Description

Class Methods

*ar (trigger: 0, dur: 1, freq: 440, envbuf, mul: 1, add: 0)

Arguments:

trigger

A kr or ar trigger to start a new grain. If ar, grains after the start of the synth are sample accurate.

dur

Size of the grain. Polled at creation time.

freq

The freq of the grain generators internal oscillator. Polled at creation time.

envbuf

A buffer with a stored signal to be used for the envelope of the grain.

mul
add
