MOTM

One thing I like to do (which is kind of related) is to patch noise (or LF 
random) to a VC lag processor to the SH to the CV input of a VCO. With 
careful adjustment of the VC and other controls one can get the pitch to roam 
the whole 10v (ten octave) range, but moving by very small steps thereby 
taking a long time to get there -- actually, I tend to use patches like this 
more often for things other than VCOs.

I guess that patch is pretty obvious, and has nothing to do with oscillator 
drift; something which seems less novel when one has to tweak the tuning of 
the VCOs of a 2600 every three hours of use (and those sliders make it even 
more fun).
