circuit, so that we can dial in a CV o ff set value that gets summed together with the
external CV input – in case you’d like to have your VCA open to varying degrees by
default. Because 10 V is the expected maximum CV value, we’ll also place a 20k resistor
between our potentiometer and the positive rail. Ensuring that our o
ff set will max out at
precisely those 10 V.
And with that, our VCA is done. Plug in your headphones, an oscillator and an LFO or
envelope and see what happens! If you now want to make your creation permanent, dig
out the panel and PCB from the kit, heat up your soldering iron and get to building. You
can find more information on how to populate the board & how to solder in the enclosed
appendices.
