I should clarify my statement Benno. The flaw is not in the Mega Voice structure, ie., "the .WAV sample" but in the 'ability' for the "Keyboardist" to play the Mega Voices in Real Time, ie., -a Live setting. Mega Voices use Velocity Switching but so do Normal Voices also. Depending on how hard or soft you play the Voices the sound quality and/or level of the Voice will be reproduced accordingly. With the Mega Voices however, each velocity range (the measure of your playing strength) has a completely different sound. The Mega Voices incorporate such things as Harmonics, Slide, Hammer-on notes, Muted, Dead notes, Open (hard), Open (mid), and Open (soft) effects. Yamaha specifically states, and I quote: "The Mega Voices are NOT intended to be played from the Tyros Keyboard. The Mega Voices are primarily designed for use with recorded MIDI sequence data (such as songs and styles)."

So all this boils down to not being able to play "effectively and in a realistic Live Real Time setting; naturally - (no Hiccups) type scenario where the Keyboardist would most likely be very embarrassed and frustrated because if he did so, ie., - (play in a live setting, ie. Gigging) he would most likely encounter these unwanted 'effects' when playing them. Now that is not to say these 'effects', eg., Hammer-on notes, Harmonics, Muted, Dead notes, etc. are not constructive and useful in some settings (even maybe in a Live setting) but to be able to play them Live and the Keyboardist to have 'absolute' control of these effects in a Live setting is very unrealistic and hence the reason Yamaha stated so specifically - that they are NOT intended to be played from the Tyros Keyboard itself. On the other hand Yamaha 'specifically' has stated publicly that you CAN play the Mega Voices on the Motif ES. I have played the Motif ES and even owned one for a short while and I can tell you first hand that playing in a Live situation is 'easier' although in my experience with the Motif ES (though I may have not had the Keyboard setup correctly to play the Mega Voices optimally) the Motif ES's Mega Voices still leave 'something' to be desired if and when you wanted to use them for Gigging, ie., "in a Live setting". Still, to have that better functionality for the Tyros Mega Voices would truly be an enhancement and an improvement over the current Tyros Mega Voice playing ability.

Best regards,
Mike

PS: Benno, the Tyros Mega Voice playing ability can be 'improved' by setting the "Initial Touch" to its 'hardest setting' in the Controller Panel. Also the 'Harmony' function can also affect the Mega Voice playing ability.

What say you Yamaha.
