Among the basic waveforms (sine, saw etc.) I found something that's called 'sync saw' in my synth. If anyone knows what this is, I'd like to have some details. (This isn't very important but I'm just eager to find out how things work.)
It has just one adjustable parameter which is 'sync off' and units are in 1/2 tones. As a default its value is 0 and it sounds just like a normal saw wave. When the value is increased, you'll hear something similiar to flanger or something until it reaches first even harmonic (1 octave or 12 1/2 tones). Then it sounds again just like a regular saw except as if it was transposed 1 octave higher. When further increased you'll hear again some weird flanger-ish things until it reaches the next even harmonic. Then the same thing happens again. It sounds normal but its pitch is equal to second even harmonic. And it keeps going like that.
Any ideas?
