After not having used Biab for a long time, I started using it on and off again since version 2012 and buying all the updates. I have 2018 now. Midi with good Kontakt instruments sounds killer. (It does)

Biab knows a lot of chords, but doesn’t play them correctly. It’s been like this since I started using it in the nineties. Realizing this hasn’t changed despite all the features and updates, makes me sad.
After checking over and over again, I came to this conclusion
(Turned off and on and off again natural arrangement and a lot of other features. But these settings do not really affect the results)


Biab does know
Difference between maj7, dom, minor7
Cm#5
C13+

Biab doesn’t know
CMaj7#5, instead it plays C7#5!
CmMAJ7, plays m7 (what about Chelsea Bridge, Nightlake...)
C7SUSb9, plays natural 9th: useful for all things ECM and Marsalis Hardbop
C7#9, thé Blues chord, Goodbye Pork Pie Hat, Beauty & the Beast (Wayne Shorter)
C7#9b13, an alternative to the C7b9, much more dissonance, cool
C7b9, Every standard without much exception. Your tone deaf neighbour plays natural 9
C7#11b13 biab plays 4 and natural 6
C13b9, the Caravan chord, and a staple chord for going to major chord a fourth up.
C7b9b13 thé altered chord every bopper uses.

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