I just emailed Akai about this problem on behalf of the users here and pointed them in the direction of the threads about system test.
I'm sure everyone having the problem has done it too but it's one more to the list so that they can't just fob it off as an 'anomally' as they said to someone.
I also mentioned about the fact that we seem to find bugs with the new OS within hours of it's release and that it should be tested by people who use the MPC properly rather than just giving it a quick skim over.
Is there another email address for Akai support? I'm sure somebody posted one before. i sent the message to
[email protected] but there was another one posted up, akai support USA or something
