Mutable Instruments CVPAL Eurorack USB MIDI to CV Module

Simple yet effective USB Midi to CV Converter, best used with a computer!

The CVpal features a large palette of control modes – monophonic with velocity and extra square oscillator, monophonic with clock outputs, duophonic, dual monophonic, or even quad trigger conversion! Its 12-bit DAC with an 8-point software calibration curve makes it more accurate than more expensive products.

• Plenty of modes (mono CV/Gate/Velocity/Square digital oscillator ; duophonic and dual channel modes ; 4 note trigger conversion ; CC to CV conversion…)
• Digital calibration provides better accuracy than offset/scale trimmers
• USB-powered
• Gates are +5V  CV’s are +4V
• 1ms latency on OS X and Linux, 8ms latency in Windows
• 40 mm Depth

Compatibility

The CVpal 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 CVpal will work but messages will be delayed by up to 8ms.

Conversion modes

• Monophonic with velocity
• Monophonic with velocity and square oscillator
• Dual monophonic
• Duophonic
• CC conversion
• Monophonic with CC
• Quad triggers
• Quad gates
• Monophonic with MIDI clock output

Technical characteristics

Range and standards:

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

Performance:

• 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.

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
