Hi Jambro

!
1) I suppose the .webloc extension is here because of the drag and drop. You should download the files on your hard drive and then import them for here into Logic. You can do the first part by right clicking on a colored rectangle and choosing something like "Save the file as ...".
2) When you delete a track with the 2 fingers swipe, there is nothing left on the flash drive. Except if you have saved your loop of course. If you are talking about RAM, the OS will manage it itself, so you don't have to worry about it.
3) Yes, there is a way ^^ ! Check the section "Camera Connection Kit" of
this post. Thanks for recalling me to update it

.
4) Thanks for your kind words !
Happy looping,
Raphaël
