No the keys are not nearly as heavy as the PA4X; they are a lot like the EA7 keys, but little more solid, with aftertouch of course.
Wow, that’s great. Look forward to hearing some recordings? We hope.
Does it have a lot of the country styles? I rescued quite a number from earlier model T’s ( though you probably have them anyway) they sound quite good on sx . So if of any use , let me know.
