gumidicontroller's Introduction

guMIDIcontroller - Dependencies

AceButton - for everything to work :)
midiUSB - to send MIDI over USB
LiquidCrystal_I2C - for guLCD - to connect to hd44780 with I2C multiplexer
EEPROM - to save and restore last used program and input jack on startup .

All of these are available from Package Manager in Arduino IDE.

Features

7 program banks
Sends MIDI CC or notes over USB
Can control A/B input audio switch
Can be extended to control other features over user buttons
Keeps last used program bank on power-off
Keeps input audio switch on power-off
Turns off LCD sreen after set timeout

Known issues:

Names could be better
Should refactor HWConfig to incorporate more things or change name to ButtonConfig
UserAction, MidiValue and Action structs are mutants, because of them there are if's everywhere
Dunno how to deal with EEPROM access. For now its handled in main file.
Not all "raw" types are changed into meaningful aliases.
Control Switches (ctrlBtn2 and next in future) need to be checked upon setup also.

Take it and modify it

Feel free to leave issue on github if you have comments or feature requests although I don't plan on developing this much more.
Code is used in "production" (made one copy of device, and it work :) ).

Feel free to modify and use as defined by GNU GPL3, it would be awesome if you can give me a notice that you use this - it's always nice to know that this helped someone :)
