UD, true, but the PSR3000's key still feels rather spongy (=less responsive) than on the Tyros. Quick 'key response' is IMPORTANT for producing 'musical expression' especially when playing & articulating melodic phrases , especially on uptempo tunes. I'm not knocking the PSR3000 (great sound & features, especially considering its bargain price), and also acknowledge shared key feel gripes I have with BOTH the Tyros & PSR3000 (namely Yamaha arranger's smaller key 'size'), but for whatever reason, I've been able to adjust (adapt) to 'that', but NOT with the prior.

As far as the key throw (distance between the un-depressed key position & the key fully depressed), has anyone here actually made measurement comparisons? I'm curious to find out what the real measurable difference is in inches.
