Editor

Build your rig in the grid, then use the panel below it to shape the selected module. The main controls stay visible while you browse sounds, so you can compare tones without losing your place.

Find your way around

Area	What you can do
Header	Switch scenes, load or save rigs, open Modulation, the tuner, and Settings.
Grid	Arrange modules across Pre, lanes A/B, and Post. See Grid & routing.
Module editor	Adjust the selected module, switch its mode, and view its response.
IN / OUT	Set the level entering and leaving the whole rig.
Macros	Adjust four assignable controls below IN. Double-click a label to name it; names and values are saved with the rig.
A/B	Balance the two parallel lanes. Routing opens their level, timing, and split controls.

Settings, Tuner and Modulation have icons beside their names. The page-with-plus and disk icons beside the preset arrows are New and Save; hover over them for help. A divider and subtly lighter background mark the parameter area below the grid, including when auditioning modules in the browser.

Visualizations use the same black as the grid, with matching space above, below and to the right of the module display.

Build and arrange a rig

Each grid card is one slot. Click + Add module or a module's name to choose a module in the library browser, which lets you audition before you commit. Click the card's header to select it for editing, and use its switch to bypass it.

Drag cards to move, swap or copy modules, or right-click a card for Clear, Copy, Move and Swap; the mouse and keyboard table lists the drag modifiers. Controls and bypass travel with the module, while host automation stays with the slot. Moving modules never copies or deletes files on disk.

Shape a module

Every module editor uses the same layout:

• Top row: slot ID, category badges and the enable/bypass circle, then the module name. Browser and previous/next align on the right. The circle controls the same automatable Enabled parameter as the grid node.
• Options: tempo sync and sound-specific choices such as Style, Mode, Quality or Heads, on the right of the description row. Click a two-choice option to toggle it; longer lists open a menu.
• Knobs: up to four per row, filled from the left. Output comes before Mix. All eight positions are available for sound controls.
• Display: a visual guide to the module's response or your playing, with that module's input, output and gain in its footer.

Drag a knob or click its value to type a number; double-click restores its starting value, and right-click assigns modulation. Every knob and Enabled can be automated by your DAW; other header options are saved with the rig but cannot be automated.

Previous/next stays within the current effect category or capture/IR folder. Adding a module gives you useful electric-guitar starting settings, with acoustic and bass suggestions.

Displays and meters

Displays help answer practical questions: Is the compressor working? How dark are the repeats? Where is the EQ cutting? Some show live audio; others sketch the current settings. Their labels identify which is which.

Use the level meters in the display footer to compare tones at similar volume. They read the same scale as the slot meters, -60 to +6 dBFS:

• Gain near 0 dB means the module adds little overall level—useful for a fair bypass comparison.
• The bar is RMS over the last 0.4 seconds; the tick is the held peak. The two numbers read RMS, then peak, in dB.
• Red above 0 dBFS warns of a hot level. Between modules this is headroom information; at OUT, it is the level sent to your DAW.

Turn all displays on or off in Settings > Visualizations. This changes only the display, never the sound or saved settings. The module guide explains each module's display.

Settings

Settings in the header manages your capture, IR and preset folders (see library folders) and a few preferences:

• Visualizations turns all module displays on or off.
• Main macros shows or hides the four knobs below IN. They are shown by default; unassigned macros are dimmed. Hiding them preserves their values, names and assignments.
• Preset switch chooses how rigs change while you play; see rig presets.
• Startup rescan rescans your folders whenever NAM Grid starts.
• Settings folder opens the folder that stores these choices; see where settings are stored.
• Links to this documentation, the source code and the issue tracker.
