Oscillator ugens

Basic Oscillators

Phasor

simple ramp generator ( 0 to 1 ) this can be fed into other oscillators ( with sync mode of 2 ) as a phase control. see examples/sixty.ck for an example

• .freq  (float, READ/WRITE)  oscillator frequency (Hz)
• .sfreq  (float, READ/WRITE)  oscillator frequency (Hz), phase-matched
• .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
• .phase  (float, READ/WRITE)  current phase
• .sync  (int, READ/WRITE) (0) sync frequency to input, (1) sync phase to input, (2) fm synth

SinOsc s => dac;

440 => s.freq;

1::second => now;

see examples/osc.ck
