I'd been wanting one since they came out, sorta talked myself out of it, and bought the VCV Rack module instead.
Then I bought a Go case to allow me to move some modules around, but also started moving all sorts of stuff around the studio trying to find a good layout. Been doing that repeatedly, until I recently started thinking about the Go as a focussed system, for heavy droneage type stuff. Decided the core would have to be the Oneiroi. Ordered one.
