我很迷惑。在这段代码中:
SynthDef(\acid,
{
|out, gate = 1, freq, myParam, amp, cutoff, resonance, filtEnvAmt|
var env, audio, filtEnv;
if (myParam == \something, { freq = 200; });
env = Linen.kr(gate, 0, 1, 0, doneAction: 2);
audio = LFSaw.ar(freq, mul: amp);
filtEnv = Line.kr(midicps(cutoff + filtEnvAmt), midicps(cutoff), 0.2);
audio = RLPFD.ar(audio, ffreq: filtEnv + MouseX.kr(0, 5000), res: MouseY.kr(0, 1), dist: 0);
Out.ar(out, audio * env);
}
).add;
b = Pbind(*[
out: 0,
instrument: \acid,
stepsPerOctave: 19,
scale: [0, 3, 5, 8, 11, 14, 17],
octave: 3,
degree: Pseq([0, \, 3, 3, 4, 4, 9, 4, 4]),
myParam: \something,
//prevFreq: Pseq([0, 0, 0, 0, 9, 0, 0, 0, 0]),
dur: Pseq([0.4, 0.4, 0.1, 0.1, 0.1, 0.1, 0.2, 0.1, 0.1]),
cutoff: Pseq([60, \, 50, 60, 80, 60, 90, 80, 50]),
filtEnvAmt: Pseq([20, \, 20, 20, 20, 20, -10, 20, 20]),
resonance: Pseq([0.5, \, 0.5, 0.5, 0.5, 0.5, 0.3, 0.5, 0.5])
]);
b.play;
..平等测试myParam == \something
永远不会返回true,尽管每次Pbind
都清楚地发送。\something
也没有其他值可以工作:0
等nil
。
然而,平等测试myParam == myParam
并且\something == \something
确实有效,所以在这些情况下,我得到一个单调的旋律。
我只能猜测 aPbind
在某种包装器中发送每个值,但我不知道如何从合成器内部检查它们。任何人都可以帮忙吗?
