  • .phase  (float, READ/WRITE)  current phase
  • .sync  (int, READ/WRITE)  (0) sync frequency to input, (1) sync phase to input, (2) fm synth
  • .width  (float, READ/WRITE)  set duration of the ramp in each cycle. (default 1.0)

 

SinOsc

sine wave oscillator

  • .freq  (float, READ/WRITE)  oscillator frequency (Hz)
  • .sfreq  (float, READ/WRITE)  oscillator frequency (Hz), phase-matched

SinOsc s => dac;

440 => s.freq;

1::second => now;
