Hallo, guillaume rabusseau hat gesagt: // guillaume rabusseau wrote:

I want to make an oscillator giving a triangle signal with shape modulation, i.e. i want to go from a signal like |||\ to a signal like /|/|/| passing by a common triangle (///). I've found a tricky solution (i've joined the patch) but i'm not really happy with that because it makes a strange shape with very "hard" harmonics (instead of a triangle (going up and down smoothy) i have a jump into...)

I'm not sure this is really clear, i hope the patch will be more precise...

Probably, but it's missing. ;)

Anyway, J05.triangle.pd shows an example for how to make triangle waves with variable duty cycles. A longer explanation is in The Book: http://crca.ucsd.edu/~msp/techniques/latest/book-html/node199.html
