[sdiy] Some Music

[Eric Brombaugh]

Great stuff Scott - thanks for sharing it!

It's amazing how much good sound you can get out of a couple of 12-bit 
DACs when they're used carefully. Building your own instrument up from 
raw gates gives a great deal of control

Question about how you did this: are you playing live with a keyboard, 
or are you driving the FPGA designs from a MIDI sequencer/recorder?
