PlayBuf

A UGen to play back samples from a buffer in memory.

PlayBuf provides a kind of high-level interface to sample-playback, whereas BufRd represents a kind of lower-level access. While BufRd has a random-access-pointer in the form of a phase input, PlayBuf advances the phase automatically based on a given playback speed. PlayBuf uses cubic interpolation.

numChannels: the number of channels that the buffer will be. Since this is a constant, a change in number of channels of the underlying bus must be reflected by creating different SynthDefs. If a buffer identifier is used of a buffer that has a different numChannels then specified in the PlayBuf, it will fail silently.
buf: the identifier of the buffer to use
speed: 1 advances the play head by the server's sample rate each second. So 2 means doubling speed (and pitch), and 0.5 means half speed (and half pitch). Negative numbers can be used for backwards playback. If the underlying buffer represents a sound at a different sample rate, the rate should be multiplied by BufRateScale.kr(bufID) to obtain the correct speed.
trig: a trigger which causes a jump to the given offset . A trigger occurs when a signal changes from non-positive to positive (e.g. <= 0 to > 0).
offset: sample frame to start playback. This is read when a trigger occurs. It may be fractional.
loop: 1 to loop after the play head reaches the buffer end, 0 to not loop. This can be modulated.
doneAction: what to do when the play head reaches the buffer end. This is only effective when loop is zero.
