How do I get rid of repeated notes/adjust all velocity at once?

I have not worked in MIDI for quite awhile, but if I remember correctly, just click on one of the repeated notes not at the end or beginning of the note (the beginning is used to move the note and the end is used for the length of the note) but somewhere also where it is not on the other note, and I think right click and then delete the note. If deleting both notes, you know you always have Undo and ReDo and a History on the Edit menu that you can redo (bring it back) if you mess up.
 
The other question about the velocity and changing all notes I am not sure?? Is there something up top of the view (perhaps Piano Roll View - I am not sure what view) where you can select the channel of the MIDI the notes are on and then edit the velocity like editing a word document or so like that, except with Midi notes.
 
Ah, someone else may have to answer that, but I think there is a view where you can add Control Messages and such, but all I remember is doing it by Event List view and going through every note. I think there is an easier way though. May help to look at the Help Section also to find out how to do stuff. Once you have learned it, then you will remember it and if using it, will be quicker at getting editing done.
 
Well, that may not be much help but perhaps, someone else will give an answer also.
Welcome to the forum and I am sure someone can answer the question. I was using Music Creator 4 in XP though, still on the computer and have not used it lately but still the different version like those (maybe not the newer versions of Sonar) are all about the same just not as complete a product in Music Creator than Sonar versions although lately I am using Sonar 7 and just doing audio instead of midi.
 
If the two midi tracks are different channels, then you may get repeated notes also, but then how would Music Creator know what note you wanted to keep. I think you just have to click on the note you do not want and delete it (right click if I remember right.
Left click sounds the note if not at the end or beginning of the note, and the pointer will change anyway in which direction the editing pointer works either horizontally or vertically.
