PedalSwitcher is aimed at building a relay switcher as used by many guitarists
and bassists using many effect pedals.

With the current version it has following features :
- Midi In/out/through
- LCD display
- 8 relays either switched or momentary 
- 4 menu buttons, 8 relay butttons with LED indicator
- 100 user presets
- 4 programmable quick access buttons (recall preset) with LED indicator
- grouping (radio mode) of relay buttons

MIDI CONTROL :
 PC00 : all relays off
 PC01…100 : recall preset 1..99
 PC101…108 : toggle relay 1…8
 PC109…110 : UP/DOWN preset

When a MIDI Program Change is received, the app automatically switches to the
new preset, without saving the current preset.
