SteveD Posted January 15, 2013 Report Share Posted January 15, 2013 Hi all,I'm using the Papilio Pro/Retrocade hardware in a slightly different way. I am attempting to replicate a Minimoog synth using DSP techniques. The source code is available at https://github.com/sjdavies/minimoog. So far the system does the following:1) performs digital->analog conversion using a 12 bit delta-sigma DAC (as per Xilinx doco).2) generates a sawtooth/square/pulse waveform for a given MIDI note number.3) samples all 16 analog port pins, latching each value in distributed RAM. Not much but it's a start. Next tasks:1) clean up the clock logic2) get a MIDI keyboard attached and working. Enjoy,Steve Link to comment Share on other sites More sharing options...
