Math
Modulo/remainder function. It returns what is left after division and is useful for repeating time windows, looped positions, and rhythmic pattern math.
Use moderate values first, then increase modulation depth while listening for clipping, aliasing, or excessive filter resonance.
mod(pos(), 22050)
For pitched oscillator functions, X already contains the current MIDI note pitch and transpose information. Prefer saw(X), sin(X), or pwm(X, 0.4) unless you intentionally want an octave or ratio shift such as 0.5*X or 2*X.
