Thx, stratos, for the advise,

but, trust me, Natural arrangement has nothing to do with it.

You can leave it on or switch it off, per instrument, in global settings.

The thing is, Biab only knows 7 chords.

A typical chord progression to test is
CmMaj7 (it will play b7)
C7b9 (it will play natural 9!)
C7#9 (it switches between dorian: 12b3456b7 and mixolydian, a natural 9)

A typical style to test it is: dizzy jazz or bebop

Biab is very limited and it’s hard to see this after more than 20 years of updates.


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