Transfer 1.4 Manual?

Aside from the (scant) Transfer 1.4 notes, is there actually a manual, with full documentation anywhere?

Also, when transferring Projects for back up on my computer, I’ve noticed that if I transfer multiple projects at one time, it RENAMES each project, with a numerical prefix (ie. 004 Project Name, 005 Project Name, 006 Project Name. etc).

Seems really odd. Will this screw things up if I ever have to restore any of these backed up projects? Should I manually delete the prefixes?

Oh, and is there a one-step way to back up ALL Projects, Sounds and Samples in one go?

Yes.
From the support page on Elektron’s website:

Yeah, thats the notes I was referring to.

Is there not a manual?

There are English and Japanese manuals on that page if you are able to scroll down a bit.

Ah! Thank you!
