I have recently upgraded to Logic 5 Mac and now have midi error problems. I had a super stable system with 4.8.1 and have not changed a thing in my setup otherwise. I am working on a track I started in 4.8.1 and have opened in 5, so NOTHING new has happenned except the software and driver upgrades. Two midi problems happen now:1. I get a message saying "midi error" and lose midi input from my master controller but Logic still sends midi to its Audio instruments and to my external synths (but wont receive midi from the controller). 2. I get no midi error message and just notice that Logic stops receiving midi. My controller is OK because I can see on the MT4 that it is sending midi, but the midi doesnt get to logic from the MT4. If I disconnect the MT4 from USB and reconnect it I am back on line again. Seems to me to be something like a driver error or similar? I have the latest Unitor driver installed. I am running unified virtual and classic midi engines. Can anyone give me any suggestions? Would upgrading to OS 9.2 make any difference to the USB drivers? Mac G4 OS 9.1 LAMP 5 MT4 324 megs RAM TIA Glenn Bartlett

According to Emagic and as of 4/29/2002, Dual processing is currenty acive with version 5.0 on the Macintosh platform. The next release / update for Windows will be multi-thread optimized. So.... -If you have a dual cpu Mac, your ready. -If you plan on building a machine for the land of Windows, wait a little while and you will be able to use a dual Zeon or Athlon MP based system. You can call Emagic direct sales information line at 530-477-1051 for details, or other information. Hope this clears confusion. Ben Campbell
