Hi Mike. I've still very much 'got L plates' re the PX-5. I'm on the road with Taylor Dayne and the amount of time I can get at my PX-5 is down to minutes before lengthy sound-checks, break time, then showtime. So I really cannot muck around. What I've set up so far works, it's good, and I ain't changing it til I know much, much more! Wisdom learnt from experience. What "seems" to be how it is, is this: I edit a Tone (say, add some chorus and rev to a Rhodes piano).......... it only stays as a "write" save if I save it to BOTH the Tone and the Stage Setting, right? Or ONLY to the Stage Setting? I am not clear on this, and I can't surely say I've tried 1. saving to the Tone only, and 2. saving to the Stage Setting only .............. and getting my edits saved. Frankly I'm confused. So whenever I do anything I save it to both, not one or the other.
