The Tyros5, 76 key...judging by the excellent demos...is easily the best Yamaha keyboard to date..

I can notice a improved sound over the acceptable Tyros4..

The piano, is better...the guitars, thanks to the amp simulator are excellent..the drums sound completely different...most of the sounds are great...

Although the organ mode is good, I think it is much more Wersi organ and Vox sounds...the B3 sound is lacking a bit to me...but still good..

The Electric pianos I heard did not inspire me (surprised)..

I should say I have never seen a bad Suds-Clavier demo..they do excellent demos....the real test will be hands on and comparison to my bench mark

The first Tyros and 2, and 3...I never cared for ..Tyros4 was getting there....and Tyros 5 seems to be better than any Yamaha keyboard including their WS too..
