i'm looking to get a controller keyboard fo my MC307 groovebox, nothing to big and flashy, but good enough. Anyone got any suggestions as there's so many on ebay!!

I'd say an M Audio Axiom. Pads, keys, knobs, sliders and a good build quality you'd be able to use it later with other gear too. I'm not sure what size you are looking for though. Does it need to fit in a backpack or just for studio use? I have an mc307 as well and I'd just want some nice velocity sensitive keys with aftertouch. Personally I usually just end up sampling individual sounds from the 307 and sequencing those in a sampler using the built in keyboard.

does the 307 detect velocity & aftertouch?

axiom is cool, but be aware it has clicky encoders.. not everyone likes them. (theyre good for fine parameter selection, but for cutoff sweeps/etc theyre not great)

sweet cheers guys, i've just gone for a simple alesis one, velocity sensitive keys with pitch bend and modulation, don't wanna run before i can walk!

nice one!
