Although the software makers had talked about releasing some worksheets to transcribe patch settings, I have only recently found them online (taken from the Korg DS-10 performance guide book--now if they'd only release that in English):
http://doronpa.voxx.jp/ds10/download/pdf.htm. As these are specific to the DS-10 features, I'm finding them more helpful than the blank MS-10 templates.
For a poor person's 'undo' function, I keep a preset slot labelled 'Temp' and store my current patch there before I fiddle with it.
