after reading many threads and watching Phil's videos about the topic, I get myself all necessary devices to connect my Retro PC to my Laptop for GM and Roland MT32+ playback under DOS 6.22 and Win 98 SE.
I got the UM-ONE mk2 first, but after setting everything up, the UM-ONE didn't show any incoming signals and the Falcosoft Midi Player doesn't play any sound. Using UM-ONE as output device seems to work as the signal LED on the UM is blinking. Even tried different Soundcards (SB32 PNP with 2MB and YAMAHA Audician 32 plus) to no avail. Using different Gameport to Midi cables also didn't help. So I wondered, if the UM's input might be damaged and I got one of the cheap USB Midi devices.
The cheap device also doesn't play back any sound, but unlike the UM-ONE, one of the LEDs lights up only after connecting it to the Retro PC and the Falcosoft Midi Player is actually showing a constant Midi In signal. MIDI-OX is showing a constant spam of "Note Off" and I don't know if this is normal. No change though when playing back MT32 or GM.
I also tried SoftMPU with and without setting the IRQ to 9 or 2 but to no avail either.
One interesting part is the AWEUTIL GM and MT32 emulation, which causes the PC to reboot when trying to run King's Quest IV with MT32 or Duke3D with GM emulation under DOS. Monkey Island 2 on the other hand works. Under Win 98 SE MI2 and Duke3D both work with via SB32 and Audician GM emulation but sending the signals to an external devices also doesn't work.
The system is a P233 MMX on one of the early ATX boards (GA 586 ATX v3) with a Voodoo 2. It doesn't seem to have any other problems.
Havn't gotten a wavetable module yet, to these are working at least.
I really don't know what the problem could be. None of the threads I read mentioned such a problem.
