Driver & editor installs OK. Device shows up on list during install. However, editor cannot "Receive ALL", as Also, device does NOT show up as a MIDI device.
Went into device manager->sound video & game controllers->Korg MicroX->Properties. Here, the General tab shows "device is working properly" but if you click on the Properties tab, then select the Kork USB-MIDI Driver for Windows, then click properties, a window opens up with this:

As you can see-- "Status: driver is enabled but not functioning properly"
Also note the two radio buttons that aren't labelled with anything. And the "settings" button does nothing.
It's clear the problem here has to do with the MIDI driver, not the editor.
Or, I suppose something that needs to be set in a certain way on the Micro-X but that isn't-- yet I've been unable to find any indication of how you need to set the microX for the editor to work, if there are any particular global settings or whatever, except for the "Exclusive" box being checked (which it is).
I don't see anything in the editor regarding configuration or anything in the driver config program that allows for testing of the connection or anything, and the error I get tells me nothing regarding what may be wrong. In the device manager the device does NOT show up with a yellow questionmark, so it is recognized. Also, the driver config in the control panel does list the device, which shows Midi port 1-IN, 1-OUT and Status: as "Self Powered". Also, in control panel Sound and Audio Devices, hardware tab shows the Korg MicroX on the list, with "the device is working properly" but this is essentially the same place where the properties tab lists multimedia devices which when I select the korg driver & click properties I get the box pictured above...
Seriously disappointing. All this power here and I can't use my computer with it...
Also, it was some challenge figuring out where to go to ask questions. The Korg manual and readmes that came with the software had no reference to how to get support at all. And their website sent me to the page for downloading PDFs of the manuals I already have. I finally tried to google "Korg software support" and found this site.
I'm thinking I may try to install the driver that came on the CD with the product-- perhaps the older release will work better in my case. Also am wondering if using a non-USB Midi connection is compatible with the editor. IT SHOULD BE, if not it's a poor design, IMHO. If USB is the only way certain critical editor functions can be performed, it's an incomplete MIDI implementation and a sign of lazy engineers or programmers. Here's hoping anyway, as the problem may simply be USB and if I can just bypass it, it's annoying but a workable alternative.
Which raises another question-- I don't want to start editing on this thing until I can backup all the factory default programs and combinations. Anyone know how I can sysex this stuff into my computer via MIDI while I'm waiting to figure out what's wrong with the USB connection? A more complete MIDI implementation document somewhere?
