Thank you, but it seems you did not get to test what you're saying, in this file, right?
As I said..."I tried the following with your MIDI file..." Worked for me. However, I
should have mentioned something that's often been discussed here in case you missed it: SONAR won't delete something that's not there. The tracks that didn't move started
after the space you wanted to eliminate.
I just dragged one of your short MIDI files into tracks 9, 10, 11 and 21, but a more obvious way to see if there's nothing in the track is to hold Ctrl and set the Edit Filter to Notes. Then just click anywhere in a track's empty space within the section to be cut.
This is an annoyance but once you know about it, you can do the workaround. Hope this helps!
