“Glissando ring modulation”

The patch in Fig. 3. produces some interesting
sounds. Input two VCOs set to an exact harmonic
interval (eg. a fifth or octave) into the ring modulator.
Send the pitch CV direct to the first VCO, but run the
second oscillator’s CV through the upper section of the
slew limiter (A-170) first.

Whenever the pitch CV changes, the ring modulation
causes gradual changes in the sound spectrum.

Use the upper part of the A-170 for this,
because the diode offset in the lower part wlll
put the VCO out of tune.
