Video demo of Polythemus AU midi app Out Now!!
This app was designed to turn mono synths (including hardware ones) into polyphonic ones, but then the voice allocation can also be 'played'.
Here is my first video demonstrating a multi-timbral iVCS3.
Currently only AUM supports multiple output channels from midi effects, but both apeMatrix & Audiobus have this in development.
The app will be available shortly (when Apple understand that AU has to have a host!).
