I've recently become interested in analog synthesizers and have successfully built this VCO from MFOS.
The VCO outputs a signal that varies from 0 to about 10 or 12V DC at 28mA. I want to bring this down to (roughly) line level so I can record it without blowing up all my stuff.
Using Ohm's law I figure that a 20Ω resistor should bring the voltage down to about 0.5V. Does that sound right?
I'll need to use a capacitor to filter out the DC bias of the signal (right?) How do I calculate what capacitance value I need?
Here's a link to the schematic for the main part of the oscillator. The output I want to tap (at least at first) is the sine wave output next to R49 (near the bottom right.)
