i've recently been getting into backing videos for live band performances, and have been trying to work out how to assign audio tracks to multichannel outputs, specifically i want to have a stereo music track with a mono (or stereo) click track. Any ideas?Not exactly sure what you are looking for here. Multichannel outputs are normally assigned as part of the A/V creation/conversion process. However, individual/combined audio track/streams can be reassigned using the "Properties > Audio Settings" option in QT Pro. If you are referring to the switching of multiple audio tracks (mono, stereo, 5.1, etc), this capability can be programmed using the "Properties > Other Settings" option for the various associated audio and/or video tracks involved. Switching is accomplished using the QT Player "Choose Language..." View menu option during/before playback. (Note: iTunes and iPod players do not include an option for switching to alternate tracks and players like VLC use arbitrary track identifications while the QT Player uses "Languages" for reference.)

Multi Channel Audio Instrument [Kontakt 2]: Auxes not working?
Hi,
I've searched the forums and come up with several posts about using multi-channel audio instruments, but none seems to exactly address the issue I'm seeing (and being confused by). I'm trying to set up Native Instruments' Kontact 2 sampler in multi-channel mode in Logic Pro 7. I perform the following steps:
1. On an available audio instrument object, I click the input drop-down, select Multi Channel -> AU Instruments -> Native Instruments -> Kontakt 2.
2. When Kontakt 2 opens, I load, say, three different instruments.
3. In Kontakt 2's Outpus area, I create three outputs, labelled "st. 1", "st. 2", "st. 3". I cable these to "Plugin Output 1" and "Plugin Output 2" for st.1, "Plugin Output 3" and "Plugin Output 4" for st.2, "Plugin Output 5" and "Plugin Output 6" for st.3.
4. In Kontakt 2, I assign the output of instrument 1 to st. 1, the output of instrument 2 to st. 2 and the output of instrument 3 to st. 3.
5. Back in Logic Pro, I create two new (stereo) audio objects and assign them to channels Aux 1 and Aux 2 (and name them accordingly).
6. In my Aux1 object, I select its input drop-down and choose Instrument1 -> Kontakt2 3 & 4.
7. In my Aux2 object, I select its input drop-down and choose Instrument1 -> Kontakt2 5 & 6.
Okay, so basically I'm set up now, right? So to test this out, I set the MIDI receive channel of all of my instruments in Kontakt 2 to omni and click on the built-in keyboard in Kontakt 2. I can see the volume level indicators on all three instruments light up. I can also hear all three instruments coming out of my speakers. However, when I look at the environment page where I've created these objects, I find that they're all coming as a stereo sum from the original audio instrument object. The Aux1 and Aux2 objects are just sitting there doing nothing.
What gives?
Dual 1GHz PowerMac G4 (Quicksilver) Mac OS X (10.3.9) MOTU 828Okay, I found the solution to this, and it's odd enough that I figured that I'd post it just in case anyone else ran into it.
It turns out that the multi-channel thing does not work at all when you play Kontakt 2 from the built-in keyboard (in K2). Visually, K2 still shows all the audio going out on the corresponding channels, etc., but I guess it's summing it and outputting in stereo only when you do that. If you send it data from Logic, it works just fine. So I had this setup correctly all along. -
I've been trying to follow various tutorials for setting up multi channel audio insruments and I always get stuck at the point where you select Output 3-4, 5-6 etc. from the Aux 1, 2. 3 etc. objects. I never have more than Output 1-2 to choose from. I usually use the built- in audio or sometimes a Lexicon Omega. Do I need another interface to accomplish this or am I doing something wrong. I've accomplished quite a lot of things with Logic, but this has been hanging me up for a year now. Any thoughts?
Thanks,
Tom
G4 iMac 1Ghz Mac OS X (10.3.9)multi channel audio instrument doesn't require a special card or interface
any interface with stereo output should work
you need to make sure your audio instrument supports multi channel
logic pro only has Ultrabeat and EXS24 as multi channel
under the plug-ins choose multi channel instead of stereo or mono then choose what ever is under multi channel
example BFD, RMX, KORG LEGACY and other 3rd parties that support Multi

Multi channel audio outputs from a laptop such as 5.1 or 7.1
is it possible to get multi channel audio outputs from a laptop such as 5.1 or 7.1 for watching Movies or television while using Windows media Center.
Ok so i order to help anyone who is interested.
The only ironic solution to this problem i found was to use a plugin called xto7 to convert the xml to the old fcp7 format.
i then imported this into premiere pro.
this was then able to export an OMF that when imported into logic 10 that was using the correct 6ch mono setting as separate tracks.
Insane but it works until Apple fixes the incorrect meta data import in FCPX that sets the xml export to the default import that is always surround.
this is the only way i was able to send stems with all the edit points and fades for the sound editor.
If you don't have premiere lying around you maybe able to do it with fcp7 too we just didn't have it in this studio.
Fingers crossed Apple fixes the fcpx xml export. -
Premiere CS6 - MXF export with 8 channel audio does not export my audio channels correctly
Hey Volks,
when i try to export an mxf file with 8 channel audio, premiere does a kind of main mix in channel 1 and 2 and channel 3 to 8 remain silent. It does not include my assignment of audio channels in the mxf file.
im very thankful for any idea...Hi Dast Media,
Have you resolve the multi channel export?
I have the same problem...(the export it's ok but i hear only the first two tracks)
i need to export a MXF file with 8 tracks, 6 stereo and 2 mono.
Thank you for help! -
This is a very simple question about multi-channel audio playback
I have an mp4 file that i made and i made it 7.1 surround sound, and i'm pretty sure that this 7.1 surround sound works, as it can be played in VLC. i'm using netstream to load my files now. How do i make it so that flash can playback all 8-channels of sound? I suppose kglad would know the answer
Flash doesn't support multi-channel audio (yet?)

Can AAC be used to encode multi-channel audio, such as DTS-HD Master Audio?
DTS-HD Master Audio is an optional audio format in Blu-Ray. It uses lossless compression.
There are other audio formats from Dolby Digital, for example, that are used to encode HD audio in Blu-Ray. Can AAC be used to encode those as well, without any loss of information?
Is there any work in progress to make HD audio such as DTS-HD Master Audio available discretely on disc, like what the older DVD-Audio format made possible for 5.1 channel surround sound on disc?
Thanks.What adjustments do you want to make?

No multi-channel audio from DVD Player or Quicktime?
I have the A52Codec 1.7.6 installed. The codec preferences are set to output multi-channel audio. I have my Audio MIDI setup speaker configuration setup for multi-channel audio and the speaker assignment tests are all perfect. VLC plays back files with AC-3 soundtracks in perfect 5.1 multi-channel sound. Final Cut plays multi-channel audio properly as well.
When I watch a DVD, it is decoded to stereo. The dialog on 5.1 always comes from the left and right speakers and never from the center channel. It doesn't matter whether I remove the A52Codec and try again the result is aways the same, 5.1 audio in Quicktime and DVD Payer gets decoded to stereo. It is not that extra channels are missing, if that were true I'd get no dialog at all.
What do I have to do to make the DVD and Quicktime multi-channel audio decode as multi-channel audio and not stereo.I'm not sure if this will resolve your issue or not, but have you configured it using /Utilities/Audi MIDI Setup ?

I try now for hours to export an MXF op1a with 8 channel audio from Premiere CC2014.1 and with AME 2014.1 to copy the file on my XDCam drive u1 to a disc.
The file is always asynchronous after 20 or 30 minutes. The project is synchronous and also other codecs are synchronous if I export them. So I think it's a bug...
I use the newest Sony XDCam drivers. Also parts with no audio can't be render with intelligent render. If I use this option, Premiere or AME crashes...
I work on a mac system with 10.8.5 OSX.
Does anybody have the same problems or any ideas to solve my problem...
Best regards,
FlorianThe following will answer both your questions a) and b).
Click on your master timeline and press cmd+0 (zero) to bring up Sequence Settings, then click on the Audio Outputs tab on the right. Click on the Outputs option and change it to 6. You can leave them as Stereo pairs.
Now, back on your timeline, you need to make sure all your audio is organised so each track. A1, A2, A3, A4 etc has all the relevant media on it.
Then, on the left of the timeline you see the Destination toggle buttons, then you see the Padlocks to lock tracks, then you have the Toggle Auto Select squares. If you right-click on the Toggle Auto Select squares you bring up a little sub-menu, at the top of this list you'll see Audio Outputs, which will show the stereo channels for that particular track. As you've changed the number of Audio Outputs in the Sequence Settings, the list will show: 1&2, 3&4, 5&6. You just tick whichever channels you want.
In your case, you have dialogue on the first 4 tracks, no problem, just go down through tracks 1,2,3 and 4 as described above and assign these to Audio Outputs 1&2.
Then just go down through your music and effects audio tracks and assign them accordingly.
Now, when you export your timeline as a self-contained media file, it will have different audio channels.
I hope that makes sense. When you change the number of audio outputs as described in the first step, I believe the rest of it is fairly self explanatory, once you know where the settings are. -
Multi-channel audio mapping and adjusting.
Hello All,
I am trying to understand the concept of multi-channel audio and the way premiere handles the files.
I have an MXF file which contains 4 channels of audio. I am able to get premiere to view all 4 channels with an adaptive track, however, how do I make adjustments to each track?
EX: Say I want to adjust one of the channels within that adaptive track, how would I do that.
Former FCP user thanks you.

Multicam editing with multi-track audio?
Does anyone know how to do multicam editing with multi-track audio? Apparently, the multicam editor can only see Audio Track #1 in the Source Sequence. I tried mixing my original audio tracks #1, #2, and #3 (submixes) to the master audio track in the Source Sequence and if I listen to the new Multicam Sequence (the nested Source Sequence) all 3 original audio tracks are there (combined), but when I go to do the multicam edit in the multicam monitor window, I"m back to just Audio Track #1 of the Source Sequence and audio tracks #2 and #3 are missing ??? Thanks for your help!
I have run the gambit of different techniques. The one that is most efficient is listed in Colin Brougham's response number 9
There's a far easier way to do this: after you sync your angles, hold down Alt/Opt and select or lasso just the video portions of the clips, and nest those. The audio stays put, but the video moves into the nest, and you can then enable Multicam on the nested sequence.
One of the best things about this is that it circumvents Premiere Pro's totally BS "Render Required Files" nonsense.
I must admit the ALT lasso tip was one of the best features I have seen. Like a revelation when I discovered it some months ago while watching a tutorial about something not related. As far as the "Rendering required files" That was kicking my but for a while doing multicam editing. If you do edit both audio and video in multicam you might find the "Rendering required files" issue. Basically the problem stems from having a lot of cuts to process at the same time both audio and video. 1080P is a huge amount of data when you multiply it by four cameras plus multiple audio cuts and effects ,(audio gain, Deessing etc.) So Pre-rendering the audio by clicking in the main sync timeline and then at the top Click Sequence/Render Audio.This takes care of the issue when you are cutting multiple tracks at once. It is a good practice to work from a main sync sequence and then copy that to a new sequence preserving the main sequence as unchanged. I found the solution is to "render audio" only in the master sync sequence this will then pass through to all subsequent copies that are made "downstream" allowing you to easily clean up anything. If you make a mistake you can always start from the main sync sequence and not lose too much time. Takes a little bit of time to render but once that is done you can cut all tracks video and audio like butter. I have been doing a lot of 1080p multicam editing over this past year and had quite learning curve. Most of the work I do is multicam editing by choice it is much faster for me to edit this way because I am used to working in live events where we need to look at all shots at the same time make a "best choice" and keep rolling. Have fun with it! -
Wanted: Multi-Channel Audio Interface for iMac & GB (USB)
I am looking for an affordable multi-channel audio interface for my iMac for use with Garageband. My goal is to playback old songs from my old computer (Atari ST) through my Yamaha gear and record the audio into GB so I can mix it. (READ: Not interested in transferring MIDI.)
My goal is to get at least 4 and ideally 6 channel/track recording in GB. I’m not sure if the multi-channel units I see, such as the Alesis MultiMix 4 or the Behringer Xenyx Q802USB send all channels to the Mac or if they mix it down to two channels first.
I’d prefer to mix all the channels in GB rather than pre-mix it. Also, I’d prefer to have 1/4” jacks; XLR would be a nice bonus. USB; since Firewire is going away and Thunderbolt is too new.
Any suggestions? I’m trying to keep this under $100. (Also, I know I can use multiple low-budget devices and aggregate them in Audio/Midi, but I do NOT want to go that route.)
Thanks.As you imply, keeping it below $100 makes it tough.
Generally only the two channel interfaces are close to $100.

Hi ...
I'm finding working with multi column\row text box ("table") in Illustrator CS6 really irritating and non-intuitive. Maybe just my ignorance but I can't find simple ways to do the following:
1. Click in a different cell of the "table" to the one currently active. Cursor does not move to new cell. How do I move focus to a different cell?
2. Begin entering text in an empty table - I can't get the cursor to appear, despite clicking inside cell area, on text box border etc.
Is there any simple way to perform these basic, simple tasks?
Thanks
RichardIn my quick test I was able to enter the text by beginning at the upper left of the box and clicking. When I entered the text it appeared in the first box. Then I was able to tab through to the other boxes.

i am trying to output a wav file from a avi file.
this file has multi channel audio, in this case 4 channels, though when outputting the audio by
After Effets, mono or stereo is the only available choice.
In this case, which channel will be extracted from the avi file?I'm 99% sure that only the first 2 channels will be imported. I've seen some weirdness where multichannel audio has been bounced to a stereo pair on import causing a jump in levels. Your best bet is to use Soundbooth (or Premiere) or an audio/editing app to do the conversion.

New logic user, need help with multi-channel inst and aux strips.
Greetings all,
So I just purchased a new Mac Pro 2.66 and Logic Pro 7 to run with it. I have been a long time Nuendo/Cubase user on the PC side of things but since I got the Mac I wanted a DAW that was supported fully for the apple platform.
Anyways, its a world of difference and I am very confused as I wrap my head around the learning curve, so in the meantime I have one important question maybe some one could help me with.
The question is regarding Aux channel stips for Multi channel instruments. In this scenario I am working with Battery 3, it took me a while to understand that I actually needed to create these aux channels just to have seperate outs in Battery which seems really wierd and overly time consuming.
As an example in Nuendo once you create the instance of Battery, the audio mixer automatically just creates the corresponding stereo and mono channels instantly. This obviously makes is a sinch to assign Batteries pads to seperate outs for eq/comps for seperate sounds.
Now the Battery manual doesnt even make a reference to Aux channels for assigning outs in Logic, I actually had to do a Google search to figure this out.
Anways, sorry for rambling...
Here is the main issue.... How can I quickly and easily create multiple Aux's? In the mixer there is really only enough room in there to add like 1 more Aux strip, if I want to add more than that I need to re-arrange the entire global mixer which seems like a crazy system, surely there must be a more convenient method for getting muti-channel audio instruments set up quicker.
Any help you can assist with would be exceptional!
Thanks in advance.Not sure what exactly your question is, especially since I don't use battery. But as far as creating aux tracks:
• go to the audio layer of the environment (not the track mixer window), find the two defalt aux tracks
• Highlight all tracks to the right of the aux tracks (these should be bus and output tracks), and drag to the right far enough to fit in a bunch of aux tracks; you might even want to drag the all underneath the aux tracks, if your screen accomodates
• use the key command shift-command-a multiples times to create several new "audio objects", and double click each one to expand
• highlight all the new objects and select options/clean up/ align objects (makes it look nicer)
• still highlighted, over in the parameters section (left side) select a channel, setting it to the highest number aux (at this point, probably "aux 3")
• now individual set the channel for each aux track – you'll see that now you have available "aux 4"; next time you set a successive track you'll see "aux 5" and so on
• once you've got things set up the way you want, save it as a template so you don't have to do this again later
