This kit contains everything you need to build the module - components, PCBs, and the front panel.

Control your analogue Eurorack modules via MIDI! This module comprises 4 1V/Oct CV outputs, 4 analogue velocity outputs, 4 gate outputs, plus one bonus digital square wave voice.

• 12HP wide
• 40mm deep including the power plug (Skiff friendly)
• can control 4 voices - with 1V/Oct, velocity, and a gate to trigger envelopes etc
• assign each voice to any MIDI channel
• or, choose one of the 3 polyphonic modes - Sequential, Overlap or Unison
• Unison is also really useful to tune all your oscillators to one another
• configure how many polyphonic voices to use - for instance, if you only have 2 oscillators, you can play polyphonically on just 2 channels
• use the Tone output to assist tuning your analogue oscillators
• can be accurately calibrated to +-0.001V

To calibrate this module, you should ideally use a voltmeter accurate to 3 decimal places up to 6V. Building the module will be easier if you have 2 long breadboards, because you can use these to keep the pin headers straight as you solder them.
