Hello
I have retired from my previous life and now taking the time to return to the piano and percussion instruments I grew up playing. Many years of piano, drums, orchestra percussion, all analog. I am now learning Pro Tools 10, Kurzweil SP4-8, Korg Wavedrum and this time, all digital. Grew up playing classical and pop (60's). Organum is a term used in the early centuries of polyphony. Thanks for the SP4 sounds by the way.
