PatternConductor

Simple interactive control for playing patterns
Inherits from: Object

Description

PatternConductor provides a simple interactive control (supporting play, pause, resume, stop) for playing pattern, much like Pattern: -play. However, PatternConductor creates its own clock and directly controls the release of sounding notes as well as their initiation by the pattern.

*new (patterns, event, quant)

Instance Methods

-tempo

-tempo = temp

Sets the tempo of the PatternConductor

-play

Play the pattern. A TempoClock is created, its tempo is set to the PatternConductor tempo, and the pattern is played using that clock. If quant is non-zero, this is synchronized with TempoClock.default at the specified quantization.

-pause (pauseTempo)

Pause the pattern, sustaining notes indefinitely. A subsequent -resume will return to the original tempo (so the notes will end as scheduled). A subsequent -play will cut-off any sounding notes and resume play at the original tempo.

-stop (stopTempo)

can cut-off or shorten sounding notes, depending on the value of tempo. If stopTempo is nil, all notes are cut-off immediately. Otherwise, notes end at the specified tempo.

Examples

(
// a pattern with long notes
p = Pbind(
    \freq, Pwhite(0,log(32)).exp.round(1) * 36.midicps,
    \detune, Pfunc({ | ev | ev[\freq]  * rand(0.01) }),
    \sustain, Pwhite(log(0.1), log(20)).exp,
    \dur, Prand([0.1,0.1,0.1,0.1,0.2,1,2],inf),
    \db, Pstep(Pseq([-20,-30,-25,-30], inf),0.2)
);

// unrelated cluster pattern running on TempoClock.default
Pbind(\dur,2, \midinote, Pseq([(48..60)],20), \db, -30).play;

// make a conductor
a = PatternConductor(p, quant: 2);
a.play;
)


// now try some interactive control options line by line:
a.quant = 0;
a.pause;
a.resume;
a.stop;
a.play;
a.pause;
a.play;
a.stop(1000);
