Hi ErichS.. Ive solved my problem transfering patterns, I have a rack of cd's containing a wealth of midi sounds from actual songs to drum sounds, I saved them onto a usb pen, plugged it into my roland sonic cell, went midi out from sonic cell to midi in on alesis, played drum sound on s/c and recorded on alesis and you just play/record the first bar and thats it, when you play it back on alesis it keeps repeating that section so for now thats a big step in the right direction, I can now work with that pattern now its on board... you were right re drum mapping when I tried it on my yamaha it just sounded awful but through s/c it was perfect...
regards
kim
