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! Compatilitiby 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. Conversion modes Monophonic with velocity Monophonic with velocity and square oscillator Dual monophonic Duophonic CC conversion Monophonic with CC Quad triggers Quad gates Monophonic CVCVpalpalwith 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.
