Hello,

I'm a bit confused.  Don't we have everything we need to do this 
already?  And with fewer and fewer and fewer modules:

For the higher limit: patch the Voltage you want to limit into a VC 
Switch A-150 and a comparator A-167.  When the voltage exceeds the 
limit the comparator outputs a gate that can be used to shift the VC 
Switch to an unused input.   If you duplicate this but use the inverted 
input of the A-167 you can derive a gate for the lower limit.  Add a 
linear mixer A-138a for the gates and you're good to go.
Or
Put the voltage you wish to limit into the comparators and an A-130.
Forget the switch and the mixer.  Invert the gates and use them for the 
control voltages of an A-130 to turn off the limited voltage when it 
exceeds the desired range.
But
Couldn't you cut the number of modules nearly in half by deciding that 
your lower limit will be 0 volts?  You could  always add an offset 
later in the chain or reset your VCO or VCF starting points.
Or
You will be using a varying voltage from somewhere.  Presumably the 
device will have limits.  Attenuate or amplify the signal until it 
stays neatly in the range you wish.  Offset can be added before or 
after.
Or
The A-118 has a Level pot.
Or
How about the CGS Modulo Magic?   http://www.cgs.synth.net/

Or,
Have I completely missed the point???
