I'm building a subtractive synth. Each 'oscillator' has an adjustable waveform and I'm doing this by cross-fading between saw~ tri~ rect~ signals, with these objects all being driven by the same frequency signal. I have some questions about doing this:
(1) Is it possible that saw~ tri~ and rect~ could drift out of phase, even if they are driven by the same frequency signal, as in the left-hand arrangement in the attached patch?
(2) If this is possible that they could drift out of phase, they can be kept in phase using the arrangement in the right hand part of the attached patch. As far as I can see, this has no adverse affect on the output waveform but am I correct? Is this a good way to keep them in phase?
