Hi
I'm running ProTools7.0 on a 12" 1.5GHz PowerBook G4 with OS X 10.4.9 and 1.25 GB RAM and media on a firewire drive.
My problem is that for no apparent reason I suddenly lose the connection to the MBox2 and with a click the speakers are silent. I currently only have 2 instrument tracks open and was simply selecting a different patch on Absynth when the connection failed, so I'm not overworking it! This was also an issue on the previous version of OS X so I don't think it's that.
Because I'm short of USB connections I have a Belkin Hub connecting midi keyboard and ilock but the MBox2 is connected direct.
Any suggestions as to why this connection keeps dropping after 10 - 30mins?
Many thanks
David
