• 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 :-)
.. and a version 1.5 corrects a mistake in the input calibration description and eases the reading elsewhere.
