I'm not sure I've understood anything at all. You can have only one
instrument at a time on any channel. The preset change control will
change the instrument that sounds on the given channel.

Playing several instruments (on several channels) at the same time might
be acomplished using seq24. This great midi sequencer uses buses to
route midi events thru jack. I use it as a simple midi router. Other
midi sequencers might be capable too, but I haven't tried any.

QSynth/Fluidsynth creates several ports, each one has 16 midi channels.

Best regards.
