My first impression is the key touch..I don't even have to turn the power on..
I really do not understand a player that says the key touch does not influence the ability to play better...both emotionally and dynamically
It has been my number one concern with Yamaha keyboards..mostly the PSR line up, but the Tyros never did it for me either,,Yamaha's mid priced workstations are also bad key feel..
The Roland Juno line (except the Juno stage), are the worst of Roland's line up..The BK5 is a shade better, but still lacks what I want to play..
Korg does not meet my needs either with the PA800 and lower models..where the PA1x and 2x and 3x..are fine (Fatar action)..
If a player spends any time on The Roland's G series (800, 1000,70..or VA76)...it would be hard to switch to any other feel..The high end Korg and Roland arranger keyboards are the most appealing key feel..
Like Dave said..the enjoyment level rises with a better feel under your fingers
