hey japina, you should probably try to get familiar with the composition operators (:, <:, :>, ~, etc.) to get a deep understanding of how these things are built up. especially the recursive operator can be a bit tricky to understand, but is very enlightening when you finally wrap your head around it. based on the faust manuals chapter around the modulo primitive (https://faust.grame.fr/doc/manual/index.html#modulo-primitive <https://faust.grame.fr/doc/manual/index.html#modulo-primitive>), this could probably deliver what you are after:
cycle(N) = _~+(1) : -(1) : %(N); process = select2(cycle(200) < 100, -1, 1); it recursively adds 1 to a signal, takes the modulo of 200 of it so it is counting infinitely from 0 to 199. then it outputs -1 if the signal is below 100 and 1 otherwise. hope this helps best josh > On 9.
