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
