No other MIDI drivers.
I have done everything you said, still the same...
What's surprising is that i have installed the drivers on another computer (laptop), same os and it worked the first time.
But during the install, it paused 2 times to ask me something. Once i plugged the KB37, win7 found and installed its driver.
On my desktop computer, no pauses and win7 fail to find the driver...
if u have an idea...
