I find all these sequencers very complementary except for the Eloquencer. I actually planned to cancel the Eloquencer once I committed to the ER101/102, but then figured what the hell, and got it. It’s very nice and intuitive for creating sequences quickly. I like the eight channels. Not sure it’s a long term keeper.
I’m very fond of the quality of Cwejman, and it forms a solid base for even the most tortured noise and ambient stuff. I don’t do much traditional polyphony (or music for that matter) but I often have a lot of voices going on at once, or a couple being quantized through the uScale. Cwejman is also, practically speaking, a good investment.
I generally don’t worry about space because I make very cheap cases for myself - usually the power is the biggest cost to expanding.
I am very interested in the Instruo stuff. Unique, creative… But holding off - I’ve got more than enough gear to learn and exploit.
