I posted the following on the Mac forum with no luck do far and as this gets lots more participants I'll try here:

Im after advice on a suitable track so I can rehearse the Bari solo in the BB chart Superheroes (On a Recue Mission) by John Kristenson.

Its a time signature of Minim (half note) = 92 so has a two feel and described as 2nd Line or Back Line. It is whacky chart and has a funky feel.

Ive tried some funky stuff in half time but the Marinethal solo sounds very forced. The voice leading is so poor. The changes are EbMaj7, Dmi7/G, G7b13b9, EbMaj7, Eb1/2dim/F, Ami7/D, D7b13b9.

Can anyone suggest a suitable track, Ive tried disabling Natural Arrangement but to no avail. I have the 2017 version of BIAB.

Thanks, Malcolm
