Discovered a neat trick today with the omni filter.  Run a cv into 
it,  set it to low pass.  Run a voltage into the FC2 and adjust to 
invert it so you can lower the frequency of the filter way below 
minimum.  This will give you noticeable slew times.  Otherwise the 
frequency of the filter is too high to have a noticeable slew. Run the 
output to the cv in on something like your oscillator.   The filter 
will slew between changes on the cv in.   

This allows you to have a voltage controlled Slew in the wiard 300 
system.   You can also do interesting cv filtering on lfos etc with 
this patch.

I often use the VCA circuit on the VCO of Waveform City as slews -
there is a jumper on the pc board that switches the vca to a slew,
allowing the output to track the voltage at the gate input, with the
attack and decay controls adjusting the positive and negative sides of
the slew...

Of course you meant the little envelope generator inside the Classic VCO and
not the VCA. The Classic VCO has three seperate modules in the one box,
VCO, VCA and AR envelope/envelope follower. 

You can also feed audio into the "Gate" input and the envelope output will follow the 
positive peaks at the rate set by the Attack and Release knobs.

Grant, of course, yes - right.  senior moment.... 

(And to think, we used to pay for feeling like this!)
