Hi! I am building a synth with pd and want to use a triangle wave oscillator with symmetry modulation. I know how to make a triangle wave oscillator:

phasor~ cliped~ at 0.5 multiplied by two and substracted by the original phasor signal

but i cannot figure how to change its symmetry without using an infinite variable to get a perfect sawtooth waveshape.

Make it an imperfect sawtooth, then. It will sound very digital anyhow, due to the aliasing you introduce by a perfect sawtooth.

If someone could help me, i would want an explanation for doing that oscillator. I am not an engineer, so a mathematical equation would not help me a lot. Thanks for any help. Dany Lebel
