This repo contains a mod for the monome norns that will allow you to control the norns using midi cc commands.
Using this mod will let you use a controller like the Midi Fighter Twister or the OMX-27 to remotely control your norns. This is useful if your norns is placed far away and it's difficult to access the buttons and encoders.
For button CC's you should send a 127 for button on and 0 for button off. For encoder CC's you should send a 65 for CW and a 63 for CCW
The default midi channel is 10
The default cc's for the encoders are 58, 62, & 63
The default cc's for the buttons are 85, 87, & 88
You can change these in the parameter menu. Or edit the script to change the defaults.
