Anyone else experience this? I've just updated LAP from 6.1.1 to 6.3.1, and updated my MOTU drivers, so it seems like something's probably set improperly in a preference I've been unable to track down. My computer is used -only- for studio, so I'd hope there aren't System Extension problems to worry about. Any insight is tremendously appreciated. I'm relatively new here, and LUG looks like a great resource. Hope to contribute something useful myself. The setup: Mac G4 733MHz LA Platinum v6.3.1 MOTU 2408 mkII The symptoms: 1) Logic hangs indefinitely upon attempting to merge audio. I launch Logic and work on my session, making edits to (comping) pieces of digital audio. When I try to merge audio and create my "final take," Logic hangs, forcing me to do a hard reboot of the machine. Note: If I quit Logic and then relaunch the application, I can merge audio, if I do it first thing. 2) Logic sometimes hangs indefinitely if I Close a song within Logic without quitting the application, and attempt to open another song with File:Open. 3) Reaction time gets worse the longer I have a session open, and the more I do sample edit operations (i.e., takes longer and longer for a Sample Edit window to open, then takes longer for graphics to catch up to playback within the Arrange window). ====Jeff Elbel PO Box 1222 El Segundo, CA USA 90245-6222 - Ping's new "Loyal To You" CD available now via Marathon Records http://www.marathonrecords.com/order.html Proceeds benefit Habitat for Humanity. __________________________________ Do you Yahoo!?
