Arduino-Foot-Controller

An arduino mega foot controller with 10 presets
This project may or may not swit your needings.
It does everything that many foot controllers do, but I have setup it to work with dpdt (permanent) switch.
It also will have different actions on the LED's / button state depending on how they were setup.
E.g.: If you have setup the buttons 1, 2, 3, 4 and 5 to send PC messages and 6, 7, 8, 9, 10, 11 and 12 to send CC's,
things will work somewhat like this:
You will setup the initial state of the CC buttons (from 6 to 12), according to each PC button.
If you step button 1 you may setup as follows:
Button 6 - On
Button 7 - On
Button 8 - Off
Button 9 - Off
Button 10 - Off
Button 11 - On
Button 12 - On

This way, if you step the button 6, it will send a midi OFF message.
If you step the button 8, it will send a midi ON message.

I made this foot controller to use with my Atomic Amplifire, which doesn't send/receive Sysex messages
(or at least they don't have it documented anywhere).
So for it to work as synced as possible, the button's states have to be the same as the unity's states.
E.g: If you are using the button 1 to send PC 90 and go to preset 90
and in this preset you are using button 6 to turn Boost On/Off, you must setup the button 6 to the same
state it was setup in the unit. If Boost is Off in the unity, button 6 must be off in the controller and so on.
