I want give all those struggling with crashes while using USB/OMS interfaces this information. If you have a USB/OMS midi interface and any currently shipping version of the MacOS this applies to YOU. (Emagic interfaces maybe immune to this??, but it couldn't hurt either.) I was having crashes literally EVERY 30-45 minutes. I was just about ready to take my MidiSport 2x2 into the street and smash it with a sledge hammer. Then I updated my USB support files to the latest developer release 1.4f. The effect was so profound I almost couldn't believe it. I now experience very few crashes. I've only had one crash since I'm probably up to about 20 hours of LAMG use without a crash......... for me this is manna from heaven. Get it here...... http://developer.apple.com/hardware/usb/download_prerelease.html You will need to use ResEdit. and follow the intructions in the readme as the "USBsupport" driver will not function "as is". A minor modifaction needs to be made. (see the readme!!!!!!) It would be a smart idea to make a "safe copy" of this file before you attempt the modification. Get ResEdit here..... http://asu.info.apple.com/swupdates.nsf/artnum/n10964 You will need to be careful. Don't trash the original files, just move them out of your system folder in case you screw up with ResEdit. I know this has be said on the list before. I feel that this is so important that I am re-posting this to the list. I suspect that MacOS 9.1 will contain USB 1.4 so this will not be necessary for long. but i think that USB support is ROM based so there will have to be some sort of ROM update. i really hope some of you have the same results I did. peace
