Korg nanoKEY 2 white

It's useable as a portable way to quickly play some ideas, but not a replacement for a keyboard. Two main problems I have with this unit:

* The velocity sensitivity is basically non-existent. Of course it's there, but the way the "keys" (or buttons) are made makes it impossible for me to play with a velocity I want.

* The modulation button is a binary switch (either on or off), so it's impossible to use any given amount of mod except for no modulation or full.

I can recommend it if you need something to throw in a backpack to be able to plug in to a laptop or iPad and save a musical idea. Wouldn't use it to perform or play for pleasure.
