So, if you need a small, affordable, dependable controller for recording instrument sounds, and you're an avid iPad or Android app user, the Irig KEYS will do the job!*If you search the IK product reviews on Amazon and find a bunch of my reviews, please note, I am reviewing everything I own because I've had IK Multimedia products for some time

These are all standard fare on bigger keyboard controllers, but are lacking, or or severely limited in portable keyboard controllers

I'm also happy that there isn't a lot of noticeable latency, allowing you to play and record in real time, especially when those fast runs for keyboard solos, or banging out drum patterns can get out of sync if your controller isn't super responsive
