Hi all, I agree with all those who are saying USB *sounds* wonderful but isn't. I've got a group of students upstairs now running Logic quite happily on ADB/Serial based G3 Beige Macs. Bog standard cheapo interfaces. No crashes In the main studio we're running it through two Studio 5 No crashes (Our Apogee is down but that's another matter). I'm running it at home on a G4 - USB of course Crash city. I sometimes boot Logic and get told that it can't find the MIDI interface. Reboot and its fine. I had real problems getting the dongle recognised...the iMate is now on its own USB port. And now I am assuming its the MIDISport which is connected to the end of the keyboard which is causing the crashes - however their tech support said they have no problems..! (Perhaps someone should email them the thread(s)) I'm running it with System 8.6 Base + MIDISport extensions + SCSI Probe. The crashes generally involve the screen freezing (or perhaps its the Keyboard/Mouse failing) ..If music's playing it will carry on - just can't stop it! Thing is, how do I find out if the MIDISport is the problem? Do I really have to buy another interface just to see if it works!? (By the way, anybody having problems with the MOTU Fastlane USB?)
