Oscillator / Waveshaper
Random value generator. Use it for irregular modulation or noisy decisions; scale it down when controlling pitch or filter frequency.
Use moderate values first, then increase modulation depth while listening for clipping, aliasing, or excessive filter resonance.
0.02*rnd()*sin(X)
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.
