SMR

4ms

Process audio and control up to 6 VCOs with the 4ms Spectral Multiband Resonator, an innovative resonant filter module in Eurorack format. The module can process audio like a classic filter bank, ring like a marimba when struck, vocode, remix tracks, harmonize, output spectral data, quantize audio to scales, and much more.A striking ring of colored lights displays the frequency of each filter, as well as the levels and current scale selection. The SMR can also control up to six external VCOs with 1V/oct CV for sequences, chords, and melodies. The Spectral Multiband Resonator module ships with a ribbon power cable and mounting screws.Spectral Multiband Resonator Overview At a glance, the SMR works like a normal six-band graphic EQ: six frequency bandpass filters are mixed together using sliders. Resonance/Q is variable, which changes the ringy-ness or width of the bands.The frequency of each channel is treated like a note in a scale, and the six bands form a chord. Spin the Rotate knob and the notes circle around the scale, rotating back to the bottom once they've reached the top. Adjust Spread and the distance (interval) between each note changes. Triggers for up/down motion, CV inputs for sequencing and scale selection allow for flexible control with external modules. Morph, which automatically crossfades between frequencies, together with variable Slew allows rhythmic clocks to drive the SMR as a variable-speed evolving resonant filter.At maximum Resonance/Q, the SMR can be struck like a gong or marimba by inputting clocks or triggers. The frequency of each channel is quantized to a scale: beautiful chords, ethereal tones and eerie ambience flows easily. With lower resonance, the SMR can pull out particular frequency bands, and sweep these across the spectrum.Two 1V/octave Frequency jacks allow for tracking even and/or odd bands and creating floating melodies over evolving chord bases, or complex percussive membrane sounds.Save your settings into one of six storage banks and recall on the fly. On startup, the SMR instantly jumps to the last saved settings. The color scheme of the lights can be adjusted, so if you prefer all white lights on your modular, you can have that (or all red, or rainbows, pastels, etc.)Basic Functionality Six filter channels, selected from twenty active filters displayed on the light ringVariable Q (Resonance) ranges from classic band-pass to ultraresonant ringingRing of 20 full-color lights displays the filter frequenciesFilter frequencies move about the scale using Rotation and SpreadRotation spins the frequencies around the scaleSpread controls the gap between neighboring bandsMorph creates a variable-speed crossfade when the filter frequencies changeLock buttons prevent each channel from changing in frequency (resonance can also be locked)Freq Nudge knobs for creating detuning effects or honing in on an exact frequencyFrequency CV input (1V/octave) for even and odd bands (flip switch selects single or multiple channel control)Stereo ins and outs stagger the bands into evens/odds for an immersive stereo fieldSpectral content outputs for each channel (Env Out) allow for vocoding (spectral transfer)Fast or Slow tracking speeds for Envelope CV outputs, or selectable Trigger output mode is useful for extracting a beat from musicSliders and CV jacks control each filter's levelSlew switch applies slew-limiting to the CV level jacks, which prevents clicking from clocks or triggersEach bank has 11 scales of 20 frequencies/notes eachUser-programmable scales (select octave, chromatic note, and microtonal adjustments for each note in the scale)Scale banks for Western, Indian, Chromatic, Microtonal, Equal tempered, Just intonation tuningsRotation/Spread moves about an entire bank, or can be limited to a single scaleWhite noise is normalized to the inputs, so the SMR can be used without an external signalAdvanced Functionality Program your own scale.
