I have OMB and the Motif ES. It works okay, but Rikki is correct about tweaking. Some of the Yamaha styles ( drum voices ) don't play quite right on it, yet other converted styles are fine.

I no longer have a PSR to cross reference quality of sounds, so I can only measure it vs the SYXG50 software XG module that I have. The XG software model is ok, kind of sounds like an older PSR, say the 530, but it isn't the quality of the newer models, like the 2000 I once had.


I can tell you that ES has much more editing power as far as tweaking sounds vs even the Tyros, and that there are some excellent preset voices, but you'll need to tweak away to get them to play with the styles. By default, the styles ( Yamaha and otherwise ), will summon the Motif's GM voices, simply because the Motif cannot recognize the bank assignments used by the PSR styles.

It's a lot of work, so I can't say I recommend it, especially for live play. I think your better off using the Tyros / 3k out of the box. The Motif series actually sounds a good bit like them anyway, if you are just measuring lead voice vs lead voice, although I will say I prefer some of the Motif sounds overall. Still, they all have that 'Yamaha' sound, which I like btw.

In the studio / home setup, OMB can be very useful, but to improve sound quality I think you start looking at high quality samples and different ( non Yamaha ) modules. I have used OMB live, but I use it with my laptop and non Yamaha sound modules, with the Motif ES`as my controller and sometimes the souund source for lead voices. Worked fine too btw.
