After Later Audio released QARV

Posted on by

After Later Audio released QARV (Quad Attack, Release, and VCA), a new module for eurorack. Four channels of function generator, oscillator, slew limiter, envelope, and VCAs.  This module brings the ultimate in flexibility as it can be used as a standalone synth voice, a massive amount of modulation, or a four channel envelope generator w/ mixer.  We believe this makes QARV a great first module and a great addition to the largest of systems.

All four channels have the following features:

  • Uni-polar oscillator mode
  • Attack and release time control via potentiometer and via input jack
  • Shape control that controls shape for both attack and release
  • Output attenuverter
  • VCAs that normal to each subsequent channel (CH1 -> CH2, etc.).  So you can get a mix of all four channels out of the CH4 VCA output (unless you patch a VCA output from an earlier channel)

Channels 1 & 4

  • Voltage source (CH1 – 5V & CH4 – 10V)
  • CH1 & CH4 can be switched between IN (slew mode) and TRIG (envelope) mode
  • RISE and FALL gates.  You can use our G&T module to turn these gates into triggers.
  • Cycle times 50sec – 1kHz (0.5ms)

Channels 2 & 3:

  • Bi-polar oscillator mode
  • Dedicated IN and TRIG jacks (helpful for adding offset to a triggered ENV)
  • BOTH input jack to simplify patching both the attack and release (also inverts the input to give more standard pitch tracking of higher voltage equals higher pitch)
  • Cycle times 200sec – 1kHz (0.5ms)
