@Jaca, is there any chance you happen to have the firmware file for the DecaBox? I also got a secondhad DecaBox, but it has the DMX Recording/Playback firmware, not the MIDI to DMX conversion firmware. I’m _also_ looking to use my LP-16 that plays backing tracks and .mid files to also control some DMX lights. I had assumed that Response-Box would have a downloads section on their website for the different firmware flavors for the DecaBox, but they don’t, and they aren’t responding to my emails. I’m guessing because I’m not _their_ customer, as I bought the unit on eBay secondhand.
