Sorry for originally posting in the wrong forum and thanks to Mac and others that responded. Ihave tried following everything recommended plus everything in the documentation without success. My pat file from BB works in BB fine as well as Sonar. It converts without errors in RB. It is recognized in RB but the patches list is empty. I have reinstalled configuration files many time. Customer support confirmed the same problem using the the same file from this forum and hopefully will continue their efforts. Any one else with this issue? No errors but an empty patch list. Any ideas would be appreciated. having used BB and sonars synths for years I am now sold on both real band and my RD 700 plus real track - but can't get RB to communicate with the RD. The RD is fine with GM but that kind of misses the points. The problem appears to be with either the original definition from this forum or the wat it is converted for RB. HELP!
