Hi Matt,
I'm a jazz player, but I use BIAB to merely accompany myself as I practice a new melody/song. I don't use it on the job.
I use almost exclusively, ''Bogey - Slow Swing Ballad''. as the style closest to what I hear on the bandstand. I have used other styles, but Bogey is my choice. MIDI is not used.
The melody in question, is fairly simple - 32 bars in Eb - (ie) 2x16. Because the melody is so simple in structure, any variation from what I programme, stands out immediately.
I'm used to a banjo supplying the chords in the 6 piece outfit I play with. The banjo player will play passing chords occasionally, but will not change to anything other than what is in our book.
PS...I'm new to BIAB 2016, but have used a fairly basic 1998 version, up until about two weeks ago. I didn't have this problem with 1998...but it's much simpler. The supplied manual does not seem to answer my query in a way that is clear to me.
Thanks again...
