[sdiy] jitter in oscillators for music purposes

The earlier Nords ran at 48k 2x oversample, though the later ones run
straight into 96k converters (i.e. Nord 2x). The control rate modules
on the Nord Modular are indeterminately dropped into 4 bins each of
which is run every 4th sample, which I'm assured can be unpredictable.
I presume the Nord Leads would have had this set up by hand.
