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! For a manual please visit the Sound Study Modular website. Compatibility: 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 MIDI clock output 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: 220O (rule of thumb: 2 cents drop per connection to a CV input) Power supply: - USB-bus powered, current draw <20mA
