Hello Frankii,

1. You can use an external MIDI keyboard to enter chords, by playing the chord and then pressing Command+Enter

2. There is a "Re-harmonist" feature that can make a chord progression for you based on a melody that you input, however this was added in Band-in-a-Box 2009, so you would need to upgrade your version.

3. No, RealTracks can only be used in Band-in-a-Box 2009 and higher. The chart on this page shows upgrade options ("from 12 or earlier")...
