Hi, Mike (and anyone else who'd like to weigh in on this) - Just received my PX-5S on Monday. Within 5 minutes of playing it, I was on the phone ordering a custom-made gig bag. GREAT instrument! I'm still having a problem wrapping my brain around the concept of Stage Settings, and how they interact with Tones. I've done lots of online research, checked out the videos, manuals, etc., but the documentation of this concept is still rather sketchy. When you state (above): "Other companies may calls these Performances, Setups or Registrations but the concept is the essentially the same" - that is crystal-clear to me. I've been a longtime Kurzweil user, and am intimately acquainted with "Setups," which is their terminology for Casio's "Stage Settings." BUT, with Kurzweil (and other manufacturers), Setups are a separate mode from "Programs" (or "Tones," in Casio's terminology). Maybe it's the user interface, but with the PX-5S, It appears that I can be in Stage Settings mode, yet scroll through Tones and hear them separately from the obvious, massively layered/split Stage Settings. I'm just not grasping something that I'm sure is very simple; could you please enlighten me by walking all of us slowly and clearly through these concepts, and explaining the interaction/differences of Stage Settings and Tones so that I'm able to better understand the architecture of the instrument? I think many would benefit from a thorough discussion of this topic, as I've only seen it touched on briefly in a few places. Thanks very much! Oh, and did I mention that I LOVE the PX-5S? Great job, everyone! Dan
