Eddie, glad open works for you. Other tips you may be unaware of since you don't use BIAB much and if you only are interested opening BIAB MIDI project for the Chords is to Open the MIDI file and change the Style that loads to a BIAB Blank Style (search StylePicker for Blank - there's 4-5 blank styles) and ERASE the imported MIDI file residing on the Melody Track and save the BIAB project as an SGU file rather than MGX. Doing this will open RB with Chords but no MIDI tracks you'll have to delete. Selecting one of BIAB's Metronome styles will load RB with chords and a click track set to the tempo of the BIAB file.

Since you also play keys, anything you may be working on using your keyboard, can be saved as a MIDI file and opened in BIAB loading the Chords, tempo, key signature, feel and a default Midi Style. Just saying homemade works equally well as professional store bought for how you're using MIDI.

What you're doing is a great way to quickly get from idea to BIAB project, including melodies.
