My wish list for Master Tracks Pro is not that big now, because I was always very satisfied with the program.

The last version 6.8.4 ran without resource problems on 32bit platforms and supported LSB/MSB, but had problems with the correct instrument assignments.
At least it happened that I had “Piano” on all tracks after opening a MIDI file.
In the track editor, the correct instruments were displayed, but these were only applied to the track when I clicked on them with the mouse.
That means with 8 instrument tracks 8 times click!
So let MTP from the operation as it simply as before.
Also the red marker arrow (text and Add MCI Event) was used by me regularly.
Nice would also be the function “right mouse button”.
