Here’s a fun new firmware build that’s been kicking around the shop for a while.

For several years, our standard DecaBox MIDI to DMX converter has been a huge hit.  It’s been used all over the world by artists, musicians and lighting designers with great success.

The gist of that system is that discrete MIDI notes are mapped on a 1:1 basis to DMX channels.  The note velocity (or the intensity with which the note is presssed) is equal to the DMX channel value.  Elsewhere on this site are quite a few videos of that system in action.

However, it was suggested that we come up with a way to trigger more intricate DMX scenes through a simple MIDI interface.  There’s a practical limit to how much MIDI information can be sent down a wire at one time, and it can be difficult, if not impossible, to generate complicated color fades over many fixtures at the same time using only MIDI note data.

For a long time we’ve been able to record incoming DMX to memory cards, then play it back on command.  So it didn’t take too much work to add MIDI triggering.

So, this new firmware requires an external source of DMX.  It can be a lighting console, a program on a PC, or anything else which generates a valid DMX-512 signal.

The DecaBox captures incoming DMX scenes, saves them to memory, and then assigns them to a single MIDI note for playback.

The signal path looks like this (click to enlarge):
