Funny you ask…I happen to have one of these on the road with me right now. My large rig (Motif, Hammond, Leslie) is in the back of a semi-truck with my main band while I’m out with this other one.
I do like the Native Instruments integration, I’m not crazy about the keys. I like the weight (its only 22 pounds I think) and the LED lights behind the keys. But I wish there were more assignable buttons. If you get one, get the 2.0 new one that has a physical mod and pitch wheel if you use them for synth-ish kind of stuff.
The learning curve for how to get this thing communicating with multiple plugins inside MainStage, Ableton, or Logic is a little steep. If you have any random specific questions about it, I’m happy to give my opinion on things.
The biggest question is ‘what else should I get’? Or 'would you recommend this?..its hard to say without knowing specifically what you want it do.
