Cheers Drakelife…
I’m starting to work through midi files which I have used to produce WAV. files as backing tracks for my duo. One advantage is that I know the songs parts are in the right order 
I got fed up with being tied into rigid backing tracks and wanted a more dynamic and simpler sound.
Apart from the BeatBuddy, I have also started using the Electro-Harmonics C9 Organ Machine which works well with some songs and fills the sound out.
