Novation Launchkey 61 MK4

Fits perfectly into my ableton workflow and works well with the Launchpad to give me more hands on control over my daw. Build quality is very respectable at this price point. The keybed is the weakest link but still feels a lot better than the cheaper controllers out there and is fun to play for me, even having owned a real upright piano. Overall at this price there is nothing to complain about and I see this as a no-brainer for Ableton users.
