Sorry but i have to say this:
In 100 Young user of Arranger i barelu see one 45-65 old arranger user, West or my community.
Next, Bachus, the FillIns for OL KARMA already exist and they might be implemented in M3.
The M3 KARMA was somewhere on an official page it wasnt only a rumor but i forgot where.
And also KARMA already exist as a software, thats the way and the only way it will be
implemented on the MOTIF, as a software, not internaly, there is also KARMA ofr TRITON and M50.
