Bought this to replace one I bought a couple of years ago which died.
The last one I bought cost me 30 quid and worked fine until one I plugged it in and my PC wouldn't see it.
Saw this one and read mixed reviews but thought "well it's only a fiver, gotta be worth a try"
Came on time. Packing was a bit sparse(much like the instructions) but it arrived undamaged so no complaints (especially as the postage was free). USB one end and 2 DIN connectors on the other. Paperwork said plug marked "IN" goes to OUT on your device. PLUG marked "OUT" goues to In on your device. Well that about covers the instructions you get with it. Plugged the USB into a spare socket and the PC saw it immediately so plugged the other ends into a MIDI keyboard. There are various ways you can make this work. In Windows set your MIDI device to USB out. In Cakewalk make sure it is selected as a MIDI device. Either way, the keyboard sprung into life. Tried it as an Input device from my digital drum kit and worked well. In fact,exactly the same as the one I paid 30 quid for. At present it is connected to my Line 6 Pod 2 which I can change effects on my guitar without having to fiddle around part way through a song. Sorry for the long winded review but I think a lot of the bad reviews are because of people not getting the IN/OUT part right or trying to fire more notes down it than their instrument will take. My keyboard has a 32 note polyphony and as long as you keep the output from the PC to less than that, all is well. You cannot physically input more than 32 notes at once when playing a keyboard (only 10 fingers!) so unless you are transmitting backing as well then you will be fine. Latency (delay) is as I would expect but actually better than playing it through a sound card. Well worth risking a fiver for.
