I bought a Kronos precisely because I wanted to stop carrying around too much boards. Previously I worked with a Nord Stage, Fantom S and Moog Voyager. Nice setup, but it was just too much.
I play with many sounds in one song. For instance I use hammonds, piano's strings, bells, Taurus bass (programmed in AL1), mellotron samples and one or two lead sounds in every song.
Fortunately, the Kronos is able to do all these things within one combi. For instance, I use the expression pedal to morph between the piano's and hammonds (using two limiters, with mirrored settings), with Karma I can select four different modules each with different soundsets. And of course I use a lot of layering and splits.
I do have a Roland PK5 pedal set to play the Taurus bass and the nanopad for triggering samples.
So it's all possible with only the Kronos. But nevertheless, I was wondering if I could use my EMU longboard (I use that one on the camping

) assigned specifically to one chanell, for example strings. But I am not sure if I can do that, since I have only one midi in, and that one is used already by the PK5.
