Math
Rounds a value downward to the previous integer. For example 2.9 becomes 2, while -2.1 becomes -3. It is useful for quantizers, stepped modulation, and phase wrapping tricks.
Use moderate values first, then increase modulation depth while listening for clipping, aliasing, or excessive filter resonance.

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.
