The way BIAB cuts up, transposes and reassembles portions of bass phrases from the original source audio recording contained in RealTracks might be fine for other styles - ie those that predominantly use bass *riffs* - but for walking bass lines - even though BB uses REAL recordings of pro jazz bass players doing their thing over the changes this gets reprocessed in a way that at so many times is simply inauthentic. It's actually one major reason I still often prefer to just use actual commercial jazz backing tracks from the likes of Jamey Aebersold.

Why? well a lot of it has to do with jumps in the baseline that no longer "lead" from one closest note to another. It actually makes it extremely easy to spot when a jazz backing track on YouTube for example is coming from real pro recorded jazz musicians or from our fave practice tool - BIAB.

I think the answer can be done algorithmically- and doesnt require any AI - but in any case this has been going on for ages. Decades actually. It applies as well to MIDI jazz walking bass lines.

Maybe PG should reach out to their past jazz bass realtracks musicians - hey! - even Ron Himself - and ask them where they can point out why they would never have done what there RT algorithm is doing to their own notes and phrases.
