You could use the nuked sc55 emulator instead of the SC55 Soundfont.

So just connecting the midi port isn’t enough, I have to output the entire sound of my laptop to my old computers line in? Is that because it’s playing the sound through my laptop? Did actual mt-32s work that way also?

Yes, the MT-32 is a MIDI-controlled external sound module. The controlling computer simply sends a series of simple digital instructions over the MIDI connection, which tell the MT-32 which sounds to use, and when to start and stop playing each note. The MT-32 interprets the MIDI instructions and outputs analogue sound signals on its stereo line-out jacks. These sound signals then need to be amplified, either using an external amplifier or by connecting the signal to the line-in port on your sound card. All external MIDI modules (including Roland SoundCanvas, Yamaha MU series etc.) work this way.

In the case of MUNT running on a separate PC, it's essentially connected up just like a hardware MT-32 would be, with a MIDI input and audio output. You can either have the emulated MT-32 sounds play through your laptop speakers, or connect the audio output of your laptop to the line-in on your sound card for a more integrated experience.

Since you have a retro PC, I'd wager you have either speakers or headphones plugged into the SB16? If so I suggest getting an inexpensive audio mixer.

This will let you adjust the audio levels of multiple devices from a hardware interface outside the computer. This was something that had to be constantly battled with as games and other software just did there own thing and didn't always lets you adjust every channel independently.

I'm talking about something like this that is under $30. https://www.amazon.com/Portable-Channel-Audio … g/dp/B07Y2RYHFF

Well, I have audio-out going into my Retrotink 4k. I want to make sure that the sounds line up for recordings.

These sound cards will automatically play whatever goes into the line in, in dos and windows 98?

Also I cannot seem to find the midi coupler thing that will allow this to connect to my game port, the only thing which might be it is $200 on eBay, can someone help me find the right thing?

Both Serdashop and TexElec have options.

As for the mixer, you have the audio from your PC and your laptop go into the mixer, and then both channels are combined and outputted to the RetroTink.

I found a thing elsewhere on the vogons forum which says "In short the MPU401 (or MIDI interface) of the SB16 isn't intelligent mode compatible. Back in the day when you had a MT-32 you would have purchased a Roland MIDI interface (or a LAPC-I which has everything in one card)."

Just to establish: When I get the game port - midi adapter, and the Roland UM-ONE-MK2 to connect to my computer using MUNT that's all the hardware I am going to need to get everything working, right?

Yes, some games do need intelligent mode MIDI to work. But there's a program called SoftMPU you can run that will allow them to work on your SB16. Only really old games that only support the MT-32 have this requirement. Newer games that use General MIDI don't require it.

The Vogons Wiki MT-32 page has a list of game that support the MT-32 and there's a column that says if they need intelligent mode or not: https://www.vogonswiki.com/index.php/List_of_ … _computer_games

softmpu can output intelligent mode midi from your dos retro pc via a cheap null modem (serial) cable to a modern pc running munt. on the modern pc (win or linux) you can pipe the midi data to munt with a variety of software: roland or yamaha serial driver (win9x), hairless midi serial bridge (winxp or later/linux iirc).
