Faking a looper pedal on stage?

[Florian Staab]

Hi all,

I’m doing a show that wants to have an actor play guitar with himself through a looper pedal onstage as part of the action of the play. However, I don’t think my actor is good enough to do the looping part live, and I would also want to have some music already established via playback, so it feels like he was in the middle of the process. But, it would be great for him to play something simple live and hear it recorded back to get the sense of him creating this music, even if most of it is being supplied from the QLab machine.

So my question is - is there a way to record audio and then play it back again immediately through QLab? Maybe work with Ableton and connect the two via Apple Scripts?
I’ve faked looper pedals completely before with devamping, but I’m not quite sure how to do the half real, half fake thing...

Any thoughts would be helpful, as I’m having a bit of a hard time wrapping my head around this.

Thanks!

Have a look at sooper looper.

I've done this with QLab and REAPER.

I had QLab play click tracks sent to the musician's IEMs so that the loop commands would be synced with their playing.

I also had QLab send midi commands to REAPER (via IAC), which has a midi-controllable loop plugin. Those midi commands were synced to the click tracks the musician was hearing.

I had audio go directly from the audio interface into REAPER, and not through QLab. And likewise, I had audio going directly from REAPER to my various system outputs through the audio interface. In REAPER, you can easily mix your content into outputs as necessary (and change it on a cue-by-cue basis, also controllable by QLab via midi, if necessary).

I'm sure there are other plugins that allow midi-controlled looping, but REAPER has a built-in one (though I forget its name at present... could look back through my show-files to find it if this is the method you're interested in using. For that matter, I can provide examples of all of the above from the show I used it in if you decide to go down this route).

It does take some time to get everything set up and talking as you'd like, but it does work just fine.

If you’ve got Live use that and send MIDI to it from QLab – it’s not scriptable.

I'll post a full workspace in the next couple of days, but I have just rechecked the 64bit AU plugin version of Sooper Looper with QLab 4 and it works really well for almost any' record live audio'/'replay  the recording at any speed,  in any direction' etc. you can think of.

Insert it on a cue output in settings (use a high numbered output or pair of outputs for stereo and matrix those cue outputs to device physical outputs.)

Set up a network destination for Sooper Looper: localhost port 10051

Then when you want to use it route audio to the cue output(s) you are using and initiate the record and playback and any other settings using OSC messages in Network cues.

Thanks Mic!

That would be super helpful. I downloaded a copy of SooperLooper but have not yet had a chance to play with it. Looking forward to figuring this out!

Best,

Here's a simple demo workspace that records audio and plays it back on cue. It shows how you hook up SooperLooper in QLab and how you send commands to SooperLooper through OSC messages.

A full list of the OSC for Sooperlooper can be downloaded here

http://essej.net/sooperlooper/doc_osc.html

You will need to install the 64 bit plugin version of SooperLooper available here

http://essej.net/sooperlooper/download.html

The demo uses the built in output. SuperLooper is inserted on cue outputs 11 and 12 and has a network patch localhost:10051

The routing matrix sends cue output 11+12 to built in output 1+2

If you repatch to another interface you will have to set up this routing for that.

The demo plays a Public Domain Librivox recording to simulate your live input. This is routed to the main audio outputs (1+2) and also to the cue outputs with SooperLooper inserted

 Network cues sends OSC messages to control the SooperLooper plugin as needed

video of it working attached. Demo workspace in next post
