07-multichannel-expansion-2.py - Extended multichannel expansion.
============================================================================================================================================


When using multichannel expansion with lists of different lengths,
the longer list is used to set the number of streams and smaller
lists will be wrap-around to fill the holes.

This feature is very useful to create complex sonorities.
