NOOOO! fkc NO ! there is NOT any fkn EVENT on the end of taht list. what is the problem with this bunch of nituids
I payed for every update soon 1000$ for a program, that has A LLLLOOOOOT more gugs than this. Just to inform you :a after some updatesw ago, suddenly the the keyboard shortcut for F5 F6F7 F8 F9 F 10 stopped to work. and other things is happening, / is unconveinant compraed to toher programs. thesse day they are bussy with having other programs : Izotpe, / Fabfilter and thousands of plugin to work, coz thats where they get the money..... while the program itself fill up with more buGS !!! I regret  VER VERY VERY MUCH that I started with this amateure program  about 10 years ago !!!!

Old thread, but this has not changed and my answer is what fool does not perform a basic mastering of ANYTHING that leaves your studio. Only a untrained person that's who. 
I often had clients come for a 4 hour session and then want a rough mix to take home. Those do not get burned to CD or transferred to a USB stick with out a quick Top and Tail and check of RMS level. 
I could careless where Sonar puts the start and stop of songs as long as it doesn't chop something off. I've had that happen only on pure MIDI tracks.  I'm always going to top and tail in Wave Lab, takes about a minute to do a quick check over. Always listen to the intro and the outro. And I always balance the RMS level so they get to hear the songs in the car without complaining about loudness issues from song to song. 

There is one case where Sonar projects will never stop after reaching the end of the project. If you are using Midi FX like Echo Delay, which create new midi events, then playback will really never stop (not only not stop where you expected). Other than this, I never had a project not stopping playback at the end.

So I read this whole thread and ... well, it didn't help, but maybe someone has a suggestion for how to fix this my issue.  My song is 64 measures long, but sonar thinks it ends at 95 measures.
 
Bit by bit I deleted everything to see what the offending event was.  I have deleted all tracks and buses, as well as tempo changes, key changes, and markers.  It's an empty project.  But it still reads as 95 measures.  What else is left for me to delete?
 
I know I can work around this by manually selecting what to export with the mouse, but I am lazy.  I'd like for when I hit "Ctrl+A" for it to select just where there is song data and nothing else.

I mix and master all-in-one, and with the exception of a few rare occasions I NEVER have this problem.
 
I right click, hold, and drag across all clips I want to export. This selects those clips. Then I export, and Sonar does just what it should...it exports just those clips.
 
The aforementioned rare occasions occur when I forget to select the clips, which is almost never these days.
 
Also, for reverb tails I clone a track and use it as a dummy. I lower the track's gain all the way, then mute and archive it so I'm certain it won't sound, then position the clip so it ends where the reverb tail should end. Then I make sure to include it in my selection.

That's far too long winded for me.
 
I simply slip edit ANY track out to the point where I'm sure the reverb has stopped sounding as use that as my End Marker

Cakewalk has to offer the opportunity to end a project at any point an user wants.

I never understood this, you put hours of work in to a project but get lazy with setting in/out points ?
its a whole 6 clicks.

I use "select all" for more than just exporting.
 
But usually even after everything is written I spend an hour or two doing nothing but make a minor change (that usually requires deselecting), export,  listen to it in the game or in itunes to make sure it sounds good with gameplay or in a playlist with other music, etc, then change again.  Also since my music has to continually loop and the mouse selection won't work when you mouse over the yellow loop points, I need to disable the loop, then click, then re-enable the loop, or else send an end marker (which will have to change if I lengthen the piece) and click on that then do the select from=start, thru=end.  So I end up doing this over and over.
 

I just had another project that this happened to (i.e. deleting all tracks, events, tempo changes, etc. still does not affect project end).
 
There is a couple of things I did in this project I didn't do in others.  I had to copy an instrument track from another project so I saved out a track template from the other project and loaded it into this one.  Then copying and pasting the automation wouldn't work unless I split the instrument track and copied the midi track and synth track separately.  But when I re-assembled using Make Instrument track, that automation would disappear from view but still affect the synth.  Another user explained that unless the "Synth Automation Track" dropdown in the synth rack is set to the MIDI track, any automation on the synth will disappear, never to be accessed again.
 
Although I did do this step, I wonder if there isn't more data that disappears whenever you split/make and instrument track.  Perhaps these automation lanes get saved, hidden, remaining even after the track and synths are all deleted.
