I think you nailed it man — this would be an outstanding first Elektron box for someone new, it would give them an amazing overview of sounds/features from this corner of the music-making world. But for folks who are already immersed, it may not offer enough new stuff to justify a purchase.
I’m very grateful for my little Elektron collection and stoked for anyone who jumps in via Syntakt. Going to be a lot of great music coming out of it, no doubt about that.
