Very interesting George. If they're using Yamaha's version of the Mega Voices they might be infringing upon some patent without realizing it?? Or do you mean "Korg's" 'version' of Yamaha's Mega Voices? To be much easier to play in a live situation is a big plus. Possibly Yamaha's software Engineers could come up with some type of algorithm and provide a 'fix' for the Mega Voices on the Tyros by way of an OS software update so they too can be more easily played in a live context. According to Yamaha they publicly stated that the Mega Voices on the Motif ES were playable. They never said that publicly about the Tyros. To fix that fatal flaw would sure be a tremendous way for Yamaha to show their support to loyal Tyros/Yamaha owners and at the same time stem the tide of current Yamaha Keyboard owners from breaking ranks to purchase a competitors product. Just think, to be able to play the Mega Voices in a Live! situation without ANY hiccups. Now THAT would be something.
Best regards,
Mike
PS: 62 note Polyphony doesn't get me too excited about the Pa1X/Pro regardless of how good it might sound. Especially at that price.

But the Mega Voice's being able to be played live, that interests me.
