Hallo, as i have just write in other threads around here this is my combination.. not full 100% crashless, but let's say acceptable for me: 10.4.9 pt7.1cs10 logic8.0.1 g5dual 2,5ppc hd accel2 i'm using l8 since a month, there's a weird solo routing bug, also logic control has some new issues, also i had to chenge some option to get my drag'ndropped audio files ask me again if i want to convert to split or just load. i've done some tracks using esb extensively without too much problems and few crashes.. let's say once every 5 hours.. i've just changed my hardware last week and tomorrow i'll start using core audio+tdm with adat 24in+24out (motu2408 for core audio and legacy adat bridge + 96 adat for tdm) hope everything will work fine, i will finally use tdm like i always wanted, esb is a bottleneck!!!
