Thanks but it is a pretty straight forward process, like I say names and samples transfer fine, they just write over each other.
It seems to be a file name issue, this maybe why it seems to load some samples and not others for people.
Might not be C6 but the midi sample dump protocol that is the issue.
Thankfully I’m on a Mac and had forgotten I can batch rename with Automator.
I have just changed the names and they load in order now.
