How it works

• DAW sends out MIDI
• Qlc+ receives MIDI and has mappings to a bunch of functions, matrices etc.
• 3 ESP32 DevBoard units are connected via Ethernet to the computer running Qlc+.
• Qlc+ broadcasts all Artnet universes to the network.
• ESPs filter universes according to their firmware configuration.
• ESPs use FastLED to get alight.

Firmware configuration

These values are set according to the selected firmware configuration:

Config	IP	MAC	NUM_LEDS
MODE_CIRCLE	192.168.1.24	222.173.190.239.254.237	507
MODE_ARROW	192.168.1.25	222.173.190.239.254.238	452
MODE_LASERSCISSORS	192.168.1.26	222.173.190.239.254.239	646

Libraries

Main libs involved are

• FastLED for LED control
• ArtnetEther for network communication Details see platformio.ini.

Color Codes

MIDI Mappings

Mapping MIDI notes from the track in our DAW to controls in Qlc+. These controls play animations or control single color values for our lights, which are the SnipDrop and some Asteras. (This has nothing to do with the code in this repo, just notes about our setup.)
