To my astonishment, I plugged in a Midex 3 and Windows 11 25H2 automatically downloaded and installed the driver.
I did not manually install any driver for the Midex 3.
I have tested it fully and will do the same with my Midex 8 as soon as I can get it out of the bin …
(and yes, I know both devices are no longer supported by Steinberg)
So, the Midex 8 does not work on Windows 11 25H2, whereas the Midex 3 does!
This raises some interesting questions, for example
In other words, the Midex 3 is effectively plug-and-play and fully functional under Windows 11. I will assume there was some signing process whereby the Midex 3 driver was submitted to Microsoft and made available via Windows Update, and if that is the case, can the same not be done for the Midex 8?
UPDATE: incredibly, by browsing to the Midex 8 drivers downloaded from the Steinberg FTP site and unzipped on a local drive, I was able to now also get the Midex 8 working on Windows 11 … I know I tried this last year with the first experimental builds of Windows 11 and it did not work, so I can’t explain what’s happening here, but I’m happy!
This looks very interesting. I recently had to take a Midisport 8x8/S out of my system due to a driver issue that occasionally froze Cubase during startup. I have a Midex 8 somewhere. It didn’t work on my Win10 machine (I can’t remember why), which is why I never tried it on Win11.
Your install shows a driver version (1.9.40.4), which is not shown on Steinberg’s ftp site. They only have a Midex_8_1800, Midex_8_1903 and a Midex_8_1964 folder.
Can you confirm that you used the InstallMidex8.exe installer extracted from the Midex8_Vista_Win7_x64_driver.zip file in the Midex_8_1964 folder?
Also, did you use it for long enough to confirm its stability? I’d give it a try.
You can use Windows Explorer to browse the FTP site, but you may need to type the full URL:
… or copy the line below, and paste it into the Explorer address bar:
ftp://ftp.steinberg.net/Archives/Hardware/Midex_8/Pc/Midex_8_1964/
You need the following file:
Just drag and drop it to a local disk, and unzip it. I did not run executable InstallMidex8.exe, instead I used Device Manager, Midex 8 properties, to browse to that folder and update the driver from there. Once installed, it forces a reboot, after which the Midex 8 worked perfectly.
I also got it to work on Windows 10 using the same method. I’ve tested it extensively, including running multiple sysex dumps simultaneously. For me, it’s now working flawlessly. I even checked with the new Microsoft MIDI stack, under which it’s now even multi-client!
Thanks, that’s the version I have, I’ll try it tonight.
