Minitaur Logic Loop note freeze

Hi there,
one last question about my Minitaur :wink:
Sometimes i already have the hanging note problem with Logic 9 and X.
It happens if i record something to logic in a loop.
If the loops starts again (so that logic will playback the recorded notes)
and i try to overdub, the Minitaur mostly freeze and plays a hanging note.
Without loop recording (Overdub) it seems to work fine.
I have to turn the unit off and on to stop it.
Everything else is working.
No matter if editor is open or closed.
Connection with usb.
Latest OSX.
Any Ideas ?
