Hello Markus
Here is a link to a post about playing on the fly. http://www.synthzone.com/ubbs/Forum37/HTML/013675.html
Another tip which I have heard from virtually all professional players, is that if you play in a band or group, forget any type of sequences including SMF as they do not work, you must always learn to play live.
Hope this helps

Bill
