I got some inside information today from an old friend that used to work for GEM in the Netherlands and has still many friends in the arranger buiseness..
As to what to expect at the musik messe he got all excited. He could tell me that there would be new arranger stuff presentated by Roland, Korg and Ketron and that there would be a new brandname entering the arranger market that would make a huge impakt on the total market.
Just tought i's share this with you, sadly he could not give anymore information as he didn't know much more himself.
