Midex 8 drver

I’m not there yet, but I’ve had experiences with Windows upgrades in the past and it has worked so far.

Try setting windows to allow installing unsigned drivers.

If that doesn’t work…sometimes drivers are bundled with ‘installers’. The installer might fail for some reason, while the driver itself is perfectly fine. In this case, if the drivers are not packed in some kind of exe archive, try using the Windows device manager. Point it to the directory with the inf file(s) and see if windows can install it that way.

If the drivers are packed in some way that you cannot extract them, then you can usually find them in the driverstore of your working PC with an earlier version of windows.

So…find the driverstore directory of a PC that has the functioning drivers. Copy the whole folder (for the device that you need) to the desktop of your new Windows PC (don’t try to copy it to the driverstore directory of the newer Windows installation straight away…just put it on the desktop or somewhere handy).

Use the windows device manager to ‘locate’ and install the drivers from this copied folder. Once it’s installed, you can trash the desktop copy.

If that doesn’t work…you might also need to use a text editor to change the .inf file of the driver. Look for references to Windows versions and change those to later ones. I.E Some time ago my Roland XR’s USB MIDI driver stopped installing from Windows 8.1 forward. In a Roland XR USB MIDI driver’s .inf file, I found:

;; Windows7
%RDID0045DeviceDesc%=RDID0045Install, USB\VID_0582&PID_006D ; FANTOM-X

;; Windows8
%RDID0045DeviceDesc%=RDID0045Install, USB\VID_0582&PID_006D ; FANTOM-X

and added some lines:

;; Windows7
%RDID0045DeviceDesc%=RDID0045Install, USB\VID_0582&PID_006D ; FANTOM-X

;; Windows8
%RDID0045DeviceDesc%=RDID0045Install, USB\VID_0582&PID_006D ; FANTOM-X

;; Windows8.1
%RDID0045DeviceDesc%=RDID0045Install, USB\VID_0582&PID_006D ; FANTOM-X

;; Windows10
%RDID0045DeviceDesc%=RDID0045Install, USB\VID_0582&PID_006D ; FANTOM-X

From there, I was able to install the driver using the Windows device manager. I never could get the Roland ‘installer app’ to work, but it worked if I found the XR device in the Windows Device Manager, chose ‘locate driver on disk’ (or something similar), and pointed it to the directory with the *.inf and driver files. Windows found it and installed it.

If you edit an inf file, again, you’ll need to allow Windows to install unsigned drivers. Once the driver is installed, you can usually turn that driver security back on, as the kernel binary parts of the driver might still be properly signed and make it past all the security checks/tests on boot.

Hello folks,

I had to update to Win10 (64) and now am unable to get my Midex 8 to work.
Getting the driver was an adventure in itself, thanks to the strange decision to keep an f t p-server in 2023, and I hope I got the correct one:

I installed it and connected the device, Win recognized it with some Bings, but that’s it.

In the Device Manager I have to ‘show hidden files’ that under ‘Sound Controllers’ the ‘Steinberg Midex 8 Win64 Firmware Loader’ appears, but device status tells me the device is not connected. No other (regular) driver appers under Device Manager.

Has anyone any clue what the problem here might be?


Try a different USB port, or try connecting the Midex via a hub (sounds crazy, but sometimes works!).

The Midex is a USB 1.1 device, and in my experience it has difficulty connecting to newer hardware (USB2 or USB3). If you have an old USB hub it seems to act as some kind of “compatibilty layer”.

I have 4 x Midex 8’s… Great work steinberg… Unusable, and crucial hardware always unsupported. No drivers available anywhere… No customer loyalty etc.

TYPICAL terrible and pathetic non-service. from Steinberg. Jesus! Why don’t you just pay someone a few quid to write the drivers, and then we’ll pay for the downloads.?? (It’s not effing rocket science!)

I’ve wasted hours trying to find win 10 drivers for Midex 8… What a stupid way to run a company, who’s software users regularly pay out loads of money for Cubase updates… (I’ve paid very many thousands since Cubase on Atari ST.)


Why? They’re here, and if you click my avatar, I’ve even set it as my “Featured Topic”. It’s also literally the first hit you get when you Google.
