If you like to play piano, and will use pianos/EPs in your music you won’t be satisfied until you have an appropriate board. I’ve gone through this many times and after failing to be productive with makeshift options finally bought a nord for “playing”. It’s not considered part of the synth stable, which for many of us flip every so often. When I think about the $$ I wasted by not just buying a good DP to begin with…

But, if you’re just looking for a nicer controller, screw that and get the A4K. The sequencer will change your writing. Based on gear you listed, maybe you could sell the vermona and pick up the A4K and PX-5S.

FWIW I definitely preferred the sfx-6 to the sfx-60 plus controller, even though you don’t really lose any functions. Just felt more like an instrument I suppose, which is why I waited for the A4K.
