Question

Whenever I create a new track, in all of my sessions, I am confident that creating a new track used to make an insturment track with no instruments ("None"). Now, when I create a new instrument track it, by default, chooses the Multi Instrument option.

Answer 1

You can just drag your instrument into the arrangement and it should load just the instrument instead of multi-instrument.

Otherwise, you can create an empty instrument track (make sure to check "None" under the "New Instrument" output) and then drag your instrument over that track.
