This happened to me a few times.. Seems like certain UNASSIGNED notes of my keyboard like to stick some parameters of modul8, most noticeably the "stil"button. I see it as unpressed and the global speed is at 32, but the movies are still stuck. Happens every time I press certain keys that are not assigned to anything! These keys also like to change some rotation values.
Can you send me your midimap (pref of modul8 or project file in file mode) ?
You can also check, with the module "print direct event" to show wait exactly is sent to modul8 from the midi.
