The Spectral Multiband Resonator is a seriously unique tool for sound design. It’s not a simple filter; it’s a resonant landscape generator perfect for experimental electronic music, ambient soundscapes, and anyone wanting to push the boundaries of modular synthesis. Be prepared to dig in – it's rewarding, but takes some effort to truly master.

Product Description

  • 4ms Spectral Multiband Resonator
  • Multiband Resonator
  • Tunable 6-channel bandpass filter and resonator
  • The frequency of each filter / resonator is quantisable to one of 11 tone scales and/or follows the pitch CV
  • Level fader with CV input and lock button per channel
  • Envelope follower output per channel
  • Two pitch inputs (1V/oct.) for even and odd channels
  • each with switchable locking function
  • Resonance control with CV input
  • Rotate encoder (with CV and trigger inputs) transposes all bands within the defined tone scale
  • Morph and spread control with CV input
  • Scale CV input
  • Stereo input and output
  • Power consumption: 110mA (+12V) / 28mA (-12V)
  • Width: 26 U
  • Depth: 24 mm
PROS
  • • Exceptional tonal sculpting with six independently tunable bands.
  • • The scale quantization offers surprisingly musical and predictable results.
  • • Envelope follower per channel unlocks unique rhythmic and textural possibilities.
  • • Robust build quality; 4ms modules are known for their reliability.
CONS
  • • The 26U width demands significant space in a modular setup.
  • • Steep learning curve; mastering all controls requires dedication.
  • • Limited flexibility for truly arbitrary filter frequencies.

Frequently Asked Questions

The scale quantization creates a more harmonic and controlled resonance, avoiding harsh or dissonant results when sweeping frequencies. It's great for creating evolving textures without the risk of unpleasant artifacts.
While it *can* be used that way, its strength lies in the resonant bandpass filtering. It’s not ideal if you’re primarily seeking a classic low-pass or high-pass filter sound.
The rotate encoder allows for quick transposition of all bands within the selected scale, creating sweeping, synchronized resonant effects with a single control, which is incredibly useful for rhythmic or melodic elements.
