Given that resolution is so important I wonder if dithering a OSC is likely to improve the resulting resolution. It has part of the movement property of Drizzle - maybe it would work to enhance resolution?
In that way the benefits of mono over OSC may be reduced?
Or am I dreaming!
There is an excellent discussion here
