This regards a Logic 9 file in which VI Pro is instantiated in 9 Logic Tracks and each track has the MIR plugin inserted into it. I have been working on this file for a few weeks without incident. But then, twice during the past few days an instrument stopped making any sound after I'd been editing its track for a while. In the first case, I quit Logic and restarted the computer and the instrument resumed playing normally. In the second case, quitting Logic and restarting did not make the instrument audible again - - although VI Pro's meters showed its signal. All the other tracks play normally. Does anyone have any ideas regarding what might be causing this? I'd be most appreciative of any help.
Thanks,
Stephen
