Slightly puzzling. Friend has a "black box" MIDI to USB interface. Works fine, sort of. Hauptwerk computer is connected to a Johannes (at his church). The above MIDI box has worked fine as a MIDI input device. It appears similar but smaller to a MIDI Solutions box, Labeled only In and Out with a USB connector and 2 - 5 pin MIDI/Din connectors. (USB powered) It's not a MIDI thru device either.
Hauptwerk recognizes it as USB MIDI In and USB MIDI Out. MIDI in is ticked and works. However, when also ticking USB MIDI Out, there is no (expected) MIDI output from the Out connector. Using Midi Ox (actually Midi Yoke) you can replicate/duplicate/bridge the MIDI In signal to the MIDI out connector just fine But of course, Hauptwerk sees it as the MIDI ports being used by another application. Obviously we want to see the Hauptwerk MIDI out, not the MIDI In. I just wanted to make sure the the MIDI Out of the "black box" was "capable".
Disconnecting - deleting the "box", rebooting with the box reconnected, Hauptwerk again sees it, but with both the MIDI In and MIDI Out ticked, there is no MIDI output. (No Hauptwerk warning of MIDI feedback either). The plan was to connect an external MIDI sound module (Rodgers MX200) to the "Black Box" MIDI out jack, which I do all the time at home, but I'm using a different MIDI interface. Could there be some internal "connection" in this box (causing MIDI feedback) that is "bothering" Hauptwerk? It is sealed, and I didn't want to hack into it.
All fingers point to the "black box", however when it is connected to another application (synthesizer), it works (In and Out) as expected. We have several work arounds, if needed, except using the existing box would be the most convenient. I should add, the same above situation exists whether anything (MX200) is connected or not. There is no external connection back to Hauptwerk either from the MIDI Out of the "Black box". The MX200 is working fine. I also used a scope at the MIDI Out connector. Flat line.
mentioned in another post, the expression pedals of this J are also connected to the amp modules and offer no MIDI output. Definitely not a swell box simulation..
