I needed versatile midi controller for Sonar but didn't want to spend loads of bucks on some fancy hardware.
Well if you have an iPad (2014 on) and a Windows PC running Sonar then this project will set you up with a state of the art wireless midi controller. Play the keyboard or kick off sounds with drum pads or control effects with sliding faders, oh and its portable too, runs off bluetooth not wireless!
Open the guide and work through it step by step, you can use any midi controller app in the App Store but I choose Midi Controller because it beats everything else hands down.
Shout if you get stuck, have fun!
