Random patch and effect changes

[Aardman]

I get somewhat carried away when jamming on my electro 6d so was attributing the occasional random patch change that would happen to somehow I’d accidentally hit one of the live buttons, but last night the drive effect spontaneously engaged when I was nowhere near the upper range of the keyboard. I’ve never seen that before.

I DO play aggressively and the keyboard does bounce a little on its stand when I’m lost in the music so could vibration from my playing account for these issues? I’ve never had this happen on other keyboards.

It’s only a couple of years old and I’m not keen on sending it in for service if I can avoid it.
