@Popsel Hi
Well, to be honest I've not looked yet at how tones are stored, I had just a quick look some time ago to what the Sample Manager stores but since a tone has many more parameters than a pad data I've started from them to try to understand the logic behind.
I hope to map the pad data in a week or two since I'm quiet busy with my real job now...
Btw ZTN seems not much different from pad data, just more complex because of the more parameters & eventually custom samples with velocity triggers, etc...
I don't know why the Sample Manager cannot reopen tones coming from the MZ-X, I never tried.
I'm pretty sure that there is some sample data conversion (compression) between SampleManager->MZ-X and back, maybe we cannot reopen tones because a bug or by design.
Maybe the Sample Manager cannot decompress sample data... who knows... we need to investigate
