Any knob in Outboard-EQ can be controlled from a MIDI controller. Right-click, learn the next CC, done. Bindings persist with the project.
Walkthrough
1. Right-click the knob you want to control
A context menu appears. Pick MIDI Learn.
2. Move your controller
The next incoming MIDI CC message gets bound to that knob. The menu closes and a small dot appears on the knob to confirm the binding.
3. Move the controller again
The knob follows. The full controller range (0–127) maps to the knob's full parameter range, scaled and skewed exactly like a UI drag.
One slot per parameter
Outboard-EQ uses a simple one-CC-per-knob model. Re-learning a knob replaces the previous binding. You can't bind two CCs to the same knob (use your DAW's MIDI mapping if you need that), and you can't bind one CC to multiple knobs (use your DAW's MIDI clone/duplicate for that).
This covers 95 % of use cases — assign one fader to Output Trim, four knobs to your top four bands' gain, and you have a one-page mastering control surface.
Managing bindings
The MIDI pill in the footer opens the bindings list:
- Each row shows the bound knob, the CC number, and the controller channel.
- Unbind removes a single binding.
- Unbind All clears every binding.
The pill itself glows when at least one binding is active — handy for confirming your controller is actually connected and recognized.
Persistence
Bindings are stored in an APVTS-adjacent ValueTree node as JSON, so they save with the project and reload exactly. They are not part of the preset — loading a preset doesn't touch your MIDI map.
Tips
- The smallest useful binding: bind Output Trim to a single fader. That alone makes A/B-ing a master against a reference much easier than the mouse.
- For per-band gain mapping, bind your top 4 controller knobs to Band 1/2/3/4 Gain. The other four bands are usually less hands-on during mixing.
- A MIDI binding doesn't change the knob's preset behaviour — loading a preset still writes the knob's preset value, and the next MIDI CC will then override it. So if your controller drifts, send a CC to "lock in" the current setting.

Macros
> Macros are one-click moves that touch multiple bands at once — useful when you want a common move (like "cut the low end and the low-mid mud") without spending five clicks on it.
