MM - General work with Granulators.

MM – General work with Granulators.

It covers:

– PlayBuf with stereo samples.
– GrainBuf with stereo samples.

SynthDefs include lots of options.

MIDI Input:
Includes complete MIDI implementation.
Keyboard noteOn and noteOff
cc1 (that you can copy and assign to other cc’s)
Pedal
Pitch Bend.

Implementation takes into account last cc value for subsequent notes. Overall a pretty clean routine.

Pbind examples. From simple to complex Stochastic clouds.
Examples on how to use FreeVerb.
Examples of multichannel expansions.

You’ll need this sample:
You can drag this sample into SCs code directly, no need to type them in.
