I don't imagine that the combination of features, ease of use, and price point for the BSP will ever exist in a eurorack format module, even though the 3 sequencers it embodies could be described as rather "vanilla" compared to what is available in numerous eurorack alternatives. It undoubtably does appear to be a great piece of kit that excels at supporting a modular synth system.
As a self-proclaimed newbie (only around a year) with eurorack, I am still busy learning about and enamored with all the possibilities for various work flow scenarios within the rack. I think my hesitancy with getting a BSP is the, perhaps unfounded, idea that it might take me out of the rack to some degree. As a bass/guitar player, I've been into stompboxes for years. So, I tend to associate my synth rack with the idea of a pedalboard. It's typically awkward to integrate an external processor with a pedalboard. Granted, integrating the BSP with eurorack seems to be seamless. But I still get the feeling that it will draw a piece of my focus, physical, mental, creative, away from and out of my rack. And right now I am really into "the rack."
Of course, I may also be obsessing and overthinking the whole thing, too. But that's kind of where I'm at... for now, anyway. Certainly enjoying the debate ITMT. Could be a game changer if Emile takes a swing at the BSP, though!
