OSC 3 Amplitude Modulation (OSC 3 > AM) - Switch on to use Oscillator 3 as an amplitude modulation of the other 2 oscillators.

How to make this? any ideas?

Hi DJ, Don't have much time, and some other folks are helping with your other posts - but here is some quick help for the AM before I have to go out.

AM is just using an amp (or multiply = the same thing) to make one oscillator 'wobble' the volume of another (So for you, osc 3 'wobbles' osc2 and osc1).

Tricky bit is to make the 'wobble' have the right numbers - so you see in the picture I have "AM Maths" modules to make the numbers right. Here is that little module...

With this "AM Maths" module, you do not need switches - to turn it off, just move the knob to zero (they are just normal knob that go from 0 to 1).

I checked it on the analyser. It works as it should do. http://en.wikipedia.org/wiki/Amplitude_modulation On higher frequency it sounds ring-mod like. And when the modulating osc is at a low octave the sound wobbles. I send you the osm back with the analyser connected.

Is this what you wanted to have?

Ok thinks it works now. Thank you all!

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
