The answer to your question is complicated. Lets get the easy stuff out of the way first:
- No external midi sound module for the PC has a MPU-401 midi interface.
- All Roland true MPU-401 midi interfaces, supporting both "Intelligent" and "Dumb/UART" modes are ISA bus-based only on the PC.
- Only certain games require the presence of a true MPU-401 interface. Almost all games that support General Midi, Roland GS or Yamaha XG will work on a UART-only midi interface found on the Sound Blaster 16 and cards of a similar vintage.
- A Roland LAPC-I contains an MPU-401 interface and the equilavent of the Roland CM-32 LA sound module on an ISA card. (CM-32 is 100% compatible with the MT-32.)
- An Roland SCC-1 contains an MPU-401 interface and the equilavent of the Roland CM-300 GS sound module on an ISA card.
- A Roland MPU-401AT contains an MPU-401 interface and a connector that supports waveblaster-compatible midi daughterboards.
- On the above cards, the interface will allow the sending of the midi data to the onboard midi sound circuitry and to any external modules connected to the card at the same time.
- The Sound Blaster Pro and older cards use a different midi interface incompatible with the MPU-401.
- DOSBox can emulate a true MPU-401 interface well enough for any game that supports the Roland MT-32.
- Neither Windows nor Windows games care a whit whether the a sound card supports intelligent MPU-401. Only DOS-only games may care.
- The only games you need to worry about that may require a true Roland MPU-401 interface are games that support the MT-32 and do not support General Midi.
- Some games, Sierra adventures for example, have a fan patch available to allow those games requiring a true Roland MPU-401 interface to work with a Sound Blaster midi interface.Does that sufficently plug the gaps in your knowledge?
If I have an A2000 with an A2286(8Mhz) Bridgeboard.
What should I do in order to get the MT-32 working on the PC-Side?
Three ISA-PC-Slots are available with the current setup:
- 08Bit Multi/IO (LPT/COM)
- 08Bit CT1350b
- 16Bit VGA (ET4000)
According to your info in this thread there is no way to connect this setup to a MT-32. No external connection and the CT1350b is incompatible as you wrote above 🙁
If I put a Midiquest in it, I'll have to take out the CT1350b because the other stuff is needed seriously.
Perhaps I could use an DAC on the LPT port, but a lot of stuff does not support the DAC, but the CT1350b.
Keep in mind, that there is only 8Mhz/286 and the LPT is an LPT2-Port because of the LPT1 is the one of the Amiga side which is no real LPT and useless for the PC-Side.
