This is my programmable midi pedalboard.
Sends program changes through the button combination 2+3 and 5+6.
Supports double-click and long press. Have just 6 buttons but supports 4 layouts (6x4=24 buttons) switching using the vertical combinations 1+4 and 3+6.
Keeping pressed the central combination 2+5 for two seconds shows the menu to store the button states, edit the button actions, set the channel and reset the pedalboard.
Is is not synchronized, stores the button state (on/off) for each patch and sends the whole state configuration at the patch change.
