From Montreal Assembly:
The 856 for ZELLERSASN (856) is a looper which allows playback of many layered copies of a single recording, each layer can have various unique manipulations of the original recording. Portions from the recorded loop can be played back in various rhythms and at different pitches. Once a series of transformations has been composed, this sequence of manipulations can be stored and can be applied to new loops/recordings.
