Our church has an Allen MDS-6 organ with stops for MIDI on Great, MIDI on Swell, and MIDI on Pedal. I connected the organ to my laptop and I can successfully use the keyboards and pedals on the Allen organ to play my virtual organ in GrandOrgue - using the laptop's speakers. What I really want to do is play the stops I select in GrandOrgue over the Allen organ's speakers. Is this something GrandOrgue is able to do?
The Allen MDS-6 has four MIDI ports, In, Out 1, Out 2, and Thru. Out 2 is switched - you have to put down the MIDI to Great/Swell/Pedal stops. The manual, on page 13, says, "Under normal circumstances, MIDI sound modules should be connected to the switched MIDI port labeled MIDI OUT 2... Devices such as MIDI sequencers should be connected to the unswitched MIDI port labeled MIDI OUT 1..."

In Midi & Audio Settings, on the MIDI Devices tab, I check the box for mio 1 in the MIDI Output Devices box.
On the Audio/Midi menu, I went to Midi Objects. For the Swell, Great, and Pedal, I went to the Send tab and set Device to mio 1, Events to 9x Note, and the channels to 1, 2, and 3 (to match the channels listed in the Allen manual.)
With the cables, I've tried various combinations of Out 1, Out 2, and In on the Allen organ to In and Out on the laptop. I can always get GrandOrgue to recognize the manuals and pedals on the Allen organ, but I never get the MIDI on Swell/Great/Pedal stops to play anything from GrandOrgue.
So is there some quirk to getting this to work? Or am I trying to do something that can't be done?
