Hi list
I do not know if this is appropriate or even interesting, but to me it
was, so I guess someone else will be happy for this as well.
There is a java program at
http://www.cs.hmc.edu/~keller/jazz/improvisor/ which works great on
linux. It even has the possibility to use band in a box files. It is
made t function as a playalong program for jazz improvisation, but it
also generates improvisations and is excellent in my opinion to sketch
on new song ideas in jazz styles.
Probably closed source though.
Best regards
Ketil
