Hi Mac. Well I tried that - and it would be great except that there is quite a delay betwwen htting the key and getting the note. I guess thats what you call latency? The delay is probably only a fraction of a second, but this makes it very difficlt to use, even if its only a simple rhythym.

BTW I'm using the latest brand of coal and have a full head of steam (Win 7 4GB RAM etc)
