Has anyone ever accidentally route a bunch of tracks that were already assigned to a bus, to another bus?
 
If you did, how did you undo it?
 
And..... WHY isn't it possible to undo I/O routeing in SONAR???

Select all the mis-routed tracks, then hold "ctrl" and change one of their outputs back to the bus they should be routed to. They will all change back.

Doesn't help if they were going to different buses, which I'm assuming is the issue.

Correct. It's a bunch of tracks in a mix that was routed across different buses until I used Ctrl on what was supposed to be only the 4 selected tracks but somehow turned out to be all the tracks.

There is no "undo" function for in/out, routing assignments in Sonar.
 
However, if you have "Auto Save" feature turned on, you would have previous version that you could fall back to.

This is a problem. Obviously.

Just a note quick to the advice above.  I believe you must hold CRTL *before* starting to select tracks if you want to move them all to a bus.  I understand that doesn't help if they all have different destinations.
 
 

I don't think you need to hold CTRL until you actually change the bus assignment, although you could of course use CTRL for non-sequential track selection too.

You don't have to use CTRL to change on bus assignment.  If you want to send a lot of tracks to one bus (like assign 10 drum tracks to one drum bus) without having to use the drop-down over and over, you press Control, click each track, and keep Control down while you make the bus assignment.

I'm saying you don't need to hold CTRL during selection, you can just swipe along the quick select in track view, THEN hold CTRL while you change the bus assignment for one of them. You only need to hold CTRL during selection if you're selecting non-sequential tracks.
