Hi guys, I was looking at chuck manual, talking about LFO and then FM came to my mind. But...How? I was thinking to a very simple FM like this: 1) SinOsc alpha carrier 2) SinOsc beta modulator 3) SinOsc gamma beta's amplitude modulator So i thought something like this SinOsc alpha => dac; SinOsc beta => blackhole; SinOsc gamma => blackhole; then oscillators frequencies 220 => alpha.freq; 4 => gamma.freq; while (20::ms => now ) { (gamma.last () ) + 2 => beta.freq; in this way I've got my amplitude modulation on beta. Then I have to Beta.freq + alpha.freq => alpha.freq - Frequencies sum. - } This is just an idea..... Could it work ? And how can I make beta and alpha's sum? May I have to use fun like fun void ( int freqalpha, int freqbeta ) or something like this? Thankssssss
