A. When running a macro from the MSC400 B. When you send a single command from the remote?
Guess: My thought is everything is assigned correctly in the MSC-400 but the devices are set to ALL in the remote.
This would be true if the MSC-400 macros only flash the right emitters, but every time you press a single command on the remote (i.e. Play, Stop, CH+, etc) all emitters flash.
