TonalTrackSpacer by KILLIHU
Overview & Inspiration
Traditional track spacer plugins carve out frequency space using fixed bands or dynamic spectrums, but what if your mix collisions are fundamentally musical rather than spectral? What if the problem isn’t just frequencies, but overlapping notes?
TonalTrackSpacer by killihu approaches mix separation from a musical perspective, applying inverse EQ based on actual notes rather than arbitrary frequency bands. By intelligently controlling EQ Eight’s filters using MIDI note input and audio analysis, it creates precise tonal space where instruments compete—attenuation that follows the music, not just the spectrum.
This MaxforLive device uses eight detection filters positioned across eight octaves, automatically adjusting EQ Eight’s frequency and gain parameters in response to external audio and MIDI signals. The result is CPU-efficient, musically intelligent dynamic EQ that solves frequency masking with note-aware precision.
Features & Highlights
Musical Note-Based Processing – Unlike traditional track spacers using fixed frequency bands, TonalTrackSpacer positions filters according to musical notes and octaves, creating attenuation that follows harmonic relationships rather than arbitrary spectral divisions.
Intelligent EQ Eight Control – Automatically manipulates an EQ Eight instance, positioning each of eight filters at different octaves while dynamically adjusting frequency and gain parameters based on external audio and MIDI input.
Eight Octave Detection System – Eight internal detection filters span eight octaves, focusing frequency analysis precisely where musical content occurs, enabling efficient attenuation without unnecessary filter proliferation.
MIDI Note Control – Receive MIDI notes to automatically tune detection and EQ filters to specific pitches and octaves, ensuring attenuation targets exact musical conflicts rather than broad frequency ranges.
Dual Input Modes – Operate with MIDI input for dynamic note-following behavior, or without MIDI by manually setting a single target note—flexibility for both harmonic and static frequency management.
Manual Filter Adjustment Mode – Disable automatic control to manually position all eight detection frequencies and EQ Eight filters independently, perfect for custom tonal carving or creative effect processing.
Adjustable Detection Sensitivity – Fine-tune internal filter bandwidth for more accurate frequency detection at higher values or broader response at lower values, matching analysis precision to source material complexity.
Musical Width Parameter – Set EQ Eight filter bandwidth using musical intervals (octaves or note counts like “1 Oct” or “4N”), maintaining musical relationships rather than working in abstract Hz values.
Attack and Release Smoothing – Control how quickly EQ Eight filter gains respond to detected signals, enabling everything from transparent dynamic separation to rhythmic pumping effects.
External Signal Processing – External audio input features adjustable gain (affecting attenuation depth), dedicated low-cut and high-cut filters for focusing analysis on specific frequency ranges, plus a listen mode for monitoring the sidechain signal.
Flexible Routing Options – Select external audio and MIDI sources from any track and tap point in your project, with independent enable/disable controls for audio and MIDI inputs.
CPU Efficiency – By focusing detection filters on musically relevant frequencies determined by MIDI notes, TonalTrackSpacer uses significantly fewer resources than spectrum-scanning alternatives while achieving more musical results.
Creative EQ Eight Integration – Access EQ Eight’s full feature set including filter type modes and Scale control—invert Scale to boost target frequencies instead of cutting them, transforming the device into a note-following enhancer.
How to Use
Drop TonalTrackSpacer onto the track requiring frequency space. The device automatically links to an EQ Eight instance placed immediately to its right (if EQ Eight loads first, the link happens automatically). Use the Link button to manually establish this connection if needed.
Select your external audio source using the Audio From menus, choosing both the track and tap point (Pre Fader, Post Fader, Post FX). Enable the Signal button to activate audio detection. Adjust Gain to control how much the external signal’s level affects attenuation depth.
For MIDI control, select your MIDI source using the MIDI From menus and enable the Control button. When MIDI notes arrive, TonalTrackSpacer automatically tunes all eight detection filters and EQ Eight filters to match the note across eight octaves. The piano keyboard displays incoming notes with LED indication.
To set a static target note without MIDI input, disable the Control button and click the desired note on the piano keyboard. The device will store this note and position all filters accordingly.
Use Attack and Release to smooth how quickly EQ Eight’s filter gains respond to detected signals. Higher Attack values prevent abrupt attenuation, while faster Release allows filters to return quickly when signals stop. Adjust Sensitivity to focus detection—higher values narrow internal filter bandwidth for precise frequency targeting.
Set Width using musical intervals: “1 Oct” creates octave-wide notches, while values like “4N” (four notes) create narrower cuts. This musical approach ensures filter bandwidth maintains harmonic relationships with detected pitches.
Apply Low Cut and High Cut filters to the external audio input to focus detection on specific frequency ranges, preventing low-frequency rumble or high-frequency noise from triggering unnecessary attenuation.
Enable External Signal Listen to monitor only the sidechain input while bypassing EQ Eight, useful for diagnosing detection behavior and setting input parameters correctly.
Activate Manual mode to disable automatic filter control. The eight detection frequency knobs appear, allowing you to position internal filters manually. In this mode, EQ Eight’s filter frequencies and bandwidth become independently adjustable, enabling custom tonal sculpting or creative processing.
For creative applications, use EQ Eight’s Scale control: normal (positive) values create attenuation, but inverted (negative) values boost detected frequencies instead, transforming TonalTrackSpacer into a note-following harmonic enhancer.
Ideal For

- Ducking vocals or lead instruments around conflicting melodic elements
- Tonal separation in dense harmonic arrangements

Frequently Asked Questions
A: TonalTrackSpacer is a MaxforLive device that creates frequency space using musical note relationships rather than fixed frequency bands. It automatically controls an EQ Eight instance across eight octaves using external audio detection and MIDI note input, providing musically intelligent dynamic EQ that follows harmonic content.
A: Yes, TonalTrackSpacer is a MaxforLive device.
A: MaxforLive is a platform that integrates the visual programming environment Max with Ableton Live, allowing users to create and use custom audio, MIDI, and control devices.
A: Traditional track spacers use fixed frequency bands or continuous spectrum analysis. TonalTrackSpacer positions its eight detection filters according to musical notes and octaves, creating attenuation that follows harmonic relationships. When you send MIDI notes, all eight filters automatically tune to that note across eight octaves, providing musically precise frequency carving with lower CPU usage.
A: No, MIDI input is optional. You can disable the Control button and manually click a note on the piano keyboard to set a static target pitch. The device will store this note and position all eight detection filters accordingly. MIDI input is useful when you want the device to dynamically follow changing notes in real-time.
A: TonalTrackSpacer must be placed immediately before an EQ Eight instance. It automatically links and controls EQ Eight’s eight filters, positioning each at a different octave and dynamically adjusting their frequency and gain based on detected audio content. You can still access EQ Eight’s controls for additional adjustments like filter type modes.
A: Manual mode disables automatic MIDI and audio-based filter control, revealing eight frequency knobs for positioning detection filters independently. In this mode, EQ Eight’s filter frequencies and bandwidth also become manually adjustable, enabling custom tonal sculpting beyond the device’s automatic note-following behavior.
A: Yes! Beyond transparent mix separation, try inverting EQ Eight’s Scale control (negative values) to boost detected frequencies instead of cutting them, transforming TonalTrackSpacer into a note-following harmonic enhancer. Adjust Attack/Release for rhythmic pumping effects or use Manual mode for creative filter positioning.
