Re: Writing Efficient Code

Be aware, when creating parallel UGens with loops, of units that are
doing the same thing. Those could be created outside the loop and
shared across all the downstream units.

// inefficient: 5 SinOscs that will produce the exact same signal

SynthDef(\chainedDelays, { |delayFreq = 0.15, delayCtr = 0.05,
delayMod = 0.03, out = 0|
        var sig = In.ar(out, 2),
                new = sig;
        5.do {
                new = DelayL.ar(new, 0.1, SinOsc.kr(delayFreq, 0, delayMod, delayCtr));
        };
        Out.ar(out, sig);
});

// better:

SynthDef(\chainedDelays, { |delayFreq = 0.15, delayCtr = 0.05,
delayMod = 0.03, out = 0|
        var sig = In.ar(out, 2),
                delayTime = SinOsc.kr(delayFreq, 0, delayMod, delayCtr),
                new = sig;
        5.do {
                new = DelayL.ar(new, 0.1, delayTime);
        };
        Out.ar(out, sig);
});

This kind of inefficiency is really easy to overlook.

PS Am I the only person who trims old replies from the e-mail? Some
messages get really huge just because of quoted material that doesn't
add anything to the discussion. (Speaking of efficiency...!)
