Thank you Brad for this help. By the way when I have a saved project that used your MIDI installation patches for PX55S, everything is working except if the keyboard already has another selected patches on its midi channels. In this case ( I am using Cubase) I need to go to each midi in Cubase and select the patch again that send this message as MIDI to the keyboard. So basically at the start up of Cubase, the MIDI patch changes does not send to the keyboard. Anyone has the same issue? Perhaps it is related to a setting in Cubase. I have the same problem with CC messages in Cubase that does not send it to the keyboard
