Mutable Instruments CVpal (Usb/cv Eurorack)

Connect your computer or iPad/iPhone (with camera connection kit) to your modular system.

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 usual 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.

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.
