Morphing between classical waveforms has a flavor of PWM.

Hello Gang,

Well it’s been a stretch, 27 tries to get all 4 shapes and it’s still not perfect, but still good and usable. With one knob or modulation, it goes from a Triangle wave to a Sine wave to a Square wave and last to a Saw wave. One problem or benefit, is the knob or modulation if changed too fast the shape of the Saw wave is odd or even doubled. Like I said though this can of course sometimes be a benefit as you still get most of the Saw waves particles or a good second harmonic. A second problem is under ADSR control there is some glitching at times that as yet I have NOT been able to resolve if at all possible. Still I would really appreciate it if someone or someone’s look it over and can see where there could be improvements. Any way please enjoy and do post some comments.

Later then, BobF…..

Here is my Triangle > Sine > Square morpher that I use. It's not anti-aliased so I wouldn't use it for oscillators, but they are great for LFO use.

Thank you Adam,

Very cool! By any chance do you have a version in "DSP code", I can understand it, but Assembly NOT at all.

Take care, BobF.....

Unfortunately no, I wrote it directly in assembler
