Guys,

I'm a little stuck on nomenclature here. Aside from the Keystation having 49 keys and the Oxygen 8 only having 25, why is the Oxygen 8 referred to as a "MIDI Controller" and the Keystation is not? It looks to me like they both do the same thing. Aside from the number of keys, what is the difference between these two:

M-Audio Oxygen 49 Keystation

M-Audio OXYGEN 8 V2 25-Key USB MIDI Controller 9900-41392-00 by M-Audio

Thanks!

Greg
