#P comment 213 456 314 196617 a >~ object works quite nicely as a square or pulse wave oscillator.;
#P comment 213 182 314 196617 this patch uses a signal-and-hold object (sah~) to generate an offset signal that gets added with the output of the phasor~. when the modulation signal passes through zero in a positive direction \, sah~ samples the value of the ramp \, and holds it constant until the next trigger. the signal is inverted and summed with the ramp. as a result \, the ramp resets to zero at the instantaneous moment that it is sampled by sah~.;
#P comment 169 64 313 196617 <-make a zero-to-one transition with the checkbox to "re-start" the slow phasor~ ramp.;
#P comment 213 31 100 196620 oscillator sync;
#P comment 213 352 314 196617 the resulting ramp signal can be used to drive anything \, in msp. the typical subject in analog synthesizers is a pulse wave oscillator \, which yields a pretty familiar sound... other types of oscillators \, wavetable lookup synthesis \, and buffer~ scanning are all interesting. as well \, the modulating sync signal does not need to be a stable oscillator - although \, harmonically simple signals often seem to work best. networks of basic oscillator types can be tuned to complex relationships \, that evolve slowly...;
#P comment 213 273 314 196617 it is then necessary to pong~ the value - not only so that it stays within the bounds of 0-1 \, but also so that it remains a continuous ramp \, for the purposes of driving an oscillator or other synchronized process. the integrity of the ramp can be verified by observing the patch at sub-audio rates \, as in the example to the left \, or by displaying high frequency behavior with scope~.;
#P comment 213 115 314 196617 the basic idea is to use the output of one oscillator to re-start another - a standard technique on analog synthesizers. in msp \, it is possible to analyze any signal \, in any number of ways \, and use the result to modulate an oscillator - but first we need to figure out how to re-trigger a ramp signal with sample-accurate response.;
