Sound Study - MIDI 2 CV

A clone of the Mutable Instruments CV PAL.

The Sound Study Modular Midi 2 CV is a 4hp USB MIDI to CV and Gate converter. It has a bunch of different modes that it can operate on, like monophonic, duo monophonic, and many more!


The Midi 2 CV is class-compliant but uses an unusual USB setting (1ms poll-rate in low-speed mode) not well supported on Windows.

Optimal latency is obtained with OS X >= 10.6.3 ; iOS ; or Linux >= 2.6.

On other systems, the Midi 2 CV will work but messages will be delayed by up to 8ms.

Technical characteristics

Range and standards:

CV outputs: 0 to 4V, V/Oct (4 octaves).
Gate outputs: Positive V-trig, ON = 5V ; OFF = 0V.

Resolution: < 2mV.
8 points calibration curve for non-linearity compensation.
Temperature dependency: +/- 2 cents within the 10° C to 80° C range.
Output impedance: 220Ω (rule of thumb: 2 cents drop per connection to a CV input).
Power supply:

USB-bus powered, current draw < 20mA, no Eurorack power connector required

  • Module does not draw current
  • 42 mm deep

Available as an assembled Module and as a DIY project.

This Module is currently available.
