No Master - An Odd Problem

What do you mean by importing old projects? I just open them. They are in Sonar's native format after all. All buses are included.

If it was a Sonar 2 project it is a wrk file and the new buss structure came in Sonar 3. None the less it should have a buss if it did in Sonar 2. It may be that there was no master buss created in Sonar 2. Remember that in those days to create a buss one had to do so and then restart Sonar.   Often times people didn't bother.

Well you could create a master buss in the new X1 project from the old project and select an audio's track output while holding control and selecting the new master buss. All audio tracks will be routed to that buss. Also right click on the master buss and select it as the default buss. All new audio outs will be routed to it there after. A save after will keep those settings.

Quick follow-up:

1-I created a new stereo bus and called it Master.  The way I know how to route to it is to click in Inspector and add a send.  Not sure how the control-click thing works.
2-Question 1: How do I tell the V-Studio that this is now the Master so the master fader controls it?
3-How do I kill whatever output I already have?  Right now, the tracks seem to be going directly to Main.

Everything's cool except figuring out how to assign the master fade on the V-Studio to the Master bus. it happens automatically on new projects that already have the master bus.

This was actually easy to fix once I knew how: 1. The Master fader controls whichever bus is first (on top in track view). 2. If you want the master fader to control a different bus than the first one, just drag the orange WAI strip to the bus you want the master fader to control. 3. Of course, you can go to each audio track and select it to be output to master instead of Mains. So, in the case of project that does not have a master bus, you can rename the first bus to Master, or create a Master and drag the WAI strip to it. Hope this helps someone else.
