Aggregate Device Not Recording Both Inputs

Hi,
I'm trying to run two audio inputs into one (A usb mic and the built in input) on my early 2008 macbook pro. I'm trying to use the Aggregate device function on the mac. Ill create the device and try to test it out in either quick time video/audio recorder, or audacity and when i look a tthe live monitoring of the input (aggregate device) it looks like its working fine. Ill test each input and make sure that its hearing each and it does. But whenever i record something, again in either audacity or the quick time, it only records one of the inputs. Im losing my mind with this problem and ive tried everything. Ive tried switching the **** source around in the aggregate device window and ive messed with the drift functions, whatever those do. Please help, can't figure this out and i need it fixed asap

1) How have you concluded that the Built In input isn't there? - No sound (which I do get if I manually select the very same 'Built-In Input' source in Logic).
2) Are there only 3 pairs of inputs when you use the Aggregate Device? - Not sure what you mean. It's as shown in the screenshots.
3) Have you tried all available (pairs of) inputs from the Aggregate device (should be 8, or 4 pairs) in Logic? - Not sure what you mean. In Logic I am merely selecting the Input Device source in Preferences - I select Sapphire, Built-In Input all OK; select Aggregate and it doesn't recognise the Built-In input.
4) And what kind of signal are you feeding the built-in input. - Line out from my eDrums (sep. right and left channel into single, stereo input on my iMac). Again, works fine but only when I manually select 'Built-In Input' source in Logic.
Incidentally, just tried making the Aggregate Device the 'use this device for sound input' master (with and without Drift Correction for In-Built Audio selected) and... no change.
What I mean and what is crucial is to know, is whether you have set your track(s) to the right input(s). On my screenshots you see how it should also look for you on stereo or mono audio tracks. 8 mono or 4 stereo inputs.

Aggregate Device not recognising Built-In Input

How do I get my Aggregate Device to recognise the ‘Built-In Input” in my iMac?
In the Audio Devices window, I have set my Aggregate Device to be the sound input master to allow me to choose ‘Aggregate Device’ as the Input Device in Logic Pro X .
This, I presume, means I do not have to switch between devices such as ‘Line In’ and my audio interface (Saffire) within Logic. I can just set it to ‘Aggregate’ and happily switch between tracks with different input types automatically catered for by the aggregate device.
However, although the ‘Aggregate’ selection in Logic recognises my audio interface input OK, to use my iMac’s own ’Built In Input’ I am forced to manually select ‘Built In Input’ as the Audio Input - the Aggregate setting does not seem to be recognise it and I can’t figure out why. Everything else seems to work fine.
My set up: In the Audi Devices window, my audio interface is first in line, with the ‘Built in Input’ next. Both are selected for Use. The audio interface is set as the master clock and has no Drift Correction enabled. The ‘Built In Input’ has Drift Correction enabled. All devices are set to the same sample rate (‘Format’).
Thanks.

Aggregate Device not working

When I put 3 microphones and a midi keyboard into a powered hub, each microphone will work properly when accessed individually, but when I try to use an aggregate device with those microphones I get no input at all. It works fine on my older MBP, but will not work with my new one (only 2 months old). It worked with a new unit at the Genius bar, but no Apple technicians seem to be able to figure out why. The logic board has been replaced and still has the same problem. What else might I look for?

I launch GB.
Select New Podcast Episode, create it.
Open Preferences, select Audi/Midi, select Aggregate Device, close Prefs.
GB says it's using the AD but one mic is ignored.
When creating the AD the settings are 44100.0 Hz and 2ch-16bit.
I've tested the USB ports with Plantronics headsets separately -- all work, nothing inadvertantly muted.
Aggregate Device isn't aggragating when the two mics are connected even though they are both seen in Audio/Midi Setup. One mic is ignored completely when I select the AD in Preferences. On the MacPro's left side, the USB port nearest the palm rest is the only port working (when attempting GB with the AD).

Help? Aggregate devices not working in Lion

Since buying a new Mac Mini Server for my audio work using Logic Pro 9 I cannot use aggregate devices. The system preferences as well as audio midi setup will not remember my aggregate devices that I create. Also when using them the audio becomes glitchy and a terrible noise happens. I didnt have any issues like this in 10.6.8. I cannot believe that Apple would let this happen for so long. There are many people in the pro audio world that rely on using aggregate devices and with them not working three versions into Lion this has become maddening.
This is not a third party issue. This is not a hardware issue. This is a serious problem that takes the saying that "Macs just WORK" and flushes it right down the toilet.
I spoke w a guy named Steve at Apple pro audio and he couldnt get me off the phone fast enough. What the ____ Apple??
PLEASE someone fix this? I wont try 10.7.4 as it seems to make Logic work even worse.
Please...I do not want to have to go back to using pro tools and PC's.

please and thanbk you Eriksimon! Full details - Mac Mini Server running Lion 10.7.3, Logic Pro 9.1.7 I use up to three Metric Halo 2882+DSP 2d units with the latest MIO console, drivers and firmware. Many other Metric Halo and other multiple device users are experiencing this and it is maddening. Ive been on Logic since 7 and am a analog-digital component level tech / electronics engineer / audio engineer with a decent knowledge of software.
I also use up to two McMix (now Avid artist mix) with latest version of Eucontrol as well as V-control pro with my iPad to control Logics transport etc when not in control room and a Novation sl49 compact USB keyboard with latest Automap version All that worked together quite well on 10.6.8 - logic 9.1.5 on my late 2008 Mac Book Pro but that system was slow...so I was hoping that Apple had Lion "in a cage" when I went out to buy this new Mac Mini Server.... I guess I should have waited.
I am having these aggregate device problems on a totally new from Mac Store Mac Mini Server Quad Core i7, did a clean install of Logic and the Metric Halo software /driver /firmware package.
Nothing else installed on this new Mac Mini but Logic 9.1.7 and MIO package.
Please....help get this bug fixed??

Aggregate Devices not working

Whenever i make a new aggregate device, once i close the Audio/Midi Setup, the Aggregate Device is gone. It wont open in Logic and if i reopen Audio/Midi Setup it isn't there....only the default. What should i do?

I'm having the same problem. I'm trying to use Ardour (free digital audio software) and you have to do some very specific things with the Aggregate device to make it work, but whenever I make one its gone the next time I open the Audio/Midi window.
Anyone have any answers on this issue?

Help/Advice on Aggregate Devices

I've been recording a podcast for a few weeks on my old Windows laptop using one microphone shared between all four of us participating, not ideal as you can imagine.
I am now a MacBook owner after many years of ******* and so decided to try and use an Aggregate Device to record from multiple mics but I am having a problem with a buzzing noise from one of the inputs.
The mics I am using are a Microsoft LifeChat headset and a Logitech USB Microphone. When used individually both work fine and give no problems. Once combined as an aggregate device the Logitech is fine but the LifeChat mic has a constant high-pitched buzzing/ringing on the track. I've tried messing with sample rates, re-sample etc but can not seem to eliminate this.
Am I wasting my time here and better just looking at picking up a cheap pre-amp?

OK, what I hoped would work does not
But one thing that could simplify bringing your copies from the flash cards into the structure and naming they should be to be recognized by your current catalog:
If you imported them into a temporary catalog, using the same naming and destination folder logic as when you originally imported them, this would bring the files into (or close to) the correct folder structure. Then in the main catalog, they could be reconnected easier if necessary at all. If you did have some kind of a date-based folder structure and did not do too much manual renaming, this should work quite well.

How to use an Aggregate device for Garageband (iLife '11)

Here is what I have,
Komplete Audio 6 interface (USB)
M-Audio Mobile Pre interface (USB)
2010 Macbook (white) running OS X 10.6.8
Garageband from iLife '11
I found out (supposedly) how to use both of the interfaces together by creating an Aggregate device.
I have gone through all the setup steps to create an aggregate device and put both interfaces on the Aggregate list to be used.
HERE IS WHAT I'M TRYING TO FIGURE OUT!
When I open Garageband and designate the Aggregate device as my sources of hearing and recording (Input and Output), the M-Audio doesn't even register sound. When I hook up the M-audio interface by itself, it works. Same with the Komplete interface. They work perfectly individually. But together, Garageband only recognizes channels 1 & 2 coming from the the Komplete interface.
1) How do I make it so both show up as recording to Garageband?
2) How can I hear them in my headphones (monitors)?
Thank you!

Maybe an alternative would be to put this logic into the select.
select u.object_name,
       u.object_type,
       count(case when u.object_type = 'TABLE' then 1 end) over () count_tables,
       count(case when u.object_type = 'VIEW' then 1 end) over () count_views
from user_objects u;This would count the number of tables and views in the data dictionary. And it is returned as a column value.

Aggregate Device "3/4" won't work in Garageband

Last week, we tried to create an "Aggregate Device" out of 3 or 4 microphones. One was the macbook's built-in mic, one was a USB headset, and another was a desktop microphone. This setup worked fine, and worked very well for our podcasting needs.
However, when we tried to record this week, Garageband wouldn't allow us to use all of the inputs. We would select the "Aggregate Device (3/4)" option from the menu for track settings, and it would constantly just switch to "Aggregate Device (1/2)". Playing around with the different recording settings allowed the USB Headset to record, but it wouldn't allow to do all of the inputs we had specified. We've tried everything, from setting up a new Aggregate Device to recording with alternative programs such as Audacity, and have had no success as of yet. What do we need to do to fix the issue? Is this a driver-based error, a software bug, or is it possibly an issue with CoreAudio?

So I only need the MIDI out cable plugged into the INPUT port on my keyboard?
No, the other way round: From the keyboard's OUT to the interface's IN.
I looked at the GB's preferences, and yes, it says that there is 1 Midi device recognized. However, it's strange that this happens before I even plug the Midi cables into the keyboard.
That's perfectly o.k. The midi device is the interface - the computer can't know whether there's something plugged into the device's input.
Oh, and by the way, the thunks I hear when I test the Midi connection in Audio Midi aren't distinguished between different keys. It's one constant note for all of the keys.
I think that's how it's supposed to work - it should just indicate that there's midi data coming in.
Here's another test: If you switch the LED display that normally shows the position of the playhead to the tuning fork symbol, it should display the notes and chords that you play on your keyboard - does that work?

Snowball USB Mic not recording

Hey Guys,
I have a Mac 0S X 10.6.8.
I just boght a Blue Snowball mic-
I'm using Adobe Premiere Pro CS6 and I can't record with my usb Mic: When Im doing overvoice, it is recording with my internal Mic-
I already:
-check the cable
-Connect diconet my computer
-Check the USB port
-create a new aggregate device
-Check out the input and output
-In CS6,Change the audioharware to the new device(256-521) input-output
- recording in mono....
and still I can't figure this thing out-
Can somebody help?
thanks guys appreciated

Hi D.A.,
Sorry you couldn't find the doc easily, but happy you are set up now.
I did place it in our FAQ here: http://forums.adobe.com/thread/1417831?tstart=0
I will let the tech writer know about the need for having this info in the documentation. Good idea, thanks.
In the mean time, you can file a feature request to make USB mic setup a lot easier here: http://adobe.ly/feature_request

I cannot get MainStage 3 to find the Aggregate Device I am trying to use for input. I have two USB interfaces and need to use both for input.

The MainStage 3 Audio preferences window will not find the Aggregate Device input. I have both an Apogee Jam and a MOTU Mike Ultralight in USB ports. The Audio aggregator finds them and treats them as one device. The Aggregate Device does not show up in either Logic or MainStage. However, unlike Logic, MainStage does not show "System Settings" an input device.

The iphone 3G can only support 4.2.1
There are no newer updates availabel for this model.

Connecting 2 USB Devices for recording in GarageBand blue yeti and M-Audio Mobil pre. will they both work together one track each?

I Have set my Audio Midi Setup under Audio Devices to Aggregate Devices and selected M-Audio MobilPre USB and Blue Yeti Microphone.
I plugged my MobilPre into one USB port on my MacBook and the Blue Yeti Mic into the other USB on my MacBook. So I have two inputs
and I set each device for OUTPUT as the HeadPhones from the Blue Yeti Mic. I still cannot record the vocals on the blue yeti and the Guitar on the MobilPre
At the same time even though both show the rec button is active on both. What do I need to do to get these to both work recording at the same time?

I'm not sure what you mean by "mixed with audio in Alsamixer". Can you clarify?
With that said, my problem did mysteriously fix itself after some update (presumably to alsa). Unfortunately, I noticed it in passing one day while I was changing the volume of something in pavucontrol, so I don't remember the exact update that caused it to work. But yes, my current setup does work now: I can listen to audio through my DAC and use the Yeti for recording. However, I have found that use of the Yeti crashes Google Hangouts, although it works perfectly in every other program I've tried.
As documentation, here is my current working setup (it is very similar to the above): in PulseAudio, the DAC is set to be a Digital Stereo (IEC958) output. The Yeti (called an 'Integrated Rate Matching Hub' in pavucontrol) is set to be an Analog Stereo Input. In the input devices section, I have the Yeti's volume set to around 58% (-14.31 dB), which is past the base volume a fair ways but produces decent levels for recording. The DAC's volume is set to 100% (0dB gain, the DAC takes care of the level). In alsamixer, I have the mic level for the Yeti set to 40.
Edit: This is a long-time-later edit, but let me say that when you have multiple USB audio devices, what USB hub and in what order they are connected seems to matter a great deal. If you can't get your Blue Yeti to work, try moving it to a different set of USB ports (controlled by a different controller) on your motherboard. This magically fixes the issue for me.

Logic Mics, Aggregate Devices and The Input Issue

There is a lot of discussion about Logic's inability to accept simple microphone inputs, and I ran into this for two frustrating DAYS of trying all the things in the Logic Express 8 Docs to fix it—to no avail.
But now it is solved, so I'm trying to create a DEFINITIVE list of steps and principles here so others may quickly blast past this issue.
The equipment I have seems to be emblematic to the problem. The Blue Snowball is one of those USB mics that simply doesn't automatically show up in Logic's Preferences > Devices > Core Audio >Device list. The fix for this is never mentioned in the Logic manual or Getting Started docs that I can find. There is a passing reference on page 100 that is virtually zero help, and does not bother to mention how this Prime Gotcha can bring you to your knees.
Principle #1: Logic uses the Preferences > Devices > Core Audio >Device (list) process to identify which microphone you can record with. The list has to have in it an entry that makes sense for both the incoming audio and the playback path that Logic uses to feed earphones or an external monitor.
Normal items on that list look like this:
Built-in Output/Line Input
Built-in Output/Digital Input
Built-in Line Output/Input
Built-in Line Output/Digital Input
Built-in Digital Output/Line Input
Built-in Digital Output/Input
The Built-in Output is the computer’s inner speaker or headphones. The Built-in Line Output is the computers stereo jack for feeding to an amplifier. The Built-in Digital Output is the fiber optic feed that can also feed an amp with up to six parallel audio channels (okay, 5.1 channels).
Nothing on that list will show a fully functional USB microphone that is being viewed on the computer’s System Prefs > Sound > Input page, even though the metering dots there show that the computer sees a live, active microphone.
Selecting the Mic in the Sound prefs page does nothing to pass it on to the Logic > Preferences > Devices > Core Audio >Device list of selectable items. This is frustrating, since GarageBand sees the live mic without any problem, but GB is a simpler program that has fewer options while Logic has many other potentials, so a one-size-fits-all solution may not be its best default setting.
To get the mic into Logic, you have to go into the Audio MIDI Setup utility program where a peculiar option appears that is called “Aggregate Device”.
This keyword is not found in the Mac docs, and understanding it seems to be a big secret. Even the Audio MIDI Setup help page will show you how to find it, but not how it works or how to use it for Logic. Ahem.
You open Audio MIDI Setup and under its header bar Audio is only one item, sure enough, Open Aggregate Device Editor. That opens a window that has two sections, an upper window with Aggregate Devices / In / Out across its top, and a lower window that shows all the options that the computer is aware of. The lower window is called “Structure:” and columns show Clock / Use / Audio Device / In / Out / Resample.
A default item “Aggregate Device” shows in the top panel, and you can add others and double click on one to change its name. You can make many variations here.
By default these will be present:
Built-in Line Input
Built-in Digital Input
Built-in Output
Built-in Line Output
Built in Digital Output
At the bottom of this list any other audio input devices that are plugged into the computer should show up. If they can be seen in the System Prefs > Sound > Input page, they’ll be here, too.
When I plug my Blue Snowball USB mic into the computer, it shows up here as Blue Snowball.
You create an Aggregate Device by clicking on your sound source, in my case, the Blue Snowball, then adding one or more other options.
When you click the Use check box for any entry, it pops to the top of the list.
Principle #2: An Aggregate Device is used by Logic to “see” both an audio input and an audio output path at the same time. The Device you’re creating at this point must include an input Audio Device AND at least one Output item to be fully functional for Logic. A Help page in Audio MIDI Devices called “Combining multiple audio devices” explains this in bare bones, but you can’t see that help page unless the Audio MIDI Devices utility is open.
In my case, I’ve checked the Blue Snowball and Built-In Line Output, so I can use that combo in Logic to define where the mic is coming from and where the Logic audio output should go to my line-input amp and speakers.
In the Audio MIDI Setup utility, simply selecting the Blue Snowball as the “Default Input:” device and/or the “Properties For:” options shows that the Audio Output area of the page has this cryptic message: “Output is not supported.”
At this point, you’re almost ready to go, and you can close the Audio MIDI Setup utility. But there is at least one more “gotcha” to conquer.
Principle #3: Logic ONLY looks for its list of usable Core Audio Devices when it starts up. If you have it open right now, all the choices made for Aggregate Device will not show up as selectable. Save any work in Logic, shut it down, then boot it up again.
Now you can use Logic's Preferences > Devices > Core Audio >Device list to see your Aggregate Device. I’ve named mine “Snowy Line Out” to trigger my recognition of what it contains. Another one is called “Snowball + Line + Digital” and it has both line and digital outputs aggregated to the Snowball mic input.
You can make one in the Aggregate Device Editor that combines a microphone plus earphones (Built-in Output) plus Line and/or Digital Outs, too. You'll have to switch among them in Logic as you work, but each will carry the live mic direct to recording.
I hope this gets you through the frustration of not knowing what to do when confronted with the lack of clear docs and complete steps to get a USB mic or other seemingly opaque input issue. Feel free to add to this so others in my former state of bewilderment can gain understandings.
If Steve Jobs were to encounter the level of opacity, ambiguousness and frustration that setting up a simple USB microphone can create in Logic, you can bet that the several programs and their intimate interdependency would be either automated or fully explained in the documentations that followed his fiery analysis of the issue.

I don't know of another way to get the Blue Snowball USB mic to show up in Logic. If you can do it without having to go through the Aggregate Device route, feel free to post here how to get that to happen.
I didn't have a different mic available when I started trying to do what seemed to be the simplest of things -- record and play back an audio track -- and nothing else seemed to work.
There are a lot of Aggregate Device threads around here, many associated with Blue Snowball, Blue Snowflake and other things, but none of them laid out the principles of how Aggregate Device Setup needs to work or what to do to force it into compliance.
As I said, the clues in the Logic docs and in-mac docs are minimalist, at best, none of them bringing instant head slaps of success readily.

Audio MIDI setup not allowing aggregate device

I recently upgraded to a mac pro, and transferred everything from my old mac via firewire..
On my previous computer, using my aggregate device (Roland Fantom + Built-in output + built-in input) was no problem. I would simply choose in Logic my aggregate device under the core Audio preferences, and I could play logic software instruments with the roland keys, record audio through the roland, and play it back through the built-in line output no problem..
Now, on my mac pro, I can't do this because the aggregate device I created on my previous computer is not showing up under the devices pull-down menu in the core audio preferences in logic, and I cannot create a new aggregate device on this computer, as a matter of fact I cannot even seem to delete the old one... when i click the plus or minus (+/-), the blue shade highlighting the selected audio device just goes straight to the device at the top of the list (which happens to be built-in mic). it does not even allow me to deselect or select any checkboxes within the existing "9/25 aggregate".. when I try it just makes the devices listed in that window wiggle...
I have attached a screen shot of the Audio Midi setup screen (where one should be able to create aggregate devices)
Please let me know if you know what could be causing this..

Ojan36 wrote:
Could uninstalling and reinstalling Logic completely possibly fix it? I guess that would be unlikely because the audio MIDI Setup window is OS X, unrelated to Logic..
Correct.
when i click the plus or minus (+/-), the blue shade highlighting the selected audio device just goes straight to the device at the top of the list
This is one of the reasons why I am still suspecting some kind of permissions problem, even though you said this user has Admin privileges. I suspect a permissions problem because the symptom you described ("the blue shade highlighting the selected audio device just goes straight to the device at the top of the list") is exactly what happens if you do not have Admin privileges and you press the + button.
I think this issue has to do with the fact that there was not a clean install of snow leopard
I agree. My theory is that something about the way you moved items to this machine led to a permissions problem, and this permissions problem is causing AMS (Audi MIDI Setup) to behave the way you see.
I recently upgraded to a mac pro, and transferred everything from my old mac via firewire..
I know you connected via FireWire, but how did you control what was being transferred? Did you use Migration Assistant, or some other method?
In my comment here, I advised 55plus to check something. What happens when you check the thing I advised him to check?
You have not mentioned Disk Utility. I would use it to Repair Permissions. Then launch AMS. Does the + button work now?
Next I would try this: create a new OS X user account, with administrator privileges, and log in as that user. Then launch AMS. Does the + button work now?
55plus, I intend to respond to you too, but this is all I have time for right now.

Aggregate Soundcard - Device not selectable

I have 2 external audio interfaces (Tascam US-1641 & Zoom R16) installed on my Mac (running 10.6.8 Snowleopard) both connected by USB.
They are both installed correctly and drivers are up to date.
I can see them in my audio preferences and each are selectable as my primary soundcard for input and output. They both work.
In my audio devices page in "Audio MIDI Setup", both devices are visible in the left column, however when I go to create an aggregate device, the US-1641 doesn't appear on the right as one of the selectable devices.
Does anybody know of any reason that a functioning audio interface would not be selectable for use in an aggregate device?

Are you using the universal binary versions of Logic (7.2) and 3rd party drivers?

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. I need all three for a podcast, any solutions?

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. At first I thought maybe the third microphone was just defected or something but I tested the mic individually and it works fine. It'll let me use two Blue Yeti's and another microphone but not three Yeti's at once.

The problem is that the mac chokes on having 2 identical mics attached at the same time.
Ive had 2 identical USB AT2020 mics connected at the same time on both macbook pro and macbook Air.
The "Yeti" mics, are, lets say undesirable, and low to mid computer consumer mics.
