    Just got a new unit, and it looks to be running software version 1.5. I can see in the various documentation that clicking on the “Centipede 416” is supposed to show/hide the sequencer interface but it doesn’t do anything. Rooting around in the source code I can see that there are no onclick events registered for that element, and I was able to find a sequencer.js that sure looks like an interpreter for the sequencer language but it doesn’t seem to be referenced by anything. I’m not a web app expert so maybe there’s something I overlooked, but it sure looks like the sequencer is disabled.

    Is there something I can do to get it back, or is it deprecated or something?

    I think you are reading some old documentation. Unfortunately the docs are not updated as often as they should be. In any case, prior to version 1.50, the sequencer was implemented in JavaScript, and so the sequencer engine ran inside the browser. This created many limitations, for example, if the browser disconnected for any reason, the sequence would stop running. Also, only one person could control and watch a session while it was running.

    So the BIG update in version 1.50 (I call it that since it took more than a year to create and debug) was to delete the JavaScript sequencer and substitute a completely rewritten version that runs inside the 416 itself. You will find a link to the new sequencer on the Centipede’s index page.

    The current sequencer guide was written by one of our customers, and while an excellent document, it needs updating. It was written based on the JavaScript version of the sequencer.

    I see, thanks! It looks like the interface you’re talking about is behind the Sessions page, and I can see the new sequencer code in the SocketServer.

    I totally understand the joys of keeping documentation up to date.

    Yes, Sessions are created to “run” sequences. This expands the functionality of sequences way beyond what was originally available. For example, you can be running multiple sessions at the same time, and a session will continue to run even if you stop watching it. Also more than one person can control or watch a session at the same time. Also buttons are now available to change a sequence’s functionality while it is running.
