Record-enable should toggle track MIDI Input
I thought this was a bug, but after interactions in the bug-report forums, I think this is just something that was passed-over.
In most DAW's I've used, the record enable button enables and disables the track's MIDI Input when toggled. In other words, MIDI Input is off when the record arm/enable button is off, and on when it is on.
This will allow users to use external synthesizers/gear with BM3 and use only a single external MIDI controller to control them all, all the while looping/recording in BM3.
I think this would be a super simple feature to put in. (ex: when track's record-enable is on, MIDI Input is allowed. When it is off, MIDI Input is off). And it can also be an optional setting.
