Any patch, any amount of time from 20seconds to 2 or 3 minutes. Hint: play a chord with 4 notes and hold it DO NOT play the chord again just hold down the keys of your first chord. If you can tweek away with your free hand, I believe the unresponsiveness is provoked more so if you can tweek two knobs or more together and choose different knobs all over the virus - filter section, amp env, fx, semitone, value 1 2 and 3, just go a bit nuts, don't be to slow about it either just twist away rapidly. I can get it to happen around 80% if the time, the longest I went was about 5 minutes but it did eventually do it.
When it happens; keep the initial chord held, set osc balance to middle, filter balance to middle then rake the cutoff 1 and 2. You should hear some changes, but nothing.
I could take a video of me doing it but my canon camera just got an e18 error. Apperently fatal!
