(resolved)
Bug tracker is broken, so:
Fails to recognize inputs in right to left order, while same as their execution order, when inputs not issued by trigger. Even routing the inputs through "sync" with "mode all" fails. Causes ghostnotes when used with notein, and other awful sideffects.
EDIT: Actually sync does fix the problem a little bit, but require 1 has to be used instead to fix the retained input. There's no clear reason why it works sometimes and not other times, or why the fix changes.
(on last edit, had forgotten a sync earlier)
It only occurs when an input is processed first.
Demo:
Bang one pair of floats into pack and another pair via t b b.
