Dynamic DMX playback machine with MIDI & dry contact triggers.

Hot off the presses, this one.

This is a neat little controller, packed with features and potential uses.

At its core, it records DMX at 30 frames / second to an SD card. A 512 MB card provides about 180 minutes of continuous capture. Cards up to 2 GB may be used, but a 512 MB card is included.

The lesser of 128 dynamic scenes or 180 minutes of data capture may be accessed through the system menus.

Once data has been recorded, it can be used in several ways.

Using the pushbuttons and menu system, any captured scene may be played back and (optionally) looped.

Automatic playback (and looping, if desired) of a specific file may specified for when the system first powers on.

The first 8 files may be triggered via dry-contact closure. If necessary, files will loop until the contacts are re-opened.

Since a MIDI channel contains 128 discrete notes, playback of all 128 DMX files may be started or stopped using incoming MIDI note on / note off messages. The MIDI channel may be selected [1 16] using the LCD and pushbuttons. Scenes will loop if necessary.

Stored DMX scene playback may be triggered by incoming DMX data. In this mode, the incoming DMX channel value (ranging from [0 255]) is divided by two, and playback of the resulting file commences.  Setting the DMX channel to zero stops playback of the file and clears the DMX output stream.

Further, the on-board relay may be triggered by either a MIDI note on/off message or an incoming DMX channel value.

These systems will ship starting May 15 for $260. If you’d like to reserve one, send an email to ‘playback AT response-box.com’ with the subject line ‘I Need a DMX Recorder.’

System Features

  • DMX in, out & through on XLR-5 jacks.  Alternately, there’s space for terminal blocks if the jacks aren’t installed.  DMX input is optically and galvanically isolated from the rest of the system.
  • MIDI in + terminal block connections.
  • 8 sets of dry contact closure inputs, optically isolated from the rest of the system.
  • Relay output (10A 120V AC / 8A 30V DC), with NO / NC connections accessible on terminal blocks.
  • 9-12V DC input, center positive, via standard 2.1mm barrel connector.  North American orders will ship with a wall-wart type power supply.
  • 2 x 16 LCD + 3 pushbuttons for system navigation
  • 3 LEDs for system feedback

As always, if you need something similar but the existing firmware doesn’t seem to cover it, just let us know.  The neat thing about software is that it can always be changed.

  • SD card socket
  • Firmware updates through the SD card are also possible
  • Board measures 4.25″ x 4.25″

    When I stop to consider that six years have passed since we designed and shipped our first video projector shutter, I shake my head in amazement.  What a tremendous journey it’s been.  If you’re a former customer who has returned to the site to take a look, please accept our gratitude for the chance we’ve had to serve you.

    It’s time to update the website.

    We’re also super excited to announce the release of our DecaBox Protocol converter. While we’ve actually been shipping them for a few months, it’s taken far, far too long to get proper pictures other information posted here on the site.  Take a look – if you need some crazy combination of DMX, RS-232, MIDI or IR communication implemented, there’s a really, really good chance we can help you out.

    Thanks for visiting, and feel free to poke around.  If you can’t find what you’re looking for, we’d be happy to chat by phone or email.  My direct line is (801) 949-8294, and I’m available from 9:00 – 5:00 Mountain Standard Time on weekdays.

    Note also that if you enter your name and email address in the top right corner of this page, you’ll receive automatic email updates when content here changes.  Plus, from time to time we add gently used / refurbished gear to the bargain bucket. If you’re on that email list, you’ll have 4-6 hours advance notice of these deals, before they go live to the world.

    Quick story: a couple weeks ago, we had a passel of refurbished projector shutters (ex rental stock) available, and at prices which made our accountants weep, wail & gnash their teeth.   They were snatched up by folks on the email list within just a couple minutes.  It pays to join the Insiders’ Club!

    Warmest regards,

    John Chapman & the Engineering Solutions team
