I use BinaB, an older version. Some years ago, I took tunes from Dick Hyman’s ‘Chord Substitutions and Changes for 100 Songs Every Musician Should Know’, plugged the changes into BinaB, edited each tune down to drums, bass and jazz guitar (using the BinaB rhythms), and converted them into midi files. They have been my ‘cocktail hour’ staples for years now. I use PowerTracks to edit all midi files …
Ciao,

PS; I also did many of Hyman's second '100 tunes ...'the same way.
