polygon-rhythm

Recommended Posts

The forthcoming POLYGON-RHYTHM function will allow you to think and compose in a clear symmetrical structures. The great amount of keywords (OPMO stile) makes this algorithm very powerful.

 

This is a short example using POLYGON-RHYTHM exclusively.

Instruments: VSL Tenor Sax and Jazz Drumset.
