The old behavior was to increase oversampling factor on the quality instruction, but this increased oversampling both for sampled data and synth data. For sampled data it is not strictly necessary to have oversampling greater of 1 if ww is high enough and if the sample are professional grade and not shifted too much.
Moreover the oversampling (for synth data only… for sampled data a fully fledged windowed sinc is employed) was performed with an inefficient moving average (1,1,1…1) that has a poor side band rejection.

With power oversampling you can leave sampled data oversampling to 1 or low and have up to 100x and 200x oversampling. Moreover the averaging is performed with a windowed sinc with the same parameters of the sampled one: you can resample your synth oscillator with a Kaiser window if you want, instead of the moving average, that can have way more sideband rejection of 30Db (that is about the sideband rejection of the moving average) and much flatter response in the useful range.

I tried 14x with Kaiser window (the default) on the SuperSaw and a square wave and it was virtually artifact free up to C8 (and probabily over)…

EDIT: released the v 187 with full independent oversampling setting.
