Cannot recognise MIDI device

[gormster]

Probably not the sort of question you're used to hearing on these forums, but they've been great help to me before. For some reason, one day MPU-401 (the windows MIDI driver) decided it would stop working on my PC. I'm assuming something changed - but things always change, so I've no idea what it was. I de- and re-installed the device, (actually it's three devices, but you get my drift), and it still reads Error 10 or Error 12. It has a conflicting IRQ channel when I first install it, but then I change said IRQ channel and it still won't start.

I'm running:

OS: Windows XP Home SP2
Devices:
Game Port for Yamaha
MPU-401 Compatible MIDI Device

gormster,
I'm not really in a position to be of much help here, but a few things come to mind...

"actually it's three devices, but you get my drift"

Probably you'll attract more interest and get more informative responses if you provide more specifics.

To which three drivers, exactly, do you refer? An internal Windows driver supplied with the OS or a "Windows compatible" driver supplied by a 3rd party? What, exactly, is not working? A software interface to an internal sound card, the OS interface with an external MIDI device, or what? Through which piece of hardware? How is it connected? With which device(s) is the IRQ in conflict and when was/were this/these installed?

Have you tried to get the Windows MIDI player to play the sample MIDI files through your internal soundcard, checked control panel settings, etc? Have you verified that the problem is not in your external gear by feeding it a MIDI signal from elsewhere? It's amazing how many "MIDI not working" problems can be traced to a simple oversight on the part of the user. A MIDI device is "listening" on channel 3, for instance, and the sending unit is "talking" on channel 4. I don't mean to suggest that this is the most likely answer in your case, just that from the information provided, such an explanation for the silence you likely hear cannot be ruled out.

Granted, my questions are very general in nature, even silly, perhaps, and reveal a lack of understanding about the specifics of your problem and what you've done to troubleshoot it and narrow the possibilities. That's my point, actually.

It's actually nothing to do with MIDI, per se - it's just that a MIDI device happens to be using this game port. The problem is that the drivers listed at the bottom of my original post are not starting, and I was wondering if anyone else has had similar problems with these drivers and was able to fix them.

Device Manager Errors.

10. This device cannot start. (Code 10) Device failed to start. Click Update Driver to update the drivers for this device.
On the General Properties tab of the device, click Troubleshoot to start the troubleshooting wizard.

12. This device cannot find enough free resources that it can use. If you want to use this device, you will need to disable one of the other devices on this system. (Code 12) Two devices have been assigned the same input/output (I/O) ports, the same interrupt, or the same Direct Memory Access channel (either by the BIOS, the operating system, or a combination of the two). This error message can also appear if the BIOS did not allocate enough resources to the device (for example, if a universal serial bus (USB) controller does not get an interrupt from the BIOS because of a corrupt Multiprocessor System (MPS) table).
You can use Device Manager to determine where the conflict is and disable the conflicting device.

Uh yes, did already know and try this.
