No. I am looking for something that will yield a steady result and I
don't mind which of the two. That is the behaviour found in such
scaling/quantising features on the hardware I know about. Think Novation
Launchkey Mk3, Arturia MiniBrute 2S. I haven't worked with any quantiser
modules in the eurorack world, that support scales, but I think they
also use a static mechanism.

Best wishes and thanks,
