tables, diagrams and fixes. built to be opened mid-session with a guitar still on, not read front to back.
the hardware
- controls and footswitchesinteractiveone knob, one button, a touchscreen and 11 footswitches. click anything on the panel to see what it does.
- inputs and outputsinteractiveevery jack is on the rear panel, and there is nothing on either side. click any jack to see what it does and what to watch for.
- Cortex Control, plugins and Wi-Fitwo reasons to own this modeler over a Nano Cortex: a desktop editor, and plugins that run on the hardware.
- specificationsevery number, with the source attached. where a bare figure needs context, the line says so: the four outputs are two pairs, and every IR is converted on upload.
sound
- the Grid and the DSP budgetonly here32 slots, four rows, two parallel paths. the processing limits apply to the row pairs.
- gain stagingonly herefive stages, in order. 0 dB is the default and “just below clipping” is the check.
- amp and capture decoderonly hereevery factory amp and capture name, decoded to the real gear. “watt D103” is a Hiwatt DR103 and “CA John’s 2C” is a JP-2C.
- tone recipesinteractivewhich amp to load and the three or four moves that matter. every amp is named as it appears on the modeler, so you can type it straight into the device list.
- making capturesonly herethe Quad Cortex makes captures, and the Nano Cortex only loads them. INST LEVEL drives the device you capture. IN LEVEL sets the capture itself.
using it
- questions and answerscommon questions, answered in a sentence or two. every answer links to the full story.
- modes, scenes and setlistsa preset is a rig and a scene is a snapshot of that rig. the mode sets which of the two your feet switch between. if your sound changed when you pressed a switch, check the mode.
- rig setupinteractivepick what you're plugging into. you get the cabling, the cab block state, and what to check.
- MIDIwhat a controller can reach, and the setting that stops a repeated Program Change causing a dropout.
- troubleshootingonly herefind the fix by what you notice: no sound, a block that will not load, a quiet output. each entry names the cause.
- CorOS release historycheck here whether a missing feature is a bug or old firmware. several things this guide describes do not exist on older releases.
