Poly Editor and Multi-Seq Specific Features

Poly : Polytemporality and Polymeter

Within a poly, each voice can have its own time signatures, channel and tempo, so as to build polytemporal and metric structures. The score is then organized according to absolute durations.

Multi-Seqs : Internal Chord-Seq Edition

Within a multi-seq, chord-seqs must be open in internal windows to be edited separately.
