After Later Audio QARV // The Ultimate Manual, Walkthrough & Patch Tips

All patches shown in this video can be found in my supplemental Illustrated Patch Guide/Manual: https://drive.google.com/file/d/1TmgB...

In this video we take a deep dive into QARV by After Later Audio. QARV is a 20hp Quad Attack Release VCA, function generator, mixer, oscillator, LFO, envelope generator, filter, recifier, and overall mega utility.

Module Overview:

Each channel has a signal input and trigger input, looping attack/release cycles from audio level (VCO) to LFO cycles as long as 7+ hours. The attack/release has shaping from exponential to linear to logarithmic and can attenuate or invert with the OUT attenuator. Attack/Release have CV control as well as CH.2 & 3 having an inverted BOTH input for Attack and Release control similar to 1v/oct tracking. Channels 1 and 2 have Rise and Fall gates that are high whenever the signal is in their respective Attack (Rise)/Release (Fall) state.

Each OUT signal is internally routed to control the CV for it's VCA, and each channel's VCA input is the signal input
(You can treat the VCA input as the CV and the internally routed signal as your signal for half wave rectification).

Channels 1 and 4 also have a constant voltage switch for 5 and 10 volts so you can set any discrete voltage within that range (positive or negative). Also use this with a signal input to offset your voltage.

And don't be shy with self-patching, QARV likes to play with itself!
