Matt suggested I start a new thread on this one...
First off - I'm using 2008.5 (265)

Sometimes (not always) if I set the bass note of the chord other than the root, it will 'blip' on playback (partially cuts out).
Most times if I simply redeclare the chord/note, it will go away..
BUT then it does the same thing in another part of the song that was working fine before... inconsistently consistent! Other times it will play the root bass note even though it's written with a different bass note....
I will play through the tune, correct all of these instances, save it, and create a wav file, and on playback, the wav file still has blips, but in different spots!!
Not a huge deal, but it should not be happening....
