Yamaha CP4 Scene Programming

I use a Yamaha CP4 for gigs and want its Scene memories set up so I can switch sounds instantly on stage. The goal is to build custom sound mixtures—specifically:

• Layering multiple instruments (e.g., piano with pads or EP with strings)
• Splits that assign different sounds to separate key zones

I already know the basic front-panel operations, but I’m stuck combining these elements into polished, recallable Scenes and saving them so they load exactly as needed for each song.

What I need from you:
1. A set of sample Scene files (or step-by-step instructions) that demonstrate the layering and split techniques above.
2. Clear, concise documentation outlining every parameter you touch—voice selection, volume balance, effects routing, key-range settings, and any MIDI or controller assignments—so I can replicate and tweak the process later.
3. A brief remote walkthrough (video or live call) to be sure I understand how to store, name, and back up the Scenes on the CP4 or via Yamaha’s software tools.

If you’re experienced with the CP4 or other Yamaha Stage Series boards and can speak the same language of Performances, Voices, and “Live Set” logic, we’ll work smoothly. Please tell me about similar programming you’ve done and how you’ll deliver the Scenes or tutorial materials.
