@title{(buf-rd numChannels rate bufnum phase loop interpolation)}
|
||
|
|
|
||
|
|
Plays the content of a buffer.
|
||
|
|
|
||
|
|
The number of channels must be a fixed integer. The architechture
|
||
|
|
of the SynthDef cannot change after it is compiled. NOTE: if you
|
||
|
|
supply a bufnum of a buffer that has a different numChannels then
|
||
|
|
you have specified to the buf-rd, it will fail silently.
|
||
|
|
|
||
|
|
The interpolation type is an integer: 1 no interpolation, 2 linear
|
||
|
|
interpolation, 4 cubic interpolation.
