Been having making presets for the DM12 (full bank to come in the final version) and starting to get some FM tones which it definitely wasn’t designed for. It’s not an FM based synth nor are DCOs known for anything to do with FM but there’s still some cool overtones to be had playing with mod matrix to create some FM. I’m using the LFO at audio rate which also track note number to create the overtones and keep them musical across the keyboard.
