Saving stuff to floppy isn't too tricky.

You need Double Sided High Density 3.5" disks, i.e. standard PC floppy discs. However that the TS12 floppy disc format is not compatible with PC's so I'd start with a fresh box of reputable unformatted DSHD floppies and I'd format them all on the TS12 before doing anything else.

I always have "Keyboard Naming" turned on (third page of the System menu)

The "Storage" section of the manual covers things; I'll try to summarise.

To get to the "Disk" operations menu press "Storage" then "Disk".

The disk menu has all the facilities you'll need.

To save - click "Save". On the save menu you have to select the type of information that you want to save. You'll be saving "120 Programs" "120 Presets" "60 Seq/Songs" and "System Setup". You may want to save "SysEx Banks" "Sample-Banks" and "Sample-Edits"; you may need a stack of disks for the Sample stuff!

So to save each type of info, use the "File Type" button to select the information to save, then click "Save". Confirm this with "Yes" then you'll have to enter a filename and reconfirm.

When saving sequences yuo have the option to embed the programs within the sequence data. This can be good if you change voice in support of a specific song / sequence but in your case don't bother!

Hope this helps!
