IMHO modes are for the solo instrument.
Chord tones are for the accompaniment instrument.
As most of us play chord tones when accompanying and only go to modes when we get a lead break......
Are you getting lead breaks? If so work on modes, if not, wait until you do.
Of course IMHO.
Geez, I don't know about that. My band has a tune with a section that is simply Dmin BbMaj7.
Over the BbMaj7, I play an e-natural in my line; because the tune is in D natural min (relative minor to FMajor) and the BbMaj7 chord thus functions as the vi chord of Dmin (IV chord of FMajor). That's a practical application of modality. Of course, the general rule of "no natural 4th with a natural 3rd" applies too.
