K5synth

Hello folks,

I just got a secondhand K5, no manual, and i'm loving playing with it,
but i wondered how do i get the synth to be truly multi-timbral? in that
it can play more than one sound at once using a midi sequencer, how do i
assign a different midi channel to each sound that i choose so that it
doesn't play just one sound all the time.

Thanks in advance.

Rob.
