I’d use it as a long-form compositional notepad with the OT and the rest of my Elektrons. Develop 16-beat phrases, play them into the RK008, play back through the synths while tweaking, etc.
This is what I’m hoping for too. I would really love to be able to use it as a scratchpad for things I write on the op-1 and can then bring to life later. If it works well enough, I would be able to let go of my op-z. That’s how I currently use the Z but I really don’t like to play on it.
