Two Knobs
TK Dynamic EQ
One dynamic band, reduced to where and how much. Intensity widens the band as it deepens it, so more really is more. Cut a resonance that only shows on loud notes, or lift something that vanishes in the quiet.
AU · VST3 · Standalone - not Pro Tools (no AAX). Formats and requirements.

Every update included
One price, and it is yours for good: every future update to what you buy is included at no extra cost. There is no subscription and no upgrade fee.
A single-band dynamic EQ reduced to where and how much. The intensity knob moves threshold, range and bandwidth together, so pushing it means more action in every sense - the band reacts sooner, moves further, and covers more ground. A toggle picks the direction: cut dips the band when its own energy pokes out, prick lifts it while it is weak and backs off once it is strong.

what's in it
Every control, and what it's for.
Nothing here talks to the Analyser, or to any other plugin. Two Knobs holds no shared state and needs nothing else installed - what you see is the whole plugin.
The two knobs
Threshold, range and bandwidth, together. Pushing it means more action in every sense: the band starts reacting sooner, moves further when it does, and widens as it goes. A fixed narrow band would cap how much of the signal the move can reach, so sweeping the width is what makes this knob mean more action rather than just a deeper notch. At zero the plugin is inert.
Sweeps the full band continuously, 30 Hz to 18 kHz. There is no stepped selector.
The toggle and the button
cut is downward - the band dips when its own energy pokes out. Use it for a resonance that only shows up on loud notes, a boxy tom, a harsh 3 kHz that only bites on the belted lines. prick is upward - the band lifts while it is weak and backs off once it is already strong. Use it to bring out something that disappears in the quiet passages without making the loud ones brighter.
Widens the band further, on top of whatever width intensity has already chosen. The intensity-driven width is right for one resonance and too narrow when the problem is a whole region rather than a single spot - a low-mid smear rather than one ringing note. Same idea, and the same name, as the de-esser button.

What to reach for it on
A resonant acoustic guitar, a snare with one ringing note, a boxy tom, a vocal that loses its air when the singer backs off (prick, up top).
Shared across the series
The same on all six, so learning one teaches you the set.
Input is level-matched to output continuously, so turning the big knob up never simply makes things louder - you hear the effect, not the volume. The compensating readout under the little knob shows what it is doing right now: negative means the plugin made things louder and the compensation is pulling back. It takes about a second to settle after a big move, deliberately - a compensator that reacts instantly is a compressor. TK Compressor is the one exception: its level rises with squeeze (see its own section).
Drag up and down to adjust. Hold shift while dragging for fine adjustment. Double-click a knob to return it to its default. You can also double-click a value readout and type a number.
A small live curve under the little knob showing what the plugin is currently doing to the signal - the transfer curve, the filter shape or the gate contour, depending on the plugin. It follows both knobs and the toggle.
Drag any edge. The aspect ratio is locked, the range is 60 %-200 %, and the size is remembered with the session. Everything stays readable at the bottom of that range.
No preset browser, no meter, no gain-reduction display, no A/B, no settings gear. Nothing to configure and nothing shared with any other plugin - these hold no cross-plugin state and behave identically with none of the rest of the suite installed.
quick start
Four steps to a sound.
- Sweep frequency to the problem - it is continuous, with no stepped selector.
- Turn intensity up until the band is doing the amount of work you want. At zero the plugin is inert.
- Pick a direction: cut for a resonance that only shows on loud notes, prick for something that vanishes in the quiet passages.
- If the problem is a whole region rather than a single note, turn girth on to widen the band.
Not currently suitable for Pro Tools
These are AU and VST3 plugins. Pro Tools only loads AAX, which these aren't built as - so none of the suite will appear in it. Please check your DAW before you buy - once you download, the sale is final.

Where it's confirmed to work
Honest version: this is a one-person operation, so it has been properly tested in the DAWs below and not yet in the others. Not tested yet means exactly that - not that it fails.
| DAW | System | Plugins load |
|---|---|---|
| Logic Pro | macOS | Yes |
| GarageBand Confirmed with the six Two Knobs plugins on macOS. The rest of the range has not been tested there yet, and brain sharing has not been checked in it at all. | macOS | Yes |
| Ableton Live Confirmed loading on both macOS and Windows. The sharing side is still to be checked. | Mac/Win | Yes |
| Cubase / Nuendo Confirmed loading on both macOS and Windows. The sharing side is still to be checked. | Mac/Win | Yes |
| Studio One Confirmed on Windows (VST3). The sharing side is still to be checked. | Mac/Win | Yes |
| Reaper Confirmed on Intel Mac - both AU and VST3, and the plugins share with each other. Not yet tested on Windows. | Mac/Win | Yes |
| FL Studio | Mac/Win | Not tested yet |
| Bitwig Studio Confirmed loading on both macOS and Windows. Bitwig keeps plugins apart from each other by default, so the sharing side needs checking separately. | Mac/Win | Yes |
| Digital Performer | Mac/Win | Not tested yet |
| Pro Tools Pro Tools only loads AAX plugins. These are AU and VST3. | Mac/Win | No |
| System | Confirmed | |
|---|---|---|
| macOS on Intel | Yes | Confirmed working from 10.15 Catalina upwards. |
| macOS on Apple Silicon | Yes | Confirmed on an M4 Mac in Logic Pro. The installers are universal binaries, so they run natively - no Rosetta needed. |
| Windows 10 / 11 | Yes | VST3 only - there is no AU on Windows. Confirmed in Studio One, Ableton Live, Cubase and Bitwig. |
There is no second column here on purpose. This plugin passes nothing to any other plugin and holds no shared state, so a host that keeps plugins in separate processes costs it nothing - if it loads, it works. Tell me what you find in a DAW that isn't listed and this gets updated.
