@LtKojak, haha.
Your link to Tracktion Waveform? It gives you a chord progression in one key. But most of us are way more sophisticated than that, :))) you should check our deft sense of harmony. I'd go all tritone on this app!

As for jazz styles, they seem to have more than one! But no more than ten. Pgmusic would rip this app to shreds.

Imagine: you're practicing a song (as you should, because Mark Levine told you so!) in all twelve keys and that one pattern keeps repeating itself in all keys. You'd go medieval on it anytime soon.

Sadly, this happens in biab too: playing in twelve keys and hearing the same bass line over and over again makes you sad, lonely, resentful and overeating, possibly even turning to illegal substance use.

Biab, Kontakt, Sampletank and lots of nice libraries, from Fluffy audio to Abbey Road drums.
