I don’t know if “Youtubers” give that impression of every product. Even if they did, I personally would rule out anything that “just makes sound” to revolutionize anything, unless maybe it’s a completely new way of making sound.
But I’d argue that some devices (one might call them grooveboxes) have the potential to shake things up for some of us if they bring a certain workflow and package of features to the table. I’d argue that OT and DT did that, and OP1 did that as well. Probably Push or Maschine as well, MPC certainly has. So you could expect XY to have that potential for some of us as well. But you have to decide for yourself how it could change your workflow to help you make better music. There’s certainly a lot of things it can’t do and a lot of these were known from the get go. So it’s always good when something new is announced to think about how it would benefit or hamper your way of making music and looking for specific features that are important/dealbreakers for you instead of being led by what nice things the Youtuber can do.
It’s unrealistic there will be the one device nowadays that will change everything for everyone, there’s an abundance of cheap and expensive music making hardware and software out there, so it comes down to personal preference what works for you.
Personally, XY has some features that make it very appealing: sequencer based workflow with useful performance functions, sampling and sound engine in one device, it’s small but still has keys and they’re even velocity sensitive. But my impression so far is that I’d stumble upon UI, limited engines and lack of “traditional” MIDI and audio in- and outputs. So I’ll stick with click clack boxes for now.
