In two places, filters were using uninitialized memory at creation. In some cases, for some values, in some instances, this would create a large "pop" as the filter went unstable with crazy coefficients or history values. In my headless simulator, without these initialization changes we get a click and pop within the first 100 instances. With them there is no unstable run within 20,000 instances. In theory this Closes surge-synthesizer#790 Closes surge-synthesizer#753 Closes surge-synthesizer#699 Closes surge-synthesizer#698 Closes surge-synthesizer#662 Closes surge-synthesizer#660

A loud click , plop , dc offset ... appears over the right channel .
Mostly happens when playing some notes in fast succession , difficult to replicate the bug
