Expert Sleepers General CV

General MIDI synthesizer and CV-to-MIDI powerhouse for Eurorack

12 HP Eurorack module

The General CV is a Eurorack module combining a powerful General MIDI synthesizer, a multichannel CV-to-MIDI converter, and a host processor capable of generating rich MIDI data from incoming control voltages or algorithmically. It offers modes ranging from simple CV-to-MIDI conversion and VCO emulation to chord generation, arpeggiators, drum triggering, and MIDI file playback, giving a modular system access to the full palette of 128 General MIDI sounds with stereo audio output.

  • Preset save/load to/from MicroSD card
  • 5 rotary encoders with push-button function
  • OLED display with overview, menu, parameter edit, and mode-specific views
  • Auto-blank display for extended display lifetime

Controls & Jacks (16)

  • Encoder B— Adjust parameter, advance to next parameter page, scroll through pages when held
  • R Output— Stereo audio output (right channel) from the General MIDI synthesizer, approximately +/-8V.
  • Encoder D— Multi-function encoder D. Adjusts parameters, displays mode-specific information when pressed.
  • Encoder E— Multi-function encoder E. Adjusts parameters for the fifth channel or function group.
  • Input 6— High-resolution bipolar CV input +/-5V (14-bit). Function depends on mode: quantizer key, key, speed, etc.
  • L Output— Stereo audio output (left channel) from the General MIDI synthesizer, approximately +/-8V.
  • Input 4— High-resolution bipolar CV input +/-5V (14-bit). Function depends on mode: pitch (1V/oct), file select, etc.
  • Encoder C— Multi-function encoder C. Adjusts parameters, returns to first parameter page when pressed.
  • Encoder A— Multi-function encoder A. Navigates menu system and adjusts parameters. Functions vary by mode (General MIDI program select, wavetable posit
  • Input 5— High-resolution bipolar CV input +/-5V (14-bit). Function depends on mode: velocity, speed (exponential), etc.
  • Input 3— Analog CV input 0-5V (10-bit). Function depends on mode: reverb send, chorus send, scale, etc.
  • X Input— Digital input jack X. Functions as gate, clock, or trigger depending on the selected mode.
  • Input 7— Analog CV input 0-5V (10-bit). Function depends on mode: program select, drum, gate, etc.
  • Input 2— Analog CV input 0-5V (10-bit). Function depends on mode: modulation wheel, reverb send, arp mode, etc.
  • Y Input— Digital input jack Y. Functions as sustain pedal, retrigger, or reset depending on mode.
  • I Input— Digital input jack I. Functions as MIDI input for receiving external MIDI data.
