How to set up an instrument on a separate MIDI channel?

For example, I want to play Kick, Snare, and HiHat on the Tracker simultaneously.

This is not possible. You can only play one sample/instrument at a time on the Tracker via MIDI. Now if your instrument is a beat slice, this could still work though.

This is called MIDI Synthesizer Mode by the way.
You can read more about it in the Manual - Section 11.9 MIDI Synthesizer.

There is a wish regarding allowing changing instruments via MIDI for this mode:

Change Instrument via MIDI in Synth Mode

Allow changing of instruments in MIDI Synth Mode. What is the problem? The Polyend Tracker can only use a single instrument at a time when in Synth-Mode. Instruments have to be changed by Hand on the Tracker. What do you want to achieve? Send a midi message (probably Program Change), to switch Instrument via MIDI. Are there any workarounds? Switching instruments by hand. Any links to related discussions? Any references to other products? Akai S1000 maybe? In fact any hardware sampler.
