Cycling '74 RNBO RNBO Sampling Variable-rate looping sample playback of a sized buffer

The groove~ object is a variable-rate, looping, sample-playback object which references the audio information stored in a buffer~ object having the same name.

Buffer to use

Names the buffer~ object containing the sample to be used by groove~ for playback.

Number of channels to read.

A second argument may specify the number of output channels. The default number of channels is 1. If the buffer~ being played has fewer channels than the number of groove~ output channels, the extra channels output a zero signal. If the buffer~ has more channels and is a multiple of 2 or 4, channels are mixed.

Loop min (ms).

Sets the sample playback start position in milliseconds.

If multiple buffer names are declared to be used, this sets the currently active buffer using an index [0 based]. Enable an attempted crossfade on loop jumpback. The fade depends on available sample material (ms). Loop max (ms).

Sets the sample playback end position in milliseconds.

The word loop, followed by a `0` or `1`, disables/enables looping. Playback rate.

Defines the sample increment for playback of a sound from a buffer~ . A sample increment of 0 stops playback. A sample increment of 1 plays the sample at normal speed. A sample increment of -1 plays the sample backwards at normal speed. A sample increment of 2 plays the sample at twice the normal speed. A sample increment of 0.5 plays the sample at half the normal speed. The sample increment can change over time for vibrato or other types of speed effects. The groove~ object uses the buffer~ sampling rate to determine playback speed.

Stops the playback of the buffer. Playback rate.

Loop min (ms).

Sets the sample playback start position in milliseconds.

Loop max (ms).

Sets the sample playback end position in milliseconds.

The sample output. Sync output (phase, samples, ms)

Outputs the current playback location samples, phase (0..1), or milliseconds depending on the syncmode attribute. Location is relative to the synctype attribute, which either scales the sync output to the current loop range or keeps it in the range of the buffer's length.
