Read the content of a buffer at an index.
In comparison to PlayBuf : PlayBuf plays through the buffer by itself, BufRd only moves its read point by the phase input and therefore has no pitch input. BufRd has variable interpolation.
| numChannels |
Number of channels that the buffer will be. This must be a fixed integer. The architecture 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 BufRd, it will post a warning and output the channels it can. |
| bufnum |
The index of the buffer to use. |
| phase |
Audio rate modulateable index into the buffer. WARNING: The phase argument only offers precision for addressing 2**24 samples (about 6.3 minutes at 44100Hz). |
| loop |
1 means true, 0 means false. This is modulateable. |
| interpolation |
1 means no interpolation, 2 is linear, 4 is cubic interpolation. |
