PingPong | SuperCollider 3.13.0 Help

Description

Bounces sound between two outputs… Like a ping-pong ball. PingPong is actually a compound built upon RecordBuf and PlayBuf .

Class Methods

PingPong.ar(bufnum: 0, inputs, delayTime, feedback: 0.7, rotate: 1)

Arguments:

bufnum	First index of a multi channel buffer.
inputs	An array of audio inputs, the same size as your buffer.
delayTime	Delay time in seconds.
feedback	Feedback coefficient.
rotate	Which rotates the inputArray by one step. (left → right, right → left). Rotation of 0 (or 2) would result in no rotation to the inputArray. You cannot modulate this number by assigning it to a control in a SynthDef.

Examples

(
s = Server.local;
s.waitForBoot({

b = Buffer.alloc(s, 44100 * 2, 2);

SynthDef("help-PingPong", { |out = 0, bufnum = 0, feedback = 0.5, delayTime = 0.2|
    var left, right;
    left = Decay2.ar(Impulse.ar(0.7, 0.25), 0.01, 0.25,
        SinOsc.ar(SinOsc.kr(3.7,0,200,500)));
    right = Decay2.ar(Impulse.ar(0.5, 0.25), 0.01, 0.25,
        Resonz.ar(PinkNoise.ar(4), SinOsc.kr(2.7,0,1000,2500), 0.2));

Out.ar(out ,
        PingPong.ar(bufnum, [left,right], delayTime, feedback, 1)
    )
}).play(s, [\out, 0, \bufnum, b.bufnum, \feedback, 0.5, \delayTime,0.1]);

})

        Resonz.ar(PinkNoise.ar(4), SinOsc.kr(2.7,0,1000,2500),
0.2));

Out.ar(out,
        PingPong.ar(bufnum, [left, right] *  EnvGen.kr(Env([1, 1, 0], [2, 0.1])),
            0.1, 0.8, 1)
    )
}).play(s, [\out, 0, \bufnum, b.bufnum]);
