Description
Features:
- Voltage Controlled Amplifier (VCA): Two summing inputs allow for control from multiple sources, including audio frequencies for AM effects. An “Instant On” button sets the control to full-on somewhat independent of the input control voltages. The first input (CV1) has gain sensitivity and offset, but the 2nd does not.
- Function Generator: Based on the XR2206, both a triangle and square wave output are available from 1Hz to 100Hz. Changing the timing cap on the 2206 circuit will allow for different ranges. The Triangle wave has a Wiggle and Wobble knob that affect it’s magnitude and offset. These adjustments let you push the wave up against its limits to produce a triangle with flattened tops and bottoms. The shape approahces that of a square wave with an adjustable duty cycle. The signal can be used to go from a subtle tremolo effect to an abrupt chopping one.
- Attack / Release Envelope Shaper: This lets you add a ramp to the onset and release of a square gate signal. The circuit is ultra simple, and consists of two caps, two potentiometers and two diodes.
- Effects that can be applied to audio: Tremelo, chopping, note shaping with AR gen, AM (amplitude modulation).
