Hey Manbot,
The CS1X has 16 part multitimbre which usually means you can set a channel to each timbre, but the manual is a bit bigger than one page, so I didn't go through it too finely and as a result can't tell you how to set it up to do so.
Perhaps reading it yourself may help you setup your CS1X to receive and play multiple midi channels on separate instrument patches.
I've read manuals for other people recently, I know, but this one is like 64 pages long and isn't presenting me with the info we need in the contents.
God luck
