Sometimes the best design isn’t always about the sharpest looks or the cleanest lines, as is the case with the Nektar Impact GX61 controller keyboard.

Compatible with Mac, iOS and PC hardware, the GX61 was designed as a no-fuss interface allowing the user to focus on composition and performance.

Number of keys - Most of your options will have either 25 or 32 keys. More keys provide you with more flexibility without having to press an octave button, but you should beware of portable keyboards that include a lot of extra keys that are too small to use comfortably.
Battery life - You don’t need to worry about this too much if you plan on using the keyboard at your desk. However, one of the main reasons to buy an iOS-compatible MIDI keyboard is portability, which makes decent battery life very important. Some keyboards use AA batteries, and others have built-in rechargeables.
Connectivity - If you don’t mind wires, you can find portable MIDI keyboards that will connect to your iPad via lightning cable or the camera connection kit. If you prefer to go totally wireless, look for a keyboard that supports Bluetooth.
