I am using Sonar 4 (with the 4.01 patch) and when sequencing from my keyboard, I sometimes get multiple overlapping notes. I have to manually delete the duplicates when I catch it. This is obviously eating up my polyphony and causes poor phasing in the samples. What is strange to me is that sometimes I get one note without any overlaps, but the next note might have two notes and sometimes I've seen three overlapped notes. Seems a little strange, right?
My "Local" setting is off on the keyboard so that is not the problem. Any ideas of how to fix this problem?
