[sc-dev] Ugen creation q

[Casey Basichis <caseybasichis@xxxxxxxxx>]

Here are some questions in going through LFPulse, I
also looked at Latch which was clear.
Thanks,
Casey

//phase goes between 0 and 1?

^this.multiNew('audio', freq, iphase, width).madd(mul,
add)
// This copies, the arguments to the variables in the
structure?


void LFPulse_next_a(LFPulse *unit, int inNumSamples)
{
	float *out = ZOUT(0); 
	float *freq = ZIN(0); // Not sure what this does
	float nextDuty = ZIN0(2); // Not sure what this does
				  // ZIN0 means only get at each buffer?
	float duty = unit->mDuty;	
	float freqmul = unit->mFreqMul;
	float phase = unit->mPhase;
	LOOP(inNumSamples, 
		float z;
		if (phase >= 1.f) {
			phase -= 1.f; // Keeps the phase in a 0-1 range?
			duty = unit->mDuty = nextDuty; // nextDuty, ZIN?
			// output at least one sample from the opposite
polarity
			z = duty < 0.5 ? 1.f : 0.f; // This i dont get.
Why?
		} else {
			z = phase < duty ? 1.f : 0.f; // I get this.
		}
		phase += ZXP(freq) * freqmul; // increment freq
(ZIN)
					      // (whatever that is) multiply by
					      // frequency add to phase?
		ZXP(out) = z;
	);

	unit->mPhase = phase;
}
