I reinstalled the MIDI Express 128 drivers. Now I can see all MIDI activities in MIDI OX. Still struggling to activate MIDI in Hauptwerk. I used the wizard again. But no action yet in Hauptwerk on the 4 manual Rotterdam Laurenskerk organ. Wondering how to route MIDI Ports/Channels to the manuals/pedal.
In Hauptwerk on the "Audio MIDI Performance" window I can see MIDI activities on the "Console MIDI in" row. Now how can I route the MIDI signals to the 4 manuals/pedal of the Laurenskerk organ?
