thanks reefer. i work with TDM HD2, G5 dual 1.8 ghz, 1.5 gb ram and OS X.3.6, PT 6.7 cs2. i'll try to send all the tracks to a bus and record like you do, i've done it in the past, but i don't like to re-assign manually 40 tracks to busses... is there a way to do it from the HW prefs? I've tried, but I cannot assign multiple HW outputs to a single stereo SW pro tools outs...
