Well, sure enough, that did it. I can't believe I didn't try turning it off, but that's all it took. Turn on the SC-88, with none of the four lights set to on, and the MT-32 turned off before starting up Dosbox. Plays GM in games like a champ. Both my desktop and modules are on a side table, with …

So, essentially, since they are on the same channel and the MT-32 has no mute button/switch, the only way to avoid getting sounds from both at once is to turn off / unplug the MT-32 completely (else turn the volume all the way down via either knob, I suppose).

Just had a thought... previously when I did a device check, the MT-32 (or whatever) MIDI device showed up as device 3 and that has been my mididevice=x standby in the dosbox.conf templates that I've been recycling each time I write a new shortcut for a new game. With both now connected, will both be …

So I've chained my MT-32 and SC-88 together, with the SC-88 connected via a m-Audio MIDI-to-USB cable in the MIDI IN receptacle, to my Windows 7 PC with a RCA-to-stereo 1/8" headphone jack, plugged into the L and R RCA outputs on the SC-88, into the line-in/mic port of my X-Fi sound card on the PC. …

I did see the references to daisy chaining the modules and will need to try that out. Currently I've got one plugged in at a time, then I swap cables. A real good idea. I've been tempted to run the midi module through my stereo amp, but the current setup isn't working badly at all. I think I'll …

Nice. I was rather elated. I'd been wanting to get my current gaming PC up and running as a hybrid old/newfangled gaming platform for going on six months, but had been forced to use an XP machine with my MT-32 until they got their ducks in a row regarding drivers. I will say that they certainly …

While this was certainly an issue at one point, they finally released a Windows 7 64-bit driver for the m-Audio USB Midisport Uno cable. Works fine with both a MT-32 and a SC-88. This driver might be new as of October or November. Functionality is surprisingly seamless, and it has been working very …
