Funny (...) to see that no one complains about the price of the PA5X 76 in relation to its bugs and its complexity...
and that the majority of criticisms come from people who do not know Ketron brand and have not tested EVENT (or another Ketron kb) in real life...

just have a look at Bartłomiej Krzemiński videos; he owns other kbs too… but doesn’t seem to have problem with his Event.
On Psrtutorial, everyday brings false info: one user keeps saying there is no registration button on EVENT...

About complexity and usability, keep in mind
1 once you save your registration, you load it with ALL the environment necessary to play easily and smoothly,
as you prepared it before … and recalling it needs just typing two or three numbers.
2 the footswitch (ie FS13, not available on other brands) puts at your toetips 'buttons' not available on the kb (neither on other brands) ;
see user manual page 159: not new since Audya…

As for Ketron users, they keep waiting their Event kb : they already knew that bashing experience when Audya came out.
I will never say Korg or Yamaha are not good but, given what I know and have seen (videos and mainly real life)
about Tyros, Genos, PA4X, I know, despite their respective qualities, the ‘environment and philosophy’ is too different from what I am used to

When you use a brand for years (Yamaha, Korg), it is not easy understand another ...; same for Apple ... or cars...
even less when you don’t own one model of this other brand and never tested it personally…
Ketron is a little brand and can’t pay for talented demonstrators showing what few user will be able to do;
but Ketron users know … for years. To each user his needs…

Hope I am not dumb nor ridiculous...
