Dave Smith Instruments SYNTHESIZERS

Hey all, new mono desktop owner here. I love the little box a ton
already! 

I've been doing a bit of "jamming" with my Evolver running on its own,
no controller or keyboard or anything, just working the knobs. Stuff
like setting up a sequence with one osc, letting the other drone on,
doing modulation with the two digital oscs, etc. while tweaking the
delay, filter, feedback loop, and so on. 

One thing that's kind of bad, for an analog synth, is the audible
stepping from the tuning being hard-quantized on the VCO's. I'd like
to alter their coarse tuning without the hard stepping sound, or at
least find a way to minimize it. 

As far as I can tell, there's no way to do this just using the
evolver, no way to turn off the hard-quantizing. Is there a decent
workaround? What about assigning a Midi controller's knob or mod wheel
to do it? Any ideas?
