First of all, MIDI channels and DAW tracks are two different things. Channel 3 can be on track 7, for example. They do not match up (although you can make them match up if you wish, but they don't have to).

The track is nothing more than where music content is recorded and stored for playback. A MIDI track can actually have multiple channels in the content (each note has a channel associated with it), and you can also have the same channel play on multiple tracks (however, this can sometimes introduce some unintended sounds).

The general MIDI specification allows for 16 channels to work with. Channel 10 is generally reserved for drums. Assuming that the MIDI data on your track is only using one channel (and PTPA has a feature to rechannel the MIDI data to whatever specific channel you want), your MIDI track will send that data (the notes) to the MIDI synth using the channel defined for those notes (for example, the melody channel from a BIAB file is channel 4). The receiving synth (for example, Kontakt) must be set to listen for data on the specific MIDI channel. It will play back whatever arrives on that channel and ignore data from any other channels.

Some synths (such as the Coyote Forte or the Cakewalk TTS-1) are set up to automatically route each received channel to one of 16 output channels, so you don't have to expressly set the channel like you do with synths like Kontakt.

Don't know if that helps any.
