Hi

This is a bit complicated to explain but here is my take.
Your midi keyboard sends its data to the software over Ch1

The through track is just that, it passé your note and midi data that you play through to the internal pc midi synth say Microsoft GS Wavetable, or any other external hardware midi synth or sound module that you select in midi settings, it sends this to ch5 of the receiving synth, you may chose the patch for this in the through track.
This is what you hear when playing or recording.

If you chose to record to the melody track the note and midi data that you play gets written here on the melody track what you are hearing is the through voice chosen previously from the chosen internal or external synth.

Now when you play back you song your notes and data are coming from the melody track the melody track sends its data on ch4 using the patch selected for the melody patch. The data is sent depending on you midi set to either your dxi synth if the box is ticked or to your internal or external midi synth or module as selected.


Later edit
Note the thru track does not have to routed to the midi internal or external synth drivers just don’t tick the box in midi set up
It will then go to your VST dxi if selected the ch assignment are still as stated

Hope this helps a bit
Best regards
Mike
