AlgaMonoPattern | SuperCollider 3.13.0 Help

Description

An AlgaMonoPattern is a monophonic sequencer with interpolation capabilities. It works similarly to an link AlgaPattern, with the difference of the pattern being triggered sequentially. AlgaMonoPatterns feature a set of special keys:

1. rate - The rate of the sequencer, defaulting to \control. Accepted values are: \control, \kr, \audio, \ar.

2. chans - The number of channels of the sequencer, defaulting to 1. This can be aliased to channels, numChans, numChannels.

3. in - The values of the sequencer. This can be aliased to value, val.

4. time - The interpolation times between triggers. This can be aliased to interpTime, it.

5. shape - The interpolation shapes of the interpolation times. This can be aliased to interpShape, is.

Examples

//Simple example
(
Alga.boot({
    //Our mono sequencer
    ~seq = AlgaMonoPattern((
        in: Pseq([220, 440, 880], inf),
        time: Pseq([0.05, 0.1, 0.5], inf),
        dur: 0.5
    ));

//The AlgaNode to modulate
    ~sine = AlgaNode({ SinOsc.ar(\freq.kr(440)) }, [\freq, ~seq]).play(2);
});
)

//Audio rate manipulation
(
Alga.boot({
    //Mono sequencer featuring AlgaTemps modulating at audio rate
    ~freqSeq = AlgaMonoPattern((
        rate: \audio,
        chans: 2,
        in: Pseq([
            AlgaTemp({ SinOsc.ar([Rand(1, 100), Rand(1, 100)]) }, scale: [Pwhite(220, 440), Pwhite(440, 880)]),
            [440, 660],
            880
        ], inf),
        time: Pwhite(0.01, 1),
        dur: Prand([0.125, 0.25, 0.5, 1], inf)
    ));

//Mono sequencer featuring AlgaTemps modulating at audio rate
    ~ampSeq = AlgaMonoPattern((
        rate: \audio,
        in: AlgaTemp({ SinOsc.ar(Rand(1, 1000)) }),
        time: Pwhite(0.01, 1),
        dur: Prand([0.5, 1, 2], inf)
    ));

//The AlgaNode to modulate using both FM and AM
    ~sine = AlgaNode({ SinOsc.ar(\freq.ar(440!2)) }, [\freq, ~freqSeq, \amp, ~ampSeq]).play;
});
)
