<<2. iMate. driver 1.75. connected the logic dongle on the 2nd Usb port - like the griffin support told, but during the rebooting i get sys error logs - CRASHES again.>> I've had nothing but problems on my G4 350 (non-Sawtooth) w/ 192meg ram,+ AMT8 + 2408. Especially since going to 4.07. Things seem to be better but still unpredicatable w/ 4.04 (which I've gone back to using). Problems - error 13 or 15 "Logic needs key"........after song boots (using iMate 1.75) - AMT8 (on USB) goes south, disregards all instrument port settings - defined instruments fail to output Midi, all channels on a multi-instrument will work except one The only thing that seems to work is trashing Logic's preferences, then building the enviroment back up from scratch. Opening any "infected" song is definitely a no no, importing objects from older 4.x songs is risky. When I need to get work done I end up doing it on my Wallstreet laptop (which seems immune). Hopefully 4.1 will give us back something stable to use on the newest machines. I don't really need any more features (I've got more than I use right now), I just want the reliability I loved back in the good ole days. Ron Lakewood Productions
