[sdiy] Adding a second VCO with level control

[Richard Atkinson]

Put a resistor between the output (wiper) of the pot and the point in the 
xoxbox circuit you're connecting it to.

If there is any series resistance between the output of the VCO and the 
input of the VCF, one approach would be to match this resistance, or find an 
appropriate value that gives equal amplitude to both VCOs at the maximum 
setting of the pot.
