Programmable Volt/Octave CV calibrator and transposer

  • Four V/Oct processing channels, each with

    • Curve correction and range expansion for any VCO, VCF or other oscillating circuit with a CV acting on the pitch
    • Switchable semitone quantizer
    • Adjustable portamento time
    • Adjustable glissando time
  • Separate semitone and octave transpose encoders
  • Inputs cascading with no added load for stable pitch control
  • Four user presets storing transpose, portamento, and glissando
  • Storage of the calibration profile for each channel
  • Maximum voltage range covering 10 octaves
  • Presets, calibration and current state retained over power cycle
  • Volt/Oct inputs factory-calibrated in flash memory
  • Easy firmware update via a simple audio file
  • High-quality push-encoders with metal shaft
  • Skiff-friendly & compact module

Firmware 1.17 offers:
* User editable input scaling to match sources that don't generate perfect 1V per octave signals.
* Complete rewrite of the main processing with higher precision.
* ... and the unavoidable fixes and tweaks ;-)

The updated user manual 1.4 is much expanded with operations described in exquisite details :-)
