lloopp comes in 2 folders:
- lloopp_externals : contains everything except:
- lloopp_presets : contains all your personal presets and filepaths. this folder is empty in the download just provided for new users.

if you want to update:
download and unzip a new version of lloopp, KEEP YOUR LLOOPP_PRESETS untouched.
zip your existing lloopp_externals (to have a backup if something is behaving strange with the update)
then replace(!) the folder lloopp_externals with the one in the update.

old versions of lloopp need to be "out of sight" for the max-application; so zipping it is pretty save.
(also save of course is putting it in some folder out of max' searchpath. but still, if you open one patch from there
then manualy, max starts steering inside there.)
