I’m greedy too. I see the Octopus as a master sequencer in a large setup, where you have
lots of sound sources you want to drive via MIDI more or less solely from the Octopus.
The Nemo is a desktop size model of the same thing, but technically, it has less tracks/pages
so it is less powerful in that regard. I somehow always visualise the Nemo as something laptop
users go for, but that is not neccessarily so. I personally went for the Octopus because I am greedy
and because I could and mostly because it solves my music workflow, making it lots of fun!
