At the moment it is possible to create two tone change at the exact same time in EOF which lead in rocksmith to simply don't do any other tone change during the rest of the song after getting past the double tone change.

 

At least having an alert if two tone change have the exact same position to prevent this to happen would be great. I search for sometime what was the reason my tone change didn't happen as i wanted because of this.

For some reason I missed this thread. I've corrected this now.
