Hi Julian, thanks for your kind words!
I had thought of doing this in the same way as the Tech21 pedals, but I'm not the biggest fan of that interface, although it would have been easier! I have been lucky as most of the basic code structure for the menu and rotary encoder was already available to download online. Just needed some tweaking!
All of the menu navigation is done with the rotary encoder, including saving presets to the Arduino EEPROM. The first footswitch primarily deals with bypass. The second footswitch is for selecting one of the three available presets. When the pedal is in bypass mode, the preset footswitch selects the preset that will be activated by the bypass switch. When the pedal is active, the preset footswitch chooses the desired preset, and the bypass LED flashes to show that a preset change has been selected. The selected preset will only become active when the bypass switch is pressed again. I wanted to keep the number of controls to a minimum and couldn't think of another way to do it!
Ideally I would like to use 4 rotary encoders, each surrounded by a halo of LEDs for level indication, but that seemed a little excessive, and putting it in an enclosure would be virtually impossible for a DIY project!
