Record Using Multiple Usb's

Is it possible to record directly into garageband using multiple usb's ( guitar+ vocal mic) ? If yes how so?

You'll have to create an aggregate device in the Audio-Midi Utility. Search the Help for "aggregate" for instructions!

Errors when using multiple USB-8473 devices

I am trying to put together an application that uses five USB-8473 devices simultaneously on one PC. I can't seem to get more than two of them running without getting error -1074388956 (object handle invalid). Any two of them will run together, but when I go from two devices to three, I get the error every time. I have gone through and made sure that the object handles I am providing to ncReadNetMult are the same ones generated by ncOpen. Is there some limit to the number of these devices that can be run at the same time on one PC?
It is not a USB issue (though they are all on the same powered hub) because I am only writing 4 frames/sec on each device and get the same issue without any modules attached.
I need to run five at a time so I can talk to five modules with the same address at the same time.

Marcus,
Can you please clarify your comments regarding the USB hub? Specifically why you believe the hub is not part of the issue? I looked into the spec for the USB 8473 and these devices are rated at 250mA and 5VDC per module. Can you please check the rating of your hub? If you are trying to run 5 modules simultaneously, you will need the hub to output 1250mA to power all 5 modules. One of the common current output ratings is 500mA per hub - thus your ability to run only 2 modules.
One way to eliminate the hub as the root cause is to try to connect multiple modules directly to your computer. I checked on my system and found that each of my 7 USB ports is rated at 500mA each. To check on your computer simply go to the Device Manager and expand USB Controllers. This will let you know how many internal "hubs" are on your system. When you right click on a hub, select "Properties", and click the "Power" tab, you will see the current rating of the ports assigned to that internal hub. If you have 3 (or more) available ports that meet the power requirements, then you should be able to test with three (or more) modules to see if the issue is present without the external powered hub.
To me it sounds as though your hardware requires more current than the hub can supply.

Using multiple usb inputs

Sorry to ask what is probably a pretty amateurish question, but how do you configure two usb mics to function as 2 different inputs?
Both mics are recognized and work individually, but when I plug them in only one functions properly.
Thanks in advance for any advise and assistance.

Indeed I did. I even packaged them both as an aggregate device, and made that device the default for core audio and still nothing.
I suppose I am a little perplexed here and perhaps out of my depth. (previous protools user here) There clearly has to be a way to utilize two inputs, what is the best way to achieve this? Is it the fact that I am using two usb devices in two separate usb ports?
Thanks for your assistance.

Can I use multiple USB mics with Audition?

I have a couple Blue Yeti mics and would like to find a program that allows me to use 3 of them at the same time all recording and allowing their built in headphones to work as a monitor for all channels for a podcast setting. I don't have an advanced soundcard, I have a quad core PC with 2g ram running Vista. So does this work as is if I buy the program or what do I need to make this work if not? Any help is appreciated.

ASIO4ALL will allow you access to all 3 mics in Audition.

Trying to use multiple Blue Snowball Microphones, but Mac only recognizes one!

Trying to record using multiple snowball mics by blue, but the Mac will only recognize one device at a time. Only one shows up in system preferences, and in trying to create an aggragate device. If you have both plugged in, the audio levels freeze up, and the devices become unresponsive.
I have seen similar threads around but no one seems to have any answers. Blue's tech support is closed for the weekend so I can't call them. Please help if anyone has any ideas.

Typically, over USB I can only get my computers (mac and PC) to recognize 2 channels at a time over one source. If your computer is recognizing one and not both or the other when both are plugged in, I think one is all you're going to be able to use. Also, in the system preferences under Sound, if you are able to only select one or the other, I believe all you can do is select which one you want to use.
Those micrphones work well and one should do a good job. Don't forget about Micrphone Phase Cancellation.

Cant hear song playback while recording with external USB Interface Mic in Garageband

Hi there
There must be something wrong with my settings in Gargaeband/Mac Sound Settings.
I have Garageband 9 (V5.1) running a song I have already recorded using a USB keyboard.
I want to record using my external mic and my USB Audio Interface, so
I select New Track> Real Instrument
I plug in my Yamaha Audiogram 3 USB AUdio Interface and I get a pop up stating
"Garageband is scanning your system for audio devices, and has detected a device named "USB Audio Codec"
If you want to use this device do not disconnect it during the scanning process.
Do you want to use this devise No/Yes."
I select Yes and INPUT SOURCE changes from
Mono 1 (Built-in Microphone)
to
Mono 1 (USB Audio CODEC)
I can see the signal lights lighting up on the audiogram 3 when I talk into the mic, so theres no problem there.
Also when I hit record I can record audio using the mic, and can see the levels (and the audio wave I am creating being drawn on the screen) but I cannot hear the track itself when I am recording using the mic. Nor can I hear the track or the new mic recorded audio AFTER I have hit stop.
The only way to hear the song again with the newly recorded mic track is to unplug the Audiogram 3 (Then I get another Pop-up stating
"The audio device "USB Audio CODEC" has been disconnected!
Do you want to switch to Built-in Audio or quit Garageband?"
I select USE BUILT-IN AUDIO)
Then the input source changes back to
Mono 1 (Built-in Microphone)
And I can hear the track again.
So my problem as you can see if that I cant hear the track while recording using the microphone with the Audiogram 3.
But I can record video with audio using the audiogram 3 USB Audio Inteface and mic using photobooth when I select change Sound>Input to USB Audio Codec in system preferences
It therefore assume it must be a problem with the internal audio settings of the mac/garageband.
Can anyone advise?
thanks!

In order to hear yourself while you are recording, you need to set Monitor to "ON" under the Track Info panel.
Also, what are your sound output settings? It sounds like you haven't selected the right output source.
If your speakers or headphones are plugged into your audio interface, then you need to go into Preferences -> Audio/MIDI and select your audio interface under Output as well as Input. If your speakers or headphones are built-in or plugged directly into your computer, then you need to select Built-In under Output.
I have a sneaky feeling that you are in the latter scenario, and that when you plug in your audio interface Garageband is automatically switching both Input and Output over to your interface, which means no sound output as long as the interface is plugged in.

Can you record sound using a USB 6211 and convert the data to a .wav (or other sound) file?

Hello,
I am trying to build a system that will use a USB 6211 to record sounds from multiple electret microphones and then save the data as a .wav file or other sound file. I have already built my mics and hooked the mics up to the USB 6211; the DAQ device seems to do an adequate job recording the signal - I've recorded from 3 mics at a time at 11,025 Hz, although I don't know how good the signals are since I can't save them for playback after the fact, and they aren't going through my sound card. Ultimately, I would like to save the data as a multichannel audio file which I could then open in a program such as Audacity for further editing and analysis. Since Audacity can import a variety of sound files, my file format doesn't need to be .wav if another format would work better.
Any advice would be appreciated.
Thanks, Eric

If you are sampling all three simultaneously, your highest frequency recordable will be (11,025/2)/3, so about 1800Hz and that will pretty coarse (traditionally digital sound recording is at 44Ks/s at the low end). As to converting to a .wav, there are functions on the "Graphics and Sound" palette for saving waveforms to a .wav file.

I am currently using the firewire port on my macbook pro to record dv from my camera. Can I capture video/audio using my USB port as well?ra

I've been connecting a sony PD170 via firewire to my Macbook pro to record directly using Quicktime pro. Can I use the usb port (and mini audio in) to accomplish this with a camcorder that doesn't have a fire wire port but does have USB out?

It could just be a bad disc - I use Verbatim and have only had one fail in a ten-year time period. Try getting a batch of Verbatims and see if you have any problems. I didn't even know that there were Kodak branded discs...

How to get multiple records using fn-bea:execute-sql()

Hi,
I created Proxy service(ALSB3.0) to get records from DB table. I have used Xquery function(fn-bea:execute-sql()). Using simple SQL query I got single record, but my table having multiple records. Please suggest how to get multiple records using fn-bea:execute-sql() and how to assign them in ALSB variable.
Regards,
Nagaraju
Edited by: user10373980 on Sep 29, 2008 6:11 AM

Hi,
Am facing the same issue stated above that I couldnt get all the records in the table that am querying in the Proxyservice.
For example:
fn-bea:execute-sql('EsbDataSource', 'student', 'select Name from StudentList' ) is the query that am using to fetch the records from the table called StudentList which contains more than one records like
Id Name
01 XXX
02 YYY
03 ZZZ
I tried to assign the result of the above query in a variable and while trying to log the variable, I can see the below
<student>
<Name>XXX</Name>
</student>
I want to have all the records from my table in xml format but it's not coming up. I get the value only from the first row of my table.
Please suggest.
regards,
Venkat

Can I use multiple values for a rollup key on the same Endeca record?

We have a business need to to aggregate our records using different criteria, based on user navigation. We are thinking of using a rollup key with multiple values to help with the aggregation, but we are running into some issues.
Here is a made-up xample of what we want to do: assume we have a group of products and these products can be organized into groups using parent-child relationships. We would like to create an aggregate record for each parent, and we want the aggregate record for each parent to include all the children for the parent. To achieve this, we use a field called "parent_rec_spec" that holds the parent record spec and we set the same value on the field for the parent and its children. When we do rollup using the parent_rec_spec as the rollup key, we are able to see one aggregate record for each parent (with its children).
The previous setup worked perfectly for us so far. But now we are getting a business requirement that allows children nodes to be linked to multiple parents at the same time. We were hoping of using another dimension to limit the records based on user roles/characteristics , so that only applicable parents/children are displayed (for example, we can use "market" as an additional filtering property, and we decide to show all parents/children for "North America", while hiding the parents/children for other markets).
This caused an odd behavior when children are linked to multiple parents. For example, assume that SKUs A and B were linked to parents in "North America" and "Europe" at the same time, and assume that the user chose the "North America" market. The navigation state would eliminate the parents/children that are no in North America, and will also cause the parents/children that are labeled for North America to show up and be aggregated correctly. This however will lead to the creation of additional aggregate records for the A and B using the parent_rec_spec values that would have linked them to the Europe parents (even though the parents are hidden away).
Here is an example index file that we used to load the test data:
Update||1
Market||North America
Record Type||Product
Name||Parent 1
rec_spec||P1
parent_rec_spec||P1
EOR
Update||1
Market||Europe
Record Type||Product
Name||Parent 2
rec_spec||P2
parent_rec_spec||P2
EOR
Update||1
Market||North America
Record Type||Product
Name||Child A
rec_spec||A
parent_rec_spec||P1
EOR
Update||1
Market||North America
Market||Europe
Record Type||Product
Name||Child B
rec_spec||B
parent_rec_spec||P1
parent_rec_spec||P2
EOR
Update||1
Market||North America
Market||Europe
Record Type||Product
Name||Child C
rec_spec||C
parent_rec_spec||P1
parent_rec_spec||P2
EOR
Update||1
Market||Europe
Record Type||Product
Name||Child D
rec_spec||D
parent_rec_spec||P2
EOR
In this setup, we have parent P1 marked for North America with children A, B and C, and parent P2 marked for Europe with B, C and D as children. When we use North America as a filter in the navigation state, and parent_rec_spec as the rollup key, then we will see an aggregate record for P1, A, B and C. But we will also see an aggregate record for B and C by itself (presumably because of the other parent_rec_spec value on these records).
The actual data that we are testing with is more complicated, but the end result is similar. We also noticed that the additional aggregate records would not be created always, depending on the ordering of the records.
The question that I need help with is this: is there a way to fine tune the rollup logic so that it can only include certain records (in the example above, we can change the rec_spec from PA and PB to PA_North_America and PB_Europe and then we would be interested in rolling up using values that end with NorthAmerica).
By the way, we considered using separate rollup keys for each context (like parent_rec_spec_north_america and parent_rec_spec_europe), but the number of contexts is dynamic, and might grow large. So it is not easy for us to create the additional properties on the fly, and we are concerned about the possible large number of dimensions.

How to use multiple midi controllers with Mac book pro (2 usb)?

I have a newer macbook pro that has 2 USB ports, and a lightning port and a firewireport.
On stage I will be using the firewire port connected to a Presonus Firestudio mobile to use as the interface to the house mixer.
I will use 1 USB for my M-audio Axiom 61
I will use the other for my Yamaha WX-5 Wind synth
I'd like to be able to get the apogee midi foot controller to control the playback audio. For example I'll be using it to stay in a solo section, then step on it to move it forward ot the next section when I am done soloing
I'd also like to use some sort of midi switch to turn on vocal effects of the mic.
Anyway since I only have 2 USB ports, how should I connect the 3rd, or 4th USB midi controller?
Will a USB hub work to do this? If so, will I always have to remember to use the same controler in the same exact hub input to make sure everything maps the same?
I guess I'll also have to learn how to setup multiple controllers in Mainstage as well.
Thanks
Dan

Hi there,
is a question which many of us have spent ...
I think the obvious answer is that yes you can use a hub and connect everything. however ....
sincerely advise you to buy a good hub that is well feasible, the last thing you want on stage / rehearsal is one of midi controllers stop responding, or stay with hanged notes... etc., do not buy just because it is cheap it has to be stable and viable, some bring cable for connecting wall power just to not drain power from the USB port.
Other things to try is to distribute as much equipment for USB / Midi.
For example one of midi controllers connect via USB but not by Midi outside the Presonus Firestudio. Connecting Presonus Firestudio to a single USB port as it is a main equipment.
but it really is an issue that greatly limits the use of USB devices.
Try it and tell me how it went. Good luck
(sorry for my english i´m Portuguese)

Can I use a USB hub to connect to multiple USB ports from one GPIB-USB-HS?

I have one instrument which has a GPIB-USB-HS connected and the USB cable is connected to a USB hub. Can I have multiple PCs to connect using USB hub at their respective USB ports? If so, how many PCs can I connect using the USB cable?
I have downloaded the latest NI-VISA from the website.
Solved!
Go to Solution.

You would first need a hub that allows you to switch between multiple pc's and then only one pc at a time would be connected and in control.
When you buy this special type of hub, one of the specs is how many pc connections it has.

Insert Multiple records using Database adapter with Stored procedure func

Hi All,
I want to insert multiple records on a database using a stored procedure. I wanted to insert those records using a Database Adapter and the Database adapter should be invoked by a Mediator.
Can somebody suggest me with ideas whether it can be acheived with OOB capabtilities in SOA suite or not?
Thanks for your help in advance.
Thanks,
Shiv

The use case you want to achieve is feature supported by the DBAdapter and it is possible to invoke the same from mediator.
Please have a look at the oracle documentation and you should be able to get the necessary information.
The below links should help you as well:
