Experiencing some strange audio issues with my current project, curious if CC 121 will reset both pan and volume on all devices.

My files, having been run through various different editors, and having their contents re-arranged (looking at you, Anvil Studio and Cakewalk!), all seem to show a similar flow of events at the start of each track.

The bank selects and program change used to be together.  Some other events were in other spots.  I used Cakewalk to insert a measure at the beginning of each song.

I now see that volume and pan are being set at tick 1:1:0, yet the CC commands for All Notes Off, Poly On, and Reset All Controllers are happening afterwards at 2:1:0, presumably in their original locations before the measure was inserted.

Is this sequence of events resetting my pan and volume back to defaults after they've already been set?
