Solo then unsolo midi tracks should un-solo instrument track

[Josh Wolfer]

I have a particular use case and I'll do my best to explain it. I'm working on synthestration and my track structure looks as such:

• a Track folder with a bunch of instrument tracks in it
• Track folders labeled with a "version" of the score I'm working on.
  • within these version folders are MIDI tracks that correspond to the available instrument tracks in the "instruments" folder.

I make big changes to the score periodically and I essentially just duplicate the "version folder" which contains the midi tracks and continue from there. Yes, I could keep these version iterations in their own project files, but I like to have quick access to the previous versions. Loading in a ton of sample libraries in/out just to hear previous version, is not ideal. Also, I like being able to compare notes and harmonic structures, all in the same project. And midi data is small. This shouldn't be a big deal at all. 

The Challenge

I'm constantly soloing out different groups of midi tracks in order to hear how they're playing with each other. When I solo a midi track(s),  it works exactly as you'd expect. But when I unsolo the midi tracks, I get no sound, because the source Instrument track remains solo'd, but there are no corresponding midi tracks to feed the instrument track. 

I have to go to the console bar and click the solo button to un-solo everything and now I'm back to normal. 

This is unideal. 

What I'd like is that if you solo a midi track or group of midi tracks that feed an instrument track, upon un-soloing the last midi track that feeds the instrument track, both the last midi track AND the instrument are no longer solo'd. 

This would have a much more pleasant work flow.
