I can see how you could manipulate the fade volumes with another time line but its still much more cumbersome than the individual volume envelopes that were in CD4....Are we to assume that that feature isnt going to make it back?
Once again, i really don't see what the problem is with using track volume envelopes. At worst, you will have to add a couple of nodes between songs so that you can change the volume level from one song to the next during the song that comes between them on the other track. Even then you should be able to avoid this by adjusting the volume level of the entire event, and reserve the volume envelope only for fades.
CD-A works in the same way as Vegas, in that the level change produced by pulling down the gain on an event are pre-fx. This will screw up any dynamics plugins on an event if you make event gain changes after seting up the FX.
In the case of the compressor, you could always use it's Output Gain to control the level instead.
Im in the city of Seoul...dont have a studio I just make my own compulation CD's along with sometimes adding in sound fx for the fun of it. But I live close to the COEX...my closest subway stop is Seollung (220) on the green line. Id like to check out what you do at your studio sometime....if you want give email me sometime.
