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.
