I just updated the OS finally and I did notice on certain presets the volumes seem lower, in some cases it’s the oscillator volume in some cases it’s the whole patch. Specifically the patch Hamonized or whatever it’s called, I didn’t check the factory slot to see a comparison but it did seem quite low. On the patch Electric Guitar the oscillator volume, even when maxed out seemed low but the samples were a healthy volume. I created some new patches and all seems well with those.
Oh and I did notice on one of my own patches the Wurlitzer seemed out of tune. I reprogramming it and it seemed okay after. Hmm.
