This makes a great midi controller for a home studio.

I like that it has a MIDI

I don't use this for Rock Band but rather use it as a very inexpensive MIDI controller for my portable MIDI-enabled equipment.

I got this strictly as a MIDI controller - works great for that

So, for less than $30 shipped you get a nice compact beefy little MIDI controller keyboard that runs on 3 AA batteries.

This is cheapest, velocity sensitive, midi keyboard you will ever find.

I wanted something that was battery powered and had the standard 5 pin DIN MIDI port as well.
