Depending on what you are looking for in a controller, I seriously don't think Windows 7 64 bit, or Vista 64 bit, would give you any problems.

The SOFTWARE that comes with it might, but I don't think the actual device will.

You can look for USB, which are often 'class compliant' or you might also look for some with a MIDI interface, which needs you to buy a midi interface, usually usb.

Now, if you're looking for one of those controllers that have all sorts of knobs, buttons and sliders, it may be a bit more difficult, since you need to configure those. If you're looking for a plain 61 key controller keyboard, I don't think you'll have any problem getting it to work with Win 7 64 bit.

From M-Audio's website, if you're interested in their Keystation keyboard controllers:


*The following class compliant (plug & play) devices can be used without installing any drivers under Windows 7 32-bit & 64-bit.

Connect your device and Windows will install the drivers automatically. If prompted to search for drivers, browse your computer and choose to search your main system drive (usually C:\) to find the drivers.

I'm blessed watching God do what He does best. I've had a few rough years, and I'm still not back to where I want to be, but I'm on the way and things are looking far better now than what they were!
