MPU-401 compatibility on 286

Postby HanJammer » 2019-12-03 @ 14:06

What options do I have when it comes to MPU-401 intelligent mode on 286?
I need it to play around with some early midi software (I own external midi devices - controllers and synths I want to use with that) and to play games on my MT-32. I know about SoftMPU but it requires virtual mode which is available on 386-up making it virtually useless for my purpose. True Roland devices are hardly available and have crazy prices, I know there are modern MPU-401 compatible interfaces (which one is the best?) or vintage compatible interfaces (again, hardly available). I guess I can use some sound cards with proper MPU-401 compatibility built in as well (which ones? I own PAS16, but I guess it doesn't have intelligent mode, right?).
So what's the easiest/cheapest way to make it running on 286?

These would be a good solution : http://www.amibay.com/showthread.php?10 ... ompatible-)-new-black-version-with-Wavetable-header

I'm not sure what are the cheaper options, all of the intelligent mode things seem to be fairly costly.

Thanks, that's pretty expensive though. I bought MT-32 for similar price not too long ago (complete with original manual and so on)...

that's pretty interesting

any chance that it is an open source design?

MIDI Out is what you need, based on your original post. Or do you plan to connect a keyboard to that 286?

MIDI-IN exists and is fully functioning on the DB9 port but like derSammler mentions is it not needed for playback/games so the cables come configured as OUT ones unless requested otherwise.

I occasionally see MusicQuest cards going cheap locally, usually from musicians not into retrocomputing who just see them as no longer useful old crap. Managed to nab two that I'm very happy with.

Well... I mentioned controllers (like keyboards, sequencers) - that implies midi-in is needed... :)

But if it does have midi-in then it's something to think about.

I will add this keyword to my watch list then :) thanks.
