-FORGE allows you to send the midi data in the form of groups.
+Each input code can be either a midi event or a key code.

+#### Input groups
+
+FORGE allows you to send the midi/keyboard data in the form of groups.
 
 Each group has the following properties:
 
-* A number of layers with `MIDI_X_ACTIVE_COUNT` (default: `1`)
+* A number of layers with `GROUP_X_ACTIVE_COUNT` (default: `1`)
-* Each midi code controlling how to change the active layer with `MIDI_X_ACTIVE_Y`
+* Each midi/keyboard code controlling how to change the active layer with `GROUP_X_ACTIVE_Y`
-* A number of codes with `MIDI_X_COUNT`
+* A number of codes with `GROUP_X_COUNT`
-* Each midi code controlling the active layer with `MIDI_X_Y` (as a `vec3`: `_X` / `_Y` / `_Z`)
+* Each midi/keyboard code controlling the active layer with `GROUP_X_Y` (as a `vec3`: `_X` / `_Y` / `_Z`)
