Editor issue:
if you are "losing" info- that simply means you are not saving it before you move on... EASIEST fix. Go to the config screen and put a check next to "Auto-Save". OR, on the toolbar- press the auto-save button and a check box will appear. This will let the editor save everything for you as you make changes and change presets, songs, tabs, whatever... as long as you "change" from where you are- it will automatically save your edits. That will solve your problem right away.
ALSO- there are two modes for the editor. ONLINE and OFFLINE. When ONLINE (SYNC'd with LF)--- all presets, songs, etc. will comes from the LF as its currently programmed. All changes will go back to the LF. If you have edits in memory and then SYNC- you WILL lose them as it will pull the data from the LF every time you change.
So either work offline, or work online. You can also save things to the LF, do partial dumps, full dumps, etc... you have loads of options... just pick one type of editing per session so you don't "overwrite" things by accident. Once you get used to that- there is a LOT of power in the editor beyond simple editing...
hope this helps. Enjoy the Liquid-Foot Jr.
