Spectravox in Bitwig (Patreon)

Moog Spectravox Overview

Type: Vocoder/Filter Bank

Filters: 10 (1 low pass, 8 band pass, 1 high pass)

Frequency Control: Fixed frequencies, adjustable globally via spectral shift knob

Key Points

Sound Quality: Unique Moog sound, difficult to replicate in software.

Hardware vs. Software: Lacks tactile experience of hardware; sound and buttons are not easily replicated in Bitwig.

Replicating Spectravox in Bitwig Studio

Filter Banks Setup:

Analyzing Filter Bank: Splits audio into bands, uses envelope followers to analyze amplitude.

Synthesizing Filter Bank: Modulates output amplitudes based on analyzed data.

Modes:

Vocoder Mode: Applies amplitude changes from analyzing part to synthesizing part.

Filter Bank Mode: Manually adjusts volumes without amplitude changes.

Oscillator and Audio Carriers:

Internal Oscillator: Use pulse wave or saw wave.

External Audio Carrier: Replace oscillator with real audio (e.g., beats or synth sounds).

Microphone Input: Use voice to trigger the envelope generator.

Practical Steps

Testing and Adjustments:

Spectral Shift: Adjusts all filter frequencies simultaneously.

Filter Volumes: Manually adjust individual filter volumes.

Oscillator Frequencies: Change oscillator frequencies to see the effect.

Switching Carriers: Experiment with different audio inputs (oscillator, beats, microphone).
