    Hello Keith. Omnichord Om-27. I don't have sound in my headphones. I use Ableton 12. Ableton, lets me record, but I don't get sound in my headphones. I use a Scarlett 2i2. And... I hear some white noise(buzz). Why does that happen? And I don't know how to listen to music created in Ableton either Thanks

    This is the best (maybe only) strategic approach to FM synthesis that I have seen. Your approach creates a framework for development of any sound.

    Loved your video, great quality and detail. I too was curious about how the breath sensor worked, I've read about it on the service manual, but the description's drawing is "a bit" misleading (maybe they wanted to prevent others from copying it..), but the actual implementation is SO simple, it's basically a membrane microphone used as a pressure/deformation sensor. Also from reading the manual, I imagined it should present some kind of bouncing from the mechanical parts, and there it was: I could see the voltage dips below the resting value when you showed the staccatos. Once again, bravo and thank you for such a great video!

    • @krmelectronics

    THANK YOU. I'm currently writing a manual for a DAW and was baffled by the FM in a synth in it because I've pretty much only had experience with linear FM and had absolutely no idea what it was doing. It is INSANE that I've never heard of this distinction in FM types before. There seems to be shockingly little discussion about it online.
