage of the envelope, with a range of -5V to +5V. At 12:00, the

envelope sends zero volts. When turned fully toward the - symbol, it sends 0 to -5V.
When turned fully toward the + symbol, it sends 0 to +5V.
