*loop is an 8-voice sampler which plays back pre-recorded audio material and creates loops of different structure. The speed of the loop can be set either independently or it refers to the pitch of the corresponding note.
The loop can be selected manually or in random position with a fixed loop length. The loop length can also be synchronized to Ableton Live's tempo settings.
Scrubbing through the sound file is possible without clicks and glitches, as each selected loop is played as a new voice, while the previous loop is allowed to decay in the desired time.
The successive loop courses can be crossfaded to smoothen start and end points. Hereby each loop consists of two parts which run in the same or in different directions, which can be detuned individually and which fade times can be varied.
Furthermore, an envelope can shape the individual voices or the polyphonic overall sound.
Further documentation can be found in the Max for Live device if Ableton Live ́s Help View is turned on.
