Math
Rounds a value upward to the next integer. For example 2.1 becomes 3, while -2.1 becomes -2. This is useful for stepped modulation, harmonic selection, and quantized pattern logic.
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.
