Getting Qlab 3 to control Projector Midi Remote

[Andrew Gaylin]

Hey everyone, 

I'm having little luck getting Qlab to talk to the Projector Midi Remote app.  I'm able to get Isadora to control the shutters to our Panasonic projectors and all, but not Qlab.

I'm not sure what I'm missing.  Any help would be awesome.

Thanks, 

Andrew

Hi Andrew,

When you say you are able to control your projectors with Isadora I suppose you are controlling them through the Projector Midi Remote? Is it the case? 

You may know this already but just to make sure:

To send midi from one software to another within the same computer you need to use OS X's internal IAC Driver.

-Quit Qlab and the Projector Midi Remote

-Find Audio MIDI Setup in Applications -> Utilities

-Double click on IAC Driver

-Check the box "Device is Online"

-Reopen Qlab and Projector Midi Remote so that they can find the new midi port

-Once back in Qlab, go to the preferences and check your Midi patch and make sure one of them is set to IAC Driver

-Then make sure your Midi Note cue in Qlab is sending out (at the Midi Destination field) to the IAC Driver

-At this point the information should make it way to the Projector Midi Remote. 

So if you use the learn function in the Remote and send the cue in QLab, it should work.

One would hope anyway.

Let us know if this works.

Thanks so much Pierre-Luc.  That worked perfectly.  I was trying to set up a midi network and never thought of the IAC driver.

Thanks again,

Andrew

Hey Andrew, what were the steps you used to get this working? I tried Pierre's method but I feel like I'm missing a step.

Thanks

Hi John,

I just tried this again and I realized that I had made a mistake in my previous description. You have to send "Control Change" midi messages and not Midi notes or anything else. That might be your issue.

Hope it works for you.

I just did this yesterday for a two projector show. Here are the steps:

1. Set up IAC driver as described above and assign IAC Bus 1 as a MIDI port in Qlab.

2. In Projector Midi Remote, define the CC parameters for your projectors (or for a single projector, just stick with the default values). 

3. In QLab, create a MIDI Control Change cue with Channel and Control Number matching the values in Projector Midi Remote (usually 1, 1). Set the Control Value in the CC cue to 0 or 127 (i.e. "closed" or "open").

4. Back in Projector Midi Remote, click the Learn button next to the function you want to map (shutter, power), which will turn light grey.

5. Run the function in Projector Midi Remote (set shutter to ON or OFF, etc)

6. Run the CC cue in QLab. If the routing is correct, the Learn button will not longer be highlighted once the CC cue is run.

7. To create a cue that runs the shutter in the alternate manner (open instead of closed) copy and paste the QLab Midi cue and set the Control Value to 127 (if the first cue was 0) or vice versa.

For a multi-projector show, you can alter the the values in Projector Midi Remote and the associated Control Number values in QLab's control change cues to address the projectors individually.

Hey all, just wanted to give you a (very late) thank you for all you help, I can now control shutters in Qlab and Isadora and its a huge relief.

Thanks again!

Hello all, 

I am having troubles with getting a panasonic-pt-d12000 to shutter open.  I have control over closing it but cant get it to command open.  I have tried all fade control values.  Has anyone come across this problem or have any suggestions?
