A visualizer which sends MIDI commands. These MIDI commands can be fed into a lighting controller to then control fancy event lighting equipment.
Events are sent as NOTE_ON/NOTE_OFF messages. The following notes are mapped:
| MIDI Note | Meaning |
|---|---|
| 50 <= n < 60 | ON/OFF for the 10 frequency channels. The 4 highest channels are ON, rest OFF. I map this to 10 non-overlapping light scenes. |
| 66 | ON when a beat hits, OFF 100ms later unless a further beat immediately follows. I like to trigger strobe lights on this. |
| 70 | Volume as note velocity. |
