if had just one keyboard doing everyhing would prolly get a fantom... i dont own one but ive seen cats work with it and it has the most complete all-in one- type of vibe goin for it.. u can even record vocals into it... but for strictly thje sounds I gotta go with my motif es... real clean nice sounds.. people sleep on the synth sounds coming off that board too.. its got the best sounds imo but the interface is a pain in da ass to get around ... my emu pk6 is like the easiest keyboard to navigate around and program.. i wish yamaha had a GUI like that one.. pk6 is also a hot board by the way .. u can find them pretty cheap used.. they are built like tanks too with real nice feeling keys
