[sdiy] PIC Wavetable OSC Timing

[William Berzinskas]

Hey everyone.. 

I've made a simple wavetable oscillator..  it's got an r-2r ladder and 64 position waves..  works pretty good for the basic stuff i've got..  got a few waveforms in there.. nothing special, just the standard tri/saw/square for testing..

can someone explain to me how to setup the timing to be controllable via midi..  

if i understand correctly, the midi note number would somehow set the reset point on a timer..  the timer would interrupt at a specified freq, and output the bits..   

assuming i've got that lil theory-ish part right, how to implement it?
