Error, i finally found 3 styles in BIAB 2014 Megapack that have a 5/4 signature. You have to open the Style picker, without filtering anything, and there is a chapter near the end of the list for odd number time signatures.

However, the styles that i found do not fit very well with the Dave Brubeck tunes. Unless these styles exist in upper BIAB versions like the Everything Pack, it would be nice do develop appropriate styles , in Midi or (better) in real style.

BIAB does not recognize 5/4 natively. With the edit menu you can ask for 5/4 but BIAB considers that it is 3/4+2/4 . It would be nice to have a true 5/4 in BIAB 2016 ! Thank you!
