I am using the el.oscil~ for my oscillator needs(thanks for the great tools Mr. Eric!). When I modulate phase with another oscillator, an artifact noise comes in to play, this does not happen if I use cycle~.

Why does this happen, and is there a solution to this?

Sorry your message arrived empty. A forum bug I guess?

maybe the waveforms are not anti aliased?

Hmm they are sinewaves but I am not sure about the theory behind it. As far as I know, cycle~ uses a lookup table and I am not sure if it does anything to prevent aliasing(and it makes no noise).

But yes it surely sounds like an aliasing problem to me.

Just asking.

Send the message "interpolate 1" to both oscil~ units and this will clean up the mess. By default oscil~ is non-interpolating which is cheaper on the CPU but, as you discovered less pristine.

Thank you very much, it works smoothly now!
