Hello Thomday,
[Topic moved here.]
To add to others' replies, Hauptwerk can also output MIDI control change (or NRPN/RPN) messages directly from any of its virtual expression pedals. Just make sure you have the appropriate MIDI OUT port enabled (on the 'General settings | MIDI ports | MIDI OUT ports' screen tab), then right-click on the desired virtual expression pedal, select 'Adjust MIDI/trigger settings manually ..., and configure the appropriate MIDI settings on the 'Primary output' tab).
It would probably be preferable for an expression pedal indicator to be driven by MIDI output from the virtual expression pedal in Hauptwerk, rather than directly/electrically from the physical expression pedal, so that the indicator would show the true position of the virtual expression pedal (which might sometimes be different from that of the physical pedal, for example if you've just loaded an organ but the physical pedal hasn't yet been moved so as to send any MIDI messages).
Best regards, Martin.
