Class Methods

.ar

Arguments:

trigger	A kr or ar trigger to start a new grain. If ar, grains after the start of the synth are sample accurate. The following args are polled at grain creation time.
dur	Size of the grain.
sndbuf	The buffer holding an audio signal.
rate	The playback rate of the sampled sound.
pos	The playback position for the grain to start with (0 is beginning, 1 is end of file).
envbuf1	A buffer with a stored signal to be used for the envelope of the grain.
envbuf2	A buffer with a stored signal to be used for the envelope of the grain.
ifac	An interpolation factor. interpolates between the two envelopes where 0 is all envbuf1, and 1 is all envbuf2.
interp	The kind of interpolation for the sampled sound in the grain (1 - none, 2 - linear, 4 - cubic).
