In this video we explore how to use Spectravox to process guitar and look at recreating some of the Moogerfooger effects pedals with it.

We begin by using the Program section and its preamplifier to bring a guitar signal up to Eurorack levels for processing, and then connect the Program section output to the filter bank’s Carrier input. Here is how to recreate or simulate some of the Moogerfoogers:

MF-103 Phaser – use the filter bank as a comb filter and modulate it with the LFO for resonant phaser tones.
MF-101 Lowpass Filter – use only filter 1 (lowpass filter) and the Program Envelope Follower to get enveloped filtering. Switch to one of the bandpass filters for auto-wah effects.
MF-102 Ring Modulator – modulate the VCA CV with the LFO for tremolo effects and push the LFO to audio-rate for ring modulator-esque amplitude modulation. Explore amplitude modulation of each filter band respectively via their CV inputs
MF-105 MuRF – send an external sequence (from DFAM, Grandmother, or any sequencer) to the Shift input for sequenced resonant filter bank movement. Modulate each filter band individually with independent envelopes for even more MuRF-like behavior.

Spectravox is an open-ended signal processor, so use these as starting points and explore the myriad of unclassifiable effects Spectravox is capable of.
