Thank you for a great reply! It was very helpful.
I totally get the idea that it's a lot of money for just one functionallity, when the Elektrons already have very powerful sequencers. The reason I'm thinking about Bloom as an alternative, is that I would like to have the opportunity for creating happy accidents, to create music more intuitively. I've been interested in Marbles earlier, but I think Bloom might just be a little more interesting. I've just looked a little into the Squarps, but don't know a lot about them. But from what I understand, they are similar to the Elektrons (at least the Pyramid), that the sequencers are very powerful (when you know what you want), but perhaps not as intuitive as Bloom (when you want to just follow the flow, and see where it takes you).
I've also been very interested in Eurorack for a long time, so this might be a way to start. I could then add, say an 0-coast, which would be a cool combo with the Bloom.
