Hey there. Just got Serum and when switching presets there are large audible distortions pinning the VU's sometimes on 1 channel or both. Getting out of preset and going back in stops it or not. ??? Mac Mojave 10.14.4 2,4 ghz, I7 with 16 gb of RAM usually 6-8 gb usable. Reason 10 running Serum Native.
