This is kind of where I’m at too. I’ve received pushback on this position (3 is enough), but IMO, owning the DT/DN/ST is a lot of sonic power, and adding any more Elektrons on top of those wouldn’t have as much musical ROI for me. If I grabbed any of the flagships, I’d have to look at them as upgrades and one or more of the Digis would have to go. Analog Rytm? The DT (and maybe ST) would go. Octatrack? DT would have to go. Analog Four? ST would have to go (although some of the digital machines are dope). I think the only survivor in any of those scenarios would be the Digitone due to its unique versatile approach to FM and easy polyphony up to 8 voices.
That being said, it’s all hypothetical since for the time being, the three Digi boxes really hit my personal sweet spots of power vs ease of use. With the exception of sound generation and voice management, having three boxes with basically identical UX is incredibly easy on the brain/muscle memory and accelerates things when I just want to get down to business making music.
That said, hard to fault anyone for wanting more Elektrons. They ARE dead sexy, and I get that some folks are more “collectors” than I, or maybe have more enjoyment from learning new boxes, or even have more varied complex music making needs than me, such as using the OT as a mixer and in support of more complex sampling and effects needs.
But personally, three is a magic number, yes it is.
