I'm very new to pd, having just installed it to see if I could use it to create a synth I have already designed.
At the heart of the synth is a pair of sync oscillators. So, to recreate it, I'll need to be able to reset an oscillator to the beginning of its cycle every time a master oscillator crosses zero.
After searching, I read a couple old posts dealing with generally ineffective ways to detect zero crossings, and then chanced upon a post that mentions [zerox~]. Apparently, it detects all zero crossings (2 per cycle of a sine wave) and there is no help file to speak of.
Does anyone have any experience with this object? I'm interested in knowing if it is practical for audio-rate detection.
I'll be doing some experiments of my own, which will progress slowly as I familiarize myself with pd.
