MCM-100 in rack

This 12hp wide module is designed to allow you to plug in your MIDI input and get going quickly. Designed for simplicity and ease of use with a good amount of customizability. It features a 1v/octave note output, velocity CV output, and assignable aux and control CV outputs. There are also full gate (note on), trigger (note start), and MIDI clock sync +5v pulse outputs.

Features

  • Single or omni MIDI channel input
  • MIDI input via USB or standard 5-pin MIDI cable
    • Note that early versions do not have an external USB jack, however you can still attach a USB cable to the module and route the cable as you see fit.
  • Four CV outputs for note (1v/oct), velocity, aux and control selectable 0 to +10v or 0 to +5v
    • 1v/octave through 10 octaves (at 0 to +10v), or 5 octaves (at 0 to +5v)
  • Gate, trigger, and clock full 0 to +5v pulse outputs
  • Selectable note priority (last, highest, lowest)
  • Tuneable pitch and velocity adjust
  • Customizable trigger output duration pulse width
  • Pitch bend response range from 0 to 5 octaves
  • Full display of output states
  • Built in tuning and calibration setup
  • Settings persist to on-board flash ROM
  • Designed to fit in 12hp, 3U module
  • Skiff-friendly, about 30mm depth
  • Power Draw:
    • +5v: 70mA
    • +12v: 20mA
    • -12v: 15mA

Responds to the following MIDI messages:

  • Note on / off: sends/stops the note and velocity outputs
    • For +10v output, responds to C-1 (note number 0) to B9 (note number 119)
    • For +5v output, responds to C2 (middle-C, note number 36) to B6 (note number 95)
    • Sends a trigger pulse on note on, and turns on the gate for the duration of the note
  • Volume: increases or decreases the velocity CV output
  • Pitch bend: modifies any currently playing note. Adjustable range from 0 to 5 octaves
  • Sustain: holds a note on while the sustain is active
  • Aftertouch: selectable as an aux output
  • Expression: selectable as a aux output
  • Mod wheel: selectable as a control output
  • Effect 1: selectable as a control output
  • Effect 2: selectable as a control output
  • Mute (all notes off): clears any note, velocity, and gate outputs
  • Clock tick: MIDI clock ticks are sent directly to the clock output
  • Reset: reset the MIDI input messaging queue and stops any output

Customizable Features

  • Midi channel
  • Note priority
  • Pitch and velocity adjustment
  • Pitch bend range
  • Aux and control output selections
  • Trigger duration
  • Output voltage settings per CV out (+10v / +5v)
