1. Spectravox | Sculptable Synthesizer Voice

"In this video we explore how to use Spectravox as a standalone synthesizer voice.

We begin by configuring Spectravox for keyboard control – patching the Keyboard CV output of Grandmother to the 1V/OCT input on Spectravox and the Keyboard Gate output of Grandmother to the Trigger input on Spectravox. Playing Spectravox this way gives us a unique analog synthesizer voice where the ten filters and Spectral Shift controls allow us to sculpt the sound of Spectravox’s Voltage Controlled Oscillator. We look at using these controls alongside the LFO for both traditional lowpass and hipass filtering as well as unique notch filtering, comb filtering, and phasing effects. Lastly, we look at using the LFO and the VCA input to create tremolo effects."

Spectravox | Filter Pings and Analog Physical Modeling

In this video we explore how to ping the filters of Spectravox to turn it into an analog physical modeling instrument and create percussive wooden sounds like marimbas or xylophones. By replacing the carrier input to Spectravox’s filter bank with a gate or envelope instead of audio and turning the resonance of the filter up, we can ping all ten filters and mix their levels for creating struck percussion sounds. In this video we first turn the VCA mode ON and then patch the Gate output of Grandmother to the Trigger input of Spectravox to use Grandmother to trigger Spectravox’s envelope generator. Patching the EG output to the Program input gives us level control of the envelope, and finally patching the Program output to the Carrier input inserts our decay-only envelope directly into the audio input of the filter bank. Later, we connect the Keyboard CV output of Grandmother to the Shift CV input on Spectravox to move all ten filters for melodic control of the filter bank.

2. Spectravox | Recreating Moogerfooger Effects for Guitar

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.

3. Spectravox | Emulating a Vintage Drum Machine

Embark on an exploration of Spectravox's capabilities as we delve into the intricate art of crafting vintage drum machine sounds with a contemporary flair. 🎛️💥 Join us in a meticulous fusion of Spectravox and rhythmic sequencers, aimed at resurrecting the beloved beats reminiscent of the 1970s and the nostalgic rhythms of vintage organs.

Unveil the methodology behind sculpting the quintessential drum machine foundation through the mastery of Spectravox's Carrier section. Our comprehensive tutorial will meticulously guide you through the synchronization of rhythmic sequences sourced from esteemed trigger sequencers such as ALM’s Pamela’s New Workout. Witness the transformation of Spectravox's ten bands into a symphony of dynamic kick drums, crisply resonant snares, and timeless wood block accents. Additionally, unlock the intricate craftsmanship involved in crafting hi-hats by toggling the Bands 9 & 10 switch to Hiss mode.

However, our journey merely scratches the surface of Spectravox's boundless potential. Delve into the realm of nuanced control with Spectravox's intuitive panel controls, where each knob adjustment opens doors to a myriad of sonic possibilities. For those craving to push the boundaries of sonic innovation, we offer insights into seamlessly integrating external control voltages, thus offering a gateway to unparalleled rhythmic experiences.
