MIDI to more accurate CV

I calibrated the pitch CV on my MCVI MIDI to CV module. McGovern’s software takes notes in the range A1 to C8, the range of a standard 88 note keyboard, and maps them to 0 to 4095 mV output from the MCP4822 12-bit DAC. Then this voltage is amplified by 1.77 to go from 0 […]

1106 all posh

I’ve built my MCVI MIDI to CV synth module, the one I breadboarded here. It handles a range of 88 MIDI notes, corresponding to a standard piano keyboard, using a 12 bit DAC. CV output is 0 V (for MIDI note 21, A0) to +7.25 V (MIDI note 88, C8). Note selection in case of […]

Known to its friends as 1106

Kosmodrome will need a MIDI to CV module — something that’ll listen to a MIDI keyboard or other MIDI source and convert note on/off messages into pitch and velocity CVs and gates. And other things: Pitch bend messages and modulation wheel messages to CVs, clock messages to clock pulses, things like that. There’s already a […]
