P-H .... I'm definitely not an expert in this and do not have my kn6 here to try it first, but I think you should be able to do this using 'Step Record' ... There probably is an easier way, and perhaps one of the 'techies' will respond ....
That is a great Louie Prima tune, and I actually got a midi off the net that I did some 'tweaking' to and it sounds pretty much like his recording....
