I just updated from 5.08 to 6.01 and had a problem concerning the pitch block. Immediately after updating to 6.01 the modifier for the pitch block had somehow been assigned to the envelope follower on the input gain knob. None of the pitch effects channels A,B,C, or D worked correctly because of it. The input gain knob was moving on it's own from 0 to 15. This was on my main template that has never had an envelope follower assigned to the pitch blocks.
After discovering what the problem was I went in and unassigned it and the pitch blocks worked correctly. Then I copy and pasted the fixed pitch block my first 40 presets. Everything seems to be fine now.
