seems to produce redundant, empty tracks

Using code like

local s =
local ntracks = s:getTrackCount()
print("ntracks", ntracks)

I get an output of 2 where I expected 1 based on the midi file; Garagaband also sees 1 track.
The extra tracks seems empty.

When using the "arrange" tab of the excellent online midi editor

We can see that the empty tracks are actually in the midi. It's named "conductor track". In another file, 4 extra tracks where even included which seemed to be misused for copyright info, in the sense that they were empty tracks with names like "song X by artist Y" and "copyright 2020" etc.

Apparently it is customary to hide empty tracks; which makes this practice of added copyright info there pretty useless and confusing
