Why is it that if I enter a long note which creates a long clip, then shorten the note, the clip is not also shortened ?

I guess because the code looks like:
if(Note.begin+Note.duration > Note.Clip.End)
  Note.Clip.End = Note.begin+Note.duration
without check for the last note ends before the clip end

Is there some purpose for this thread? 

Yes.

Funny but not very helpful Slartabartfast. I ask thinking about the way it used to be before MIDI and Cakewalk. I remember when MIDI came to be and what hoops we had to go through to get it to interface with a computer. No USB. We used parallel ports which meant configuration of the port and the driver. A mistake here meant no connection.
 
A MIDI clip? What is that? A MIDI grove clip totally non-existent.  Now we have MIDI tracks with virtual instruments playing within a DAW able to record the MIDI and also turn it into audio. In the past one needed a hardware synth to turn MIDI into audio. The luxury of Sonar seems wasted on a few. Unless a real problem is found where one simply can't work I suggest getting over these nit picking issues. Do some composing and be thankful you don't have to do it with a pen made out of a feather. 
 
I think one needs to put things into perspective.  

Thanks for your perspective, John.   To answer your question, why mention it?   Because just in case CW is going to actually improve their handling of midi, this 'clip' issue will likely prove to be central.    Did anyone think there would be tens of thousands of clips in a project?  Very unlikely.    Credit to CW -- at least Sonar survives, up until it crashes, with such large numbers.

John, the purpose of this thread is not to criticize how your beloved Sonar handles MIDI in general, and certainly not to somehow say that Sonar's MIDI handling is not an improvement over the dark days of prehistory when dragons roamed the Earth. It is to clarify in the questioner's mind how Sonar will actually respond to what he is trying to do with MIDI. In that sense it is no more pointless than thousands of other threads in this forum. Seeing a false comparison or criticism of Sonar in a simple question should prompt you to reevaluate your emotional relationship with the application. It is just a computer program after all, and you are just a particularly knowledgeable user and generally a respected and helpful contributor to this forum.

You misunderstand me. True, I like Sonar but I have no emotional attachment to it. Not only do have Sonar but other DAWs as well. None of them are objects of emotional attachment. 
 
What a users does is find how to get a job done not spend their time and others finding fault or commenting on non issues.
 
I still don't know why this thread was started. You're not apparently looking for a feature request or a bug fix or even help in understanding a feature. So my question remains open what is the purpose of the this thread? 
 
If its just a general discussion with no purpose as such perhaps it belongs in the Coffee House?

Sorry John, I don't see how a discussion on how midi is handled in Sonar could merit banishment to the Coffee House.
Reading this thread I've learned a bunch of things about how midi is processed in Sonar that I didn't know before.

I think lately willie's been trying and this question/thread is IMO appropriate. Defined and coherant questions that seem to serve an educational purpose. Polite responses/followups. I applaud that.
 
OP has had a bit of a past of crying wolf and being a bit infuriating though so there may be a bit of frustration on John's part.
 
I know OP has certainly made me pop a couple times.
 
Didn't even want to post in here but yeah, credit where credit is due and a bit of understanding for the guy who's had to deal with the aftermath of a LOT of dumb/annoying threads.
 
Back on topic...

OK if this is what the members think and I have reason to believe it is I will back off and not comment in this thread further.
I also appreciate the willingness to speak out if things seem unfair. That is very helpful to me. Thank you.
