Screen/system responsiveness

[ma]

In an (early) Krome video, I believe even a promotion video, the piano roll screen was looking slow, somewhat unresponsive.

I like responsive systems, so I watch out a bit for gear demoers who quickly decides to do something (some touch gesture) a second time, because something went a bit wrong. Or just how it looks.

Is the Krome among the responsive or the not-so responsive workstations from Korg? (among Krome, Kronos and PA)

Sorry, should try go into a store.
Thanks for reading, kind regards
