Hi, I very recently ran a show completely in 5.1 surround, all from QLab. It was a theatre show with 5.1 soundscapes and 5.1 soundtracks (in sync with film ran by a Catalist system). There is a big difference between 5.1 and multiple soundfiles that you send to different speakers to create certain effects. When you use exclusivly 5.1 soundfiles (Logic, Nuendo) you always can choose, on a cue per cue basis, wich outputs you want to use. No problem. The tricky thing lies in live editing. You always must go back to Logic, Nuendo to edit your audiofiles - bounce them and put them back in to QLab to play. Live I use a simple MOTU Ultralite MkII in conjunction with a Yamaha DM2000 and a MacBookPro 17", the audiofiles are on a Glyph External harddrive via firewire 800. Never had a problem. Be aware, when you play 3 - 5.1 files at the same time, there are 18 mono files playing !! You better have a good and fast Hard drive.

Hi there,

I need to connect 2 to 4 projectors  and cue them up in qlabs.

I am working on a Mac OS 10.6 Mac book pro 17" with 2 graphics cards if that helps.
Would you have any idea how to work this out please?

Hi Calliope,

Welcome to the list!  (By the way, to post to the list without me needing to approve your posts, you'll need to sign up to the list first.)

Is there a particular step of it that's confusing?  The basic idea is that once you have multiple projectors attached to your computer, each one becomes a screen for the computer and therefore becomes accessible as a display output for QLab.

In your QLab workspace you'd just need to make sure each physical display has been patched to a screen number (in the workspace video preferences) and then you can assign your video cues to these screens in the inspector.

Best,
Chris

Antwoord aan: "Discussion and support for QLab users." <ql...@lists.figure53.com>


Equipment using - Art Tubefire8 firewire audio interface, macbook pro
- currently free QLab version (waiting license for pro bundle).

I've read the posts on here and still have a few questions with
surround sound - I haven't seen answered?  From what I understand my
options are:


1.  Create a surround sound file from Logic Pro (or similar)  -
importing this and triggering this from within Qlab - with and this is
the bit I'm still unsure about - the audio output automatically of the
surround file mapped to the first 6 faders (if 5.1 file)? Is this
correct?

or

2.  Bounce multiple files for each 'pair' of speakers (obviously not
true surround) from Logic Pro and run these together in Qlab.  (I can
except slight timing drift as not critical).

My preference is option 2 - due to not using strict 5.1 speaker setup
- instead having something like quadraphonic but with 6 speakers and
subs?!

The thing I dont understand is this...

(apologies I'm running the free version - awaiting pro license which
may solve this?) - If I use option 2, and run multiple audio cues
together - am I right in thinking that I can still allocate different
sound cues to different hardware audio outputs?  If so, is this done
in the inspector (with the waveform) pull-down list or in the 'levels'
tab in the inspector?  Would this be with the mixer faders or with a
matrix mix?

One final thing - I have an 8 channel interface setup (I realise this
wont work with free version as its limited to stereo) - but in the
'audio setup' - to get the 8 channel output, do I need to patch
devices 1-8 to the 'Art firetube8' or are these a 'level above' and
classed as 8 different hardware devices? (i.e. only plug device 1 into
interface and within that device are the 8 channels 'hidden'?)

Thanks for your help - hope that all makes sense?!  Enjoying the QLab
expereince...

Yes. But see below.

No. When you get your pro license you will see that the matrix allows routing of any channel to any output. So a mono file would be a 1x8 a stereo would be a 2x8 a 6 channel file will be 6x8. Its up to you to dial in the routing you want on a cue by cue basis to each output.

I personally found that its easier for me to design from the speaker back to the source. I decide what I want in each speaker and set up the sources to provide it via the matrix. So I might have some sources go to more than one speaker and others go only to a particular one.  i.e. you can get a kind of "quad" effect from a stereo source by sending stereo Left to front Left and rear Right, then Stereo Right the opposite way. Then you can blend some right and left where needed as well.

Make sense? It will when you get your license.

As Steve said, it'll probably make more sense when you have the license, but you may also want to check out the tutorial on signal flow (http://figure53.com/qlab/tutorials/2-1.php). If I understand your question right, all 8 channels will show up as one device, so you just need one patch into that device, and you'll be routing the individual channels in the Levels tab of the inspector.

I'm wondering if you're trying to connect more monitors than you have
display outputs for.  I recently asked this question, and found that
Matrox makes a product called DualHead2Go that mimics a double wide
monitor and has two outputs, so you can fake two video outs when your
computer only has one.  They also make a Triple.

Hope that helps!
