EvoFaderWing - Wiki

Author: ShawnR Contact: stagehandshawn@gmail.com OSC control of grandMA3 faders with motorized feedback, backlit faders (follows appearances), 20 encoders, and 40 standard exec buttons. Note: This Guide is a work in progress but EvoFaderWing is fully functional. I continue to work on the repo as time permits.

Bill Of Materials

Wiring Diagrams

Assembly

I have added discussions to the repo so any questions can be asked there.

Features

Same quantity of control surfaces as grandMA3 onPC Fader Wing

• 10 Motorized faders
  • Touch sensitive
  • LED backlit - follows appearances and brightens when touched
  • Self calibrated fader range and touch sensitivity
• 40 Executor keys (OSC or USB)
  • Can send keystrokes using OSC to execute actions only
  • USB allows you to apply actions (store, edit, etc.) using the hardware keys
• 20 Executor Encoders
• Web GUI

Required repositories

There are 3 repositories you will need to complete this build. This one is the main controller. The other two are:

• EvoFaderWing_keyboard_i2c
• EvoFaderWing_encoder_i2c

These run on ATmega328p MCUs and are I2C slaves for getting encoder data from 20 encoders (5 each on 4 ATmega328p's), and 1 ATmega for the keyboard matrix.

There is a Python script and a tasks.json for uploading code automatically for when the FaderWing is closed and you cannot get to the bootloader button.

Required Lua

The Lua script /lua/EvoFaderWingOSC.lua will poll executors and send updates to the FaderWing using bundled OSC messages, and the FaderWing will send OSC back to the script.

• You will need to create 2 OSC connections
  • The first will be for incoming messages and will be set to recieve.
  • The second will be from outgoing messages and will be set to send.
  • Both will need to be set to a fader range of 100

Web GUI

• Network Setup

• OSC Setup

For a complete setup add EvoCmdWing

More to come. Thank you for checking out my project!
