AllBuf | SuperCollider 3.13.0 Help

Description

AllBuf is a convenience class which produces all manners of SynthDefs for playing back buffers.

It makes sort of smart decisions about how to create patches based on your input parameters and it contains a method for factory producing all variations of SynthDefs for arbitrary input (number of channels in the buffer) and output channels.

It automatically creates variations of the SynthDefs containing pitch envelopes, low pass filter and filter envelopes which can all be easily used in patterns etc.

The idea is to create all possible SynthDefs using this class in one line of code: // Create Buffer Player synths in variations for mono and stereo buffers, outputting to stereo a = AllBuf.new(maxinchans: 2, outchans: 2); ~bufpath = Platform.resourceDir +/+ "sounds" +/+ "a11wlk01.wav"; b = Buffer.read(s, ~bufpath); // Get synthdef name for mono buffer player, with filter and pitc h envelopes ~synthname = a.def(inchans: 1, filterenv: true, pitchenv: true); // Play synth ~synth = Synth(~synthname, [\buffer, b, \rate, 0.95, \dur, 8])

Class Methods

.new

Create an instance of AllBuf

Arguments:

maxinchans

Maximum number of buffer channels.

This will create variations of synths with number of buffer channels up to and including this number

outchans

Number of output channels

verbose

Boolean. To post or not the info of the synth creation process.

Returns:

An AllBuf

Instance Methods

.def

Get the synthdef name for a certain synth

returns: Symbol

Arguments:

inchans	Number of buffer channels
filterenv	Add filter envelope to synth
pitchenv	Add pitch envelope to synth

Examples

// Create Buffer Player synths in variations for mono and stereo buffers, outputting to stereo
a = AllBuf.new(maxinchans: 2, outchans: 2);

// Load a sound
b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav"); // remember to free the buffer later.

// See number of channels in buffer
b.numChannels;

// Play pattern with a bunch of random parameters 
(
 Pbind(
     \instrument, a.def(inchans: 1, filterenv: true, pitchenv: true),

     ).play

// Used with PolyBuf
// Install:
Quarks.install("PolyBuf")

// Sequence all samples in b in a random order, playing them in full length
b = BufFiles.new(s, "frokostsamples");
