Ringmod 
Morgasmatron makes an outstanding Ring Modulator:
1. Patch an audio signal into Morgasmatron’s IN A .
2. Patch the Morgasmatron’s MIX output into your audio monitoring system.
3. Set the Morgasmatron to Parallel mode ( Series/Parallel Switch in the down position).
4. Bypass both filters by setting the DRY switch to the up position.
5. Phase invert Filter B by setting its Phase switch to the up position.
6. While sending audio into IN A , set the XFADE knob to the straight-up (noon) position. Tweak
the setting of the XFADE knob until the MIX output is as silent as possible.
Since the two filters are 180 degrees out of phase, they will cancel each other out when their
levels are balanced.
7. Route an audio signal (such as a simple sine wave) from an external oscillator into the
Morgasmatron’s XFADE CV Input , and turn up the XFADE Attenuverter .
8. Instant ring modulation!
Use this as a jumping off point for further exploration: change the pitch of the XMOD CV;
change its waveform; switch the filters out of DRY mode, and experiment with applying different
filter settings to the sum and difference frequencies. Let the sound be your guide…
