Is it possible to open a midi in format 0 as I don't want  loads of midi tracks on my screen. I saved the midi  as Format 0 and opened it again but it always separates out the midi.  When I do an import its says format 0 track 1  but once imported  it splits out the tracks.
 
If don't see a CAL that can do that. Anyone got some wise words on this?

Would using a track folder suffice for not wanting all tracks visible?
 
Mudgel posted a massive CAL compilation a bit ago. I am no expert of them either, but there are quite a few folks in here who are.

You can just select all, copy, and Paste Special to a new track, choosing the Paste to One Track option.

+1 to brundlefly's post.  He is spot on.
 
Here is a link to the Sonar documentation that describes importing the midi file so that it is placed in the project as a single track:

Please note that Sonar MAY sometimes have issues with proper playback of midi files, if everything is all in a single midi track.
 
They talk about this condition in the documentation, and here is the link to that, as well as the resolution of any such playback problems:

For whatever the worth, I sometimes play wedding receptions and such, where I am doing solo keyboard work during the pre-dinner seating, and all that, and I frequently play keyboard parts live, alongside projects with a bunch of midi backing tracks, to give a nice full sound, and I find it WAY easier to manage it all with everything split into separate tracks.  (I have nearly 1500 midi files set up as Sonar projects that I keep in a sub folder in my main Cakewalk Projects folder - I found all of these available for free download from the web, or I built some of them, for some of the progressive tunes).
