A UGen which reads the content of a buffer, using an index pointer.
Warning: if the supplied buf refers to a buffer whose number of channels
differs from numChannels , the UGen will fail silently.
An alternative to BufRd is PlayBuf . While PlayBuf plays through the
buffer by itself, BufRd only moves its read point by the index input and
therefore has no pitch input. PlayBuf uses cubic interpolation, while BufRd
has variable interpolation. PlayBuf can determine the end of the buffer and
issue a done-action.
- Value Params
- buf
the identifier of the buffer to use
- index
audio rate frame-index into the buffer. Can be fractional.
- interp
1 for no interpolation, 2 for linear, and 4 for cubic interpolation. ''(init-time only)''
- loop
1 to enable looping, 0 to disable looping. this can be modulated.
- numChannels
number of channels that the buffer will be. Since this is an integer constant, a change in the number of channels must be reflected by creating different SynthDefs.
