Old hardware, and midi instrument. . .

Anything that doesn't fit into other topics goes here!
Wife just bought me an old Hammon VB3 organ, now to find out if the Roland Super MPU SMPU II AT ISA MIDI Interface works with Linux, and LMMS.
The computer interface was sold with the organ, as a package.
Cool ! fingers crossed.
The Roland Super MPU SMPU II AT ISA MIDI Interface, for some reason all I'am getting is analog sound output, and I can find it with no problem with Audacity. I'am doing more trouble shooting to find the midi output. I may need to fined ALSA drivers for it.
I gave up on the old Roland MIDI interface, and went with my trusty iConnectMIDI4.
The only issue is now it finds the upper, and lower keyboard, but my foot keys are not working.
I guess, I have more trouble shooting to get the old Hammon VB3 organ, working with LMMS.
