Before you start

Cohort isn't a single app or platform. It's a flexible and modular toolkit. This is useful because you can use for many kinds of experiences, but the downside is obvious: it's hard to know where to start!

This page will walk you through a quick demo of the simplest possible Cohort usage: using our admin website to cue a single sound on an audience-facing website.

If you decide to use Cohort for a project, some next steps might be:

  • building a website for your audience, or customizing our example, to cue your own audio files
  • customizing our iOS and Android app template (built in Unity), to access more advanced features like video cues and push notifications
  • firing your cues from QLab or Isadora instead of our admin site, to better integrate with the rest of your production
  • running Cohort Server on a show computer instead of on a server

The Downloads page has links to all our templates, applications, and code, along with instructions. But let's get oriented first!


Step 1


Step 2

Login with these demo credentials.
Username: demouser
Password: demodemo

Feel free to experiment here, but note it's a shared demo account and you may see cues from others.


Step 3

After logging in, you should see the Events* page with a Demo Sound Event already listed. Click the "Details" button next to it.

*In Cohort terms, an Event is a repeatable audience experience, analogous to a theatre production. An Event holds sound and video files, and cues to control them.


Step 4

You should now see an Occasions* list with a Cohort Rehearsal pre-populated. Click the Cohort Rehearsal button.

*In Cohort terms, an Occasion is a specific instance of an Event, analogous to an individual performance or rehearsal.


Step 5

Now we're inside our Cohort Rehearsal occasion. This occasion may appear in one of two states: open or closed. Because demouser is a shared account it may have been left in either of these states*. To send/receive cues the occasion must be open. If the occasion is closed, go ahead and click "Open Occasion". If the occasion is already open, move to the next step.

*Opening and closing occasions is like opening and closing the doors to your show.

Step 6

With the Cohort Rehearsal open, you're set up to send cues from this interface. Now we need to create a recipient. Click "Show QR Code". Grab a phone and, using its regular camera app, scan the QR code provided in the open occasion. Click the link to our events landing page that pops up as a result of the scan, and confirm you have your volume on.


Step 7

Keep that open, and head back to your admin panel (either on a different device, or in a different tab). You are now ready to fire the cue by dragging the slider all the way to the right.
