#X text 348 118 The phasor~ object outputs a sawtooth signal \, traditionally used for table lookup via cos~ or tabread4~. If no argument is supplied \, the input is taken to be an audio signal \; with a floating-point argument \, phasor~ takes floating-point messages to change frequency.;
#X text 294 246 Invoked above with argument for non-signal input. Incoming messages override the initial value.;
