[/quote] It wasn't about your Wersi having "better synthesizer sounds" until you stated it did, and that is still your opinion and certainly not a fact.

Considering the Tyros 4 doesn't have any synthesis capability and my Wersi has several... Wavetable, FM, Modeling, Sampling, and allows me to stack any combination of these sources, I'd safely say the Wersi does have better synthesizer sounds.
