Trying to Export then Import a Session State fails to reload all the existing patterns. In my case 8 patterns exported, only 2 restored after import.
The patterns are correctly restored after reloading the Ableton Live project (*.als) though.
I can provide the session state XML if needed (but I’m not sure if the 8 patterns are actually saved or if the issue is at loading time).
