NanoGig Screen

A standalone, USB-powered gig screen for the Nano Cortex. It talks to the pedal over Bluetooth on its own, so there's no phone on the floor and nothing to unlock before a song.

Features

Boots straight to the gig view

About a second from power to a useful screen, with the preset names remembered from last time while it connects.

Preset, capture, IR, FX

The preset name and bank label, footswitch badges, the five FX blocks in their category colours, capture and IR with on/off state, gate and tempo.

Switch and toggle

Step through presets with the arrows by the name, hold for the full list. Tap a tile to turn a block on or off; tap the gate.

Edit on the screen

Hold an FX tile for its model and parameters. Capture and IR pages with banks, the library and previews. Rename presets on a touch keyboard.

Tuner, tempo, expression

A big tuner, a tempo view that follows tap tempo, and the expression pedal's assignments with their ranges.

Pedal settings

Every setting on Cortex Cloud's settings page, written straight to the pedal. Firmware updates over Wi-Fi.

Supported boards

NanoGig Screen runs on these off-the-shelf ESP32 touchscreens. Each gets the same interface laid out for its size.

Board guide
The pedal takes one Bluetooth connection at a time. Close Cortex Cloud and the NanoGig app before the screen connects, or use the screen's Menu → Disconnect to hand the pedal over to them.
