[sdiy] FPGA based synthesizer progress....

[Thomas Laskowski]

Wow, sounds neat.  When I tried to make a synth on an FPGA I managed to get two oscillators going controlled through the serial port.  I think I got the routines for the serial port (and the 1-bit DAC) on fpga4fun.  Look around there if you haven't.  You're making good progress already.  Obviously I was learning and didn't know much of what I was doing.  I read on how the SID oscillators worked and modeled it after those.  But that's not very efficient way of doing things.  I am looking forward to seeing more progress.  Are you doing it in Verilog?
