FIRST, I also have NEVER understood why EVERY keyboard that has the potential of being used LIVE does not have a stereo pair of XLR outs.
For $1500 to $3500 (estimated cost of MANY of our keyboards and arrangers in todays market) you would think that we wouldn't be forced to work with direct boxes at every gig. XLR outs are a NO BRAINER.
And secondly, how does any company, say Yamahas new Tyros 2, try to promote to their clients that they have a killer vocal processor, harmony or other wise, and NOT provide an XLR in (with or without phantom power...but why not add the phantom power???). I believe that ANY and EVERY board that tries promoting that they have built in vocal processors should have a COMBO 1/4" and XLR input jack. ANITHER NO BRAINER. Don't make your clients pay over $3000 (Tyros 2 and others), and then have to go out and buy an XLR to 1/4" adaptor.
I know you asked for NEW features, but as few copies seem to make logical choices on the inputs and outputs it seems as thought this NEEDED posted.
