I had one of the first K-1's and also one of the first K-1 II's. The trouble with them is that they worked using the Multi config. system. By this I mean that you went in and set up a Multi Patch which consisted of the insturments that you wanted to use on a given song. You can change those patches within the Multi Patch but if I remember right you only had from 1 to 64 that you could select unless you had a memory card, Then you had more. What I have done when using one in the studio (I have a friend who still has both) is set up a patch map in which I can work with. You should be able to set up a user patch map in both programs and should have no problem after that. If you have a problem let me know and I will go into Cakewalk (which I hate to use) and configure one for you and send it to you.
Good Luck
