Does anybody have any info on this MPU-401 clone?

I am guessing it is using that adapter like that Music Quest card, of which this one seems a clone of.

Interesting. Never heard or seen that one before. It would be interesting to learn whether it is intelligent (Music Quest PC MIDI Card clone) or UART (Steinberg clone). 😀
Frederick Pohl's Gateway , configure it to use MT-32 and see if it craps out with an error
Silpheed is also highly sensitive. 😊 Make sure the card is configured to IRQ 2/9 and I/O 330. Make sure no other cards conflict with those settings. Good luck! 🤣
You can already test whether it is intelligent by just launching the games. When they launch with Roland MT-32 configured that means the card is intelligent. When the game freezes it means the card is not intelligent. 😀
Stojke, you can try the schematic I posted on the Music Quest mpu thread... it would also help to post a photo of the backside to see what pins are connected on the DB9 port
Alright, this is what happened:
1. The only cards in the system are Matrox Mystique and DX-401
2. DX-401 is set to IO Address 330H and IRQ 2
Using Microsoft resource tool, MSD, i have read that IRQ2 is redirected to IRQ9, because IRQ2 is reserved for Second 8259A.
When i start Gateway (I have installed the game by selecting MT32 as the Music device) it works with out problem, no freezing and the game accepts commands.

Can you please give me the link Keropi? 😀

I will try to test it with Silpheed now. Should i expect the same thing to happen as with Gateway (Freezing if no Hardware Intelligent)?
Great news then! I don't know about Silpheed but Gateway displays an error dialog if it cannot access the mpu.
The link to the thread I mention is here: Music Quest PC MIDI Card MPU IH9MQ9 : info , drivers and tests
Silpheed also works 😀
Here is the back side mon: http://puu.sh/aqxyJ/41a5a8e698.jpg
So Gateway will display that when the MPU-401 is absent (broken card) and when an Non Intelligent model is used?
yep, Gateway will display an error, you'll immediately know if the mpu works OK or not...
you can also try Wing Commander and see if it works in the intro, there is a chance of crash after the fireworks, look at the MQ thread
looks like the cable from the MQ mpu will work on this one too

The card is mentioned here:

This is from 1991 so this aligns with the other intelligent MPU-401 clones released in the 1989 - 1992 period. 🤣
Some other anecdotal information:

It is. However: it is a clone without box / dongle / manual / disks so retail value is probably around $75 to $100. 😵 Still a very nice find though: especially since it expands the intelligent clone list from 3 to 4 manufacturers.
don't sweat the software stuff, it's nothing important... you can surely read the ROM but you need a programmer and desolder the chip
