Specifications

MIDI interface and MIDI event processor with 4 CV outputs and 4 Trigger/Gate outputs.

Conversion modes

  • Monophonic with note, velocity, modulation wheel, auxiliary CC/aftertouch CV.
  • 2-voice polyphonic or 2-part multitimbral with two note CV and auxiliary CC/aftertouch CV.
  • 4-voice polyphonic or 4-part multitimbral with four note CV.
  • 4-part trigger conversion with MIDI note selection for each part.
  • Clock/reset output in monophonic, duophonic, or trigger conversion modes.
  • Polychaining mode handling half of the notes internally and forwarding the other half to the MIDI out.

MIDI processing

  • Transposition.
  • Split/keyboard ranges.
  • Multiple voice allocation schemes in polyphonic mode (voice-stealing, random, cyclic).
  • Multiple note priority modes in monophonic mode (lowest, highest, latest).
  • Arpeggiator with up/down/up&down/random/chord/”as played” modes and 22 preset patterns.
  • 64-note SH-101 style sequencer per part.
  • Euclidean pattern generator.

Conversion

  • 1 V/oct and 5V Gate/Trigger standard.
  • Micro-tunings (through MIDI tuning messages).
  • Just intonation.
  • Portamento, pitch-bend and modulation wheel (vibrato).
  • Audio output mode replacing the note CV by a digital oscillator offering sine, square, pulse, triangle, sawtooth or noise waveforms.

Technical characteristics

  • 8kHz CV refresh rate, 48kHz refresh rate in audio mode.
  • High-end 16-bit DAC and voltage references.
  • 12-point calibration table, adjusted in factory.
  • 8 memory slots for storing/recalling all settings and sequences.
  • Cortex-M3 ARM processor guaranteeing blazingly fast response to MIDI messages, even with a full stack of arpeggiators and sequencers running.
  • Open-source hardware and firmware.
  • 12-HP.
  • Easy firmware updates through MIDI (SysEx).
  • Current consumption: +12V: 60mA ; -12V: 2mA.
