The Ketron Event will cost $5,000 here in the USA, and it will apparently be available in December in some countries. I really like the Event, although it apparently doesn't have Seamless Sound Switching/Transition, but of course the Pa5X does. I would rather have a Joystick than wheels, by the way. Since I already have a top-of-the-line arranger i.e. the Genos, I would be interested in a Ketron Event 'module' if Ketron makes one. The module should be more moderately priced too. PS: The Ketron Italy website is unreachable currently, so perhaps Ketron is doing maintenance and updating the website with hopefully comprehensive information regarding the Event including specifications since the Event is now listed on the Thomann Germany website.

I noticed the Event has 216 note Polyphony which is a lot better than the 160 note polyphony of the Pa5X. Better yet, I'll just add the info from the Thomann website.

No Seamless Sound Switching/Transition mentioned, so that's somewhat disappointing. All in all, it seems to be a great option for consideration.
All the best,
