Hello, I hope this is the right place to post. I am having some I problems with my Akai MPD32 midi controller that I have never experienced before. I use Windows 7. I cannot seem to get the MPD32 to send any midi data or be properly recognised in Windows. I plug my MPD in by USB and don't see the device connected icon but the MPD is getting power. I've tried running MIDIOX to see if any data is being sent but when I try to select the MPD32 port it says "Undefined External Error". I've looked in Devices & Printers and the MPD is listed there and is apparently working properly but something's really not right. I tried on another computer with Windows 7 on and it recognised it. I installed MIDIOX and was able to select the MPD input but the monitor was not showing any data at all. I thought maybe it was the USB cable so I went to my local internet cafe to see if they had any but they didn't, although they did use my cable on a printer to test it and it was working fine. Now I'm completely lost and don't know what to do. What does this error mean, I can't find much about it on the internet. This midi controller used to work and I don't know what has happened to it now.
