Oh man, I was worried no one was gonna join lol. Anyhow, welcome and hope you have fun! :) 

I have the PO-12 Rhythm and the PO-20 Arcade. The arcade has been a boon to my sound design with retro stuff. The rhythm has been just what I need for easy drums combined with my all analog signal path Korg Monologue. Now just to start implementing the Emu Proteus 2000, pick up a drum synth, another sequencer, a mixer and a few fx units and I'll be doing awesome. Really my current process has been to not spend too much time on fx and design, and just keep going. That way I get lots of stuff recorded. I can always mess with it later in software. It's been super good for my workflow.
