The XM8 just made its first ever sound - controlled by midi from a little phatty to the XM8 Voice controller, through the OMM and on through SPI to the DCO. Playing worked like a charm - pitch changes are delayed but that is to be expected since the SPI speed is set to a minimum right now. I had a lockup too, somewhere in the Voice controller code, but all in all I'm really pleased!
The tracking is awfull, I think I've used different intervals for semitones in the Voice controller code and the DCO, but it is very clearly playing semitones.
Woohooo! Videos to come.
