These are some shots of the output of the Q&D VCF , one of Tim Escobedo's elegant designs.

Blue and orange LEDs were used and a variety of different resistors (1k ohm and less) were connected in series with the LEDs as suggested by Ian Fritz. This contributes to taking the sharp edges off the waveforms enabling the output signal to appear more stable and rounded.
