MIDI channel, Multi-timbrals, Tracks, and Parts

MIDI uses 16 Channels on which to transmit/receive information. There are also discrete pathways just like a track and a mixer Channel, but a MIDI Channel and a Mixer Channel are not the same. Track 1 always goes with Mixer Channel 1. You can assign the data being recorded, or the data being played back on Track 1 to come in/go out MIDI Channel 1, but it could use any MIDI Channel. For instance, if you are do not know how to play piano that well,  you might record the RH part on Track 1, and the LH part on Track 2. Still you could assign both of them to MIDI Channel 7, if you would like, and of course your MIDI instrument would be set to play a piano sound on Channel 7.
Devices that can receive information from multiple Channels are called Multi-Timbral and can play up to 16 sounds, stored in 16 locations called "Parts" that are in a 1:1 relationship. Therefore, in a MIDI Sequencer, MIDI Instrument, each Part has a MIDI Channel that stays with it, however any sound may be put on any Part.
