Howdy,
I'm trying to set up this editor from 1988 called OBIEX which was written for the Oberheim Matrix 6R and 1000 rack analog synths.

It's got a simple, closed circuit vibe to it, so I'd love to get it working.

But I'm having some weird problems.
I can initiate a Patch Dump Request from the editor (the Matrix 6R starts the dump) but there's no response in the editor.

Changing parameters also has no effect.

I'm doing this on a Pentium III WIN98SE and a Yamaha WaveForce 192XG PCI sound card with DOS MPU-401 support. See attached photos for details.
Is my card on I/O Port 332h because of its physical slot on the mobo?

Tomorrow I will connect MIDIOx or MIDI Monitor to the old PC and see if there's any data.

Here's a link to the program if someone wants to check/sniff it:
