FM on NerdSEQ: Is it FM or PM? - mgd - 03-12-2021
In the process of becoming more familiar with NerdSEQ's FM engine I would like to understand whether it is FM or actually PM (phase modulation).
The difference as far as I understand it is this:
PM(t) = a*sin( f * t + b * sin(f' * t))
FM(t) = a*sin( (f + b * sin(f' * t)) * t)
For two operators this is pretty much the same but it will become different with three or more operators in a row.
Just curious
Kind regards,
Michael

It is FM, though I am not calculating every sample like this.
