Sure - here's some details. I don't put Tones in Zones 1 or 2 becaue I reserve them for Hexes. When I put the first piano of the Casio (GrPnoConcert) in Zone 3 and use it's DSP for EQ, the settings don't consistantly update when I switch to that Stage setup. It's weird because I can go into edit and see the numbers that I used, but they're just not working until I change one. Then it snaps into place. The LFO bug is a little different and probably not applicable to the vast majority of PX-5s useres. As I'm sure you know there's no source-destination modulation matrix per se on this keyboard (which is perfecly fine on an instrument of this type since it's basically a piano) but in Hex you can do quite a bit with the LFOs because it's a very flexible section of the synth engine and you can set their speed to zero. So (for example) I can mix the levels of the second layers of Hex 1 and 2 separately by modulating the amplifier of one of them to a pulse wave set to zero. You can't differentiate two layers with the sliders if they are the same number but in different hexes, which is why this is a nice thing to be able to do. This works great by the way! I do it all the time. So I tried the same approach in a Tone but this time my purpose was to keymap a sample set to a different location. This is a type of thing many of us do who are into rompler sound design. So I found out that even though LFO edits (and all edits for that matter) are offsets in Tones, while editing I could still bring a pulse wave to a dead stop! Fantastic I thought.. I pulled the adjacent sample set over the afflicted area that I wanted to change, retuned it, and it sounded perfect! That was until I saved it anyway. After saving, the pulse wave always had some movement to it (which wrecks everything) and I tried several times. I'll try to post a file it it would help but I'm just not able to do that right now.
