works perfectly for midi
I bet the 1 star rating is for someone who tried to use it as a printer cable...
I'm using this cable from my digitakt directly to my iPhone 6 and it works great! (Make sure overbridge is off on digitakt and usb midi is on). Good length, perfect fit. Cant comment on durability since I just got it. A perfect example is running korg gadget. I can run 8 different synths and drum machines in there with midi cc and each on a seperate channel and program the whole thing from digitakt in my case. The limit is pretty much that of your phone cpu and the device sending the midi, and of course 16 midi channels. For the price of the cable it's a huge way to expand a portable setup.
This cable is perfect for my iPad 2 and Casio keyboard. No extra adapters needed. I plug the lightning end in my iPad and the other directly into my keyboard. The Playground Sessions piano lessons app works great!
I used this to plug my casio privia keyboard into my ipad. Works great, and it detected it immediately. This is exactly what I wanted.
Received a midi keyboard and didn't want to pull out laptop or plug into comp. Purchased this wire and worked like a charm with my iphone 7. Just plugged in, turn on garageband app on the phone, and start playing on the keyboard. AWesome!
