achieving audio-rate amplitude modulation w EFM

Colin Muir Dorward	Posted on Fri 19 Jan 2024, 01:08 AM Lets say I wanted a sine wave to be amplitude-modulated by another sine wave; pitches of both are tracking the keyboard. Is there FM-wizardry that can achieve this? Thinking maybe there is a solution using two OPs in parallel with detune... but can't think it through clearly

If I wanted a sinewave amplitute modulated by a 10hz, waveform, I would place two sine operators in parallel and detune one by 10hz. AFAIK the resultant waveform is a sinewave "beating" at 10hz, which is not unlike AMing a sine by a 10hz sine. That's as far as I can get 😂 You can also use looping envelopes to do a kind of AM, with lots of amazing sound design opportunities there ! But again it's quite crude, and keytracking the env segment length is not really effective.
