[Piano Roll View] Is there any easy way to find duplicate midi notes other than running CAL scripts? Or, may be tell Sonar not to generate duplicate notes through some kind of settings?
 
I play my Fishman Triple Play equipped guitar for midi works, which lot of the times generate duplicate notes and some unwanted to low velocity notes (that's another story).. but i am still happy with my midi guitar since it lets me create a complete song different instruments. 

Yes - open up Staff View.
 
Any duplicated notes will be visible attached to both sides of the stalk
 
Select one of them and delete it.
 
Note: if at this point Sonar deletes BOTH copies of the note, just hit ctrl + z and just ONE will reappear
