Music Creator 6 Timestretching. Need Help!

Podi... welcome

I have not used the time stretching function in any of the cake products I have ever owned very much. (not all products have time stretch)  mostly just to experiment to see if it worked well.... and it did not .... in my case. 

You will get better results with it if the changes you want to make are small. For example in the demo they had in the old Cakewalk Pro 8, they had a radio commercial that was not exactly 30 seconds..... I forget if it was under or over that... but it was by a few seconds..... something like 28 or 33. They used timeshrink/stretch to zap the voice over to make it fit the commercial exactly. 

Using it to shrink a voice over a few seconds is a totally different thing from using it to shrink or stretch music...and the bigger the change the worse it will sound.  IIRC it also had the ability to change pitch. I tried to get it to change the pitch on a song with out changing the tempo....and the result was tragic. 

Quite often the best option is to start again on a new project and recording at the proper tempo (pitch) than to try to use software to alter it. 

Just my 2 cents. 

I think MC would do time stretch/shrink as a "process audio" event.

I haven't used it so I never go to look for it. Usually the MC line doesn't have the features in it that Sonar P does.
