self oscillation.then sweeping cutoff till you find note....Is it Beating ??
On a synth...when resonance is turned all the way up into self oscillation and you sweep the cutoff till you match the pitch...something starts to happen to the sound as you are close on both sides of the note..and it changes the rate as u move around right next to it...what is this called ?
Is it called Beating ??
what is amplitude modulation then ?
Thanks
