Hi Bill,

I'm trying to be as unbiased as possible (you know I'm a Yammie fan), so here's my summation.

The conversions are pretty darn good, although it sounds like the converted styles are substituting a steel string for the "Mega Voice Nylon String" in the originals, giving a slightly thinner and harder(twangier?)sound.

Perhaps the Wersi nylon string guitar, if that's what was substituted, has a different timbre than the Yamaha voice?

I did notice an absence of fret noises and other characteristics(especially so in the Flamenco)that give the Yamaha mega voices their uncanny realism, although the dynamics seemed to convert pretty good.

These two styles are factory presets on my S900 and I did a comparison using a set of Yamaha headphones.

Still, the conversions were much better than I expected, better than others I have heard.

I want to thank you for taking the time to create the demos and post them for me.

Ian
