A similar muck up was made of the Classic Tracks Window in RealBand where you can no longer use the + and - keys to change data in the various columns such as to Audition sounds provided by a synth in quick succession. Now you have to enter each Program, MSB and/or LSB separately. Very very slow. I can see no obvious reason why a long standing feature should be retrograded in this way.

I noted this during Beta Testing last year and Emailed PGMusic. I received a reply which agreed with my comments, but have heard nothing since. Maybe the muck up will be reversed in the next update.
