Ah ok sorry about the KSC thing, I went too quickly past that bit. Makes sense now.
As for the piano stereo=>mono, seems another misunderstanding. I would also like a dedicated mono piano (or mono mode) in SGX-1. One that is better than the Oasys mono piano

I would actually just try using one side of the spectrum when needing to run mono, but I suspect that would give major issues with leslies and auto pan effects on other sounds. Maybe it's worth a try.
I just checked the spacing issues, I don't really have time to go through all of them, but for instance B two octaves up from middle C is more to the left of the spectrum. Or rather, more in the center while the notes around it are more to the side. There are a couple of other ones that are more subtle, basically stereo placement doesn't feel entirely linear along the keyboard. In general I feel the spectrum is a little slanted to the right side, it seems to be already on the right hand side of things an octave below middle C. I don't know if it's intentional?
EDIT: talking about preset A000 btw. I'm assuming it would then be present in at least all German Grand programs.
By the way I am entirely splitting hairs of course. I won't stop using my Kronos if this never gets "fixed". Just something I noticed.
