It seems Korg have their act together quite well, but once again, don't count Roland out yet. There are still many enthusiastic users, including myself, that consider the G70 the best, all around keyboard on the market. It may not excel as a OMB karaoke machine, but it does a FAR better job than most at covering ALL the bases. Which, if you are pro, or adventurous, it is a strong probability you are going to need...

Pigeonholing yourself by a poor selection of an arranger that fares badly at most thing OTHER than OMB functions is not something I'm comfortable with, being one of the few here that actually DOES 'play well with others' as well as enjoys arranger playing. I'd say both the PA2XPro and the G70 are axes I would be happy to take out on just about any gig, sadly, something I can't say about a 61 (of ANY kind)...
