Does anyone know of a tutorial or object that deals with waveforms intrepolation ( for instance the outcoming wave of a cycle~ with that of a saw~ )?
Thanks

Coralie

This may not give you what you’re looking for in terms of morphing, however. What’s the effect that you’re looking to create?

I’m using a saw as an lfo that is modulated by an adsr, but I’d like to be able to make the wave shape change to get different kinds of pulses. I find the pulse of the lfo very sharp, I’d like to get something smoother. But maybe I’m completely wrong about this. Actually your solution seems to correspond, but I indeed think that the morphing will not be very convincing. So my idea is maybe not very good.

in case you also want to display the waveform it is getting more work.

That’s a different story, since you don’t need to worry about antialiasing. My recommendation: use triangle~. With a value of 1 in the right inlet, it will be a sawtooth. As you interpolate between the two waveforms’ amplitude, also sweep (using line~) the right inlet of triangle~ from 1 to 0.5. That way the waveform will transition towards the center as it turns into the sine.

I’ll probably post the result. Thanks a lot!
