I downloaded the complete Tyros3, Tyros2, and CVP-509 factory preset styles.

They sound super good in the Tyros4, and in the case of the Tyros3 styles...these sound even better than they do on the T3.

Diki is right about the swell pedal...almost totally necessary on the the SA organ voices, like WhiterBars, AllBarsOut, ProgRockOrgan, ClassicBars, JazzRotary, and RockRotary, to name just a few.

Also works with the orchestral SA voices like RealStrings, ClassicalStrings, LushStrings, the various SA Brass and Horns, and the synth sounds, which are from the Motif.

The "out of the box" sound is excellent...never had to tweak anything, even the OTS from the Tyros2/3 styles; the styles from the CVP-509 needed a few changes, but nothing serious.

I'm using a pair of Yamaha MS60S powered monitors, and the Tyros4 sounds BIG, but yet, it can still be delicate and sweet sounding.

I have two demos scheduled for next week...back to practising.
