This error is fixed.
May also solved the other problem as slider 2 got linked to the wrong notifier, quite remarkable because Renoise should have fired the notifier error from the start but somehow the notifier attachment request is probably done faster than the attachment was done .
could this sort of automation be rendered?
Tested it, the groove effect seems rendered…
This is indeed fixed - you still have to select Tools>Groove automater upon reloading the song to initialise it, but all is good from tat point on 
Nice work once again vV and thanks!
Yeah, but the snippet was created for lackluster to work out so i hope he has found a nice spot for this framework.
