For the price, this is an excellent option.

Plugging in a midi controller makes it a snap to use your mad skilz on the keyboard (or not, but it's easier for most of us).-it's trivial to take a part you've created and throw it on another part-location to double or create tonal variations-the pads can be velocity sensitive or not -- a very nice option for different use

but it seems like the most holistically powerful option for the money

Fantastic -- I was on the fence a long time about this, but finally decided to dig into the ol' bank
