NEVER do a ‘google search’ for drivers – there are lots of dodgy sites out there which will try to tempt you to download all kinds of things from them. If your device is not plug and play then you will need to go to the manufacturer’s site and download the correct drivers. Especially in Windows the native drivers can be missing or corrupted and may need to be re-installed. If you still think the keyboard is not connecting correctly, then there is a useful post here on the Numark site which will help you to troubleshoot your plug and play device.
And you might also want to refer to our detailed step-by-step video course on how to record your digital piano or keyboard. If the above has not helped, then refer to our detailed post on MIDI connection. It is also possible to test your MIDI devices if you navigate to Mac’s Audio MIDI Setup Utility If you are on a Mac then the SNOIZE MIDI Monitor software does a similar job and they have nice documentation on their site on how to use it.
Although it is referring to an M-Audio device you can use this software with any MIDI keyboard or interface. Then if you want a step-by-step guide on how to use it, this page on the M-Audio support portal is great, with easy to follow screen shots.
