Creating seperate audio input and audio output tracks?

I need a bit of advice on how to do this. I'm using a simple Lightsnake USB cable to hook my guitar directly into my computer, now i can record into the program but need to switch between the Unknown USB input and the built-in inputs to get sound. This has made monitoring tracks impossible and is pretty frustrating, any help would be appreciated.

Hi Dennis
Logic Express seems to like a single source in and out, however you can get around this by going into Audio Midi Setup (Applications -> Utilities -> Audio Midi Setup) and creating an aggregate device with which you can choose separate input and output devices. Then, simply choose the aggregate device as your audio driver when you're back in Logic.
P.S. I assume this is still valid for LE8 as I havent got my copy yet
Good luck and may the force be with you

Xbox digital audio input and then output through MacBook digital audio port

Hi,
Sorry if this has been asked before but I'm trying to output a Dolby Digital (I think AC3) signal from my Xbox 360 into the MacBook's digital audio input and then output it through the digital audio output. I can output 5.1 sound from the MacBook itself but I can't get the Xbox audio to pass through. I don't know if the audio is at a sample rate not supported or needs decoding or what!
Any help would be appreciated!

If that doesn't work, I'm not quite sure.
A combination of the Audio MIDI Utility (in Applications/Utilities), SoundSource, LineIn, and Soundflower (http://cycling74.com/products/soundflower/) might work, otherwise I'm stumped. Your best bet is probably a dedicated external USB or FireWire audio interface.

How to use a bluetooth cellphone for audio input and output

Hello, I was wondering how to set-up my Mac Book so that I can use my bluetooth cellphone for audio in and audio out. Ideally, I would like to use my handset for talking on iChat and Skype. Has anyone had any luck doing this? When I bond my cellphone these optiosn do not appear. I know that this is easy to do on a Windows machine but I am not sure about how to do it on my Mac Book.
Thanks!

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

Audio input and output

I am trying to get audio to play through from the audio input to the audio output. I have plugged a line-level keyboard into the audio input and as I play it, it shows that it has plenty of input level in the sound panel of the system preferences. However, there is no sound coming out. I have tried speakers, headphones and the Griffin IMic. If I use a program like SoundStudio3 and click the audio "thru" button it works fine, but it does not work without.
Is there a THRU switch that I am missing somewhere? I tried the Applications/Utilities/AudioMIDI setup to configure it, but the Thru button at the bottom is greyed out (not in operation).
Thanks.

Hi Rich,
Welcome to apple forum.
In my opinion, I don't think OS X have the capability to sent the audio input "THRU" to output directly (I could be wrong).
You need to use Garage band or third party software like you mention before to allow it.
Maybe if you connect third party device that is "supported" the signal become audible and you can hear it. Like mBox using core audio driver.

Good Luck.

Built-in audio inputs and output don't respond to anything.

Hi there,
Maybe somebody can help me, I have a macbook pro os x 10.8, and i'm having a bit of problem.
I connected a cable to the line input, and before i had a chance to balance the high volume the whole software in the system preference froze, and now the built-in audio inputs and output don't respond to anything, also in the audio MIDI setup menu. The volume button moves extremely slow, and there is no sound at all. Anybody has any idea?
Thanks in advance

Sample rate off the audio input and out devices do not match - what to do?

This is fundamental, I know, but nevertheless I can't find my way around it. I get this error message when trying to recor:
Sample rate off the audio input and out devices do not match
and am asked to do this:
Use the appropriate operating system or audio device control panel to adjust the sample rates of the input and output devices to use the same settingt.
I have defined the sample rate to 44.1/16 bit in accordance with my inbuild soundcardt.
I am trying to record from LineIn.
When running on a M-Audio sound card I don't face any problems.
HP 8560W, sound card IDT/High definition audio Codec
Any suggestions?

You're sure you have set BOTH the input and output settings to 44.1 16 bit?
Which version of Windows are you running? There are a number of posts on this forum about how to fully access both the Windows Mixer and the Mixer for your soundcard. Especially, you need to ensure that all "Windows Sounds" are turned OFF.

What's the difference between an audio INPUT and AUX object?

Can someone explain the difference between an audio INPUT and AUX object? They both seems to do pretty much the same thing ... when would you use 1 over the other?

revDave:
Suppose you're recording a guitar track and you want to add a very gentle compressor to avoid overload during the rec process. you need an audio input channel with a compressor inserted. this way, your guitar will be recorded with the compressor processed. If you use audio and midi gear and want to bounce your material, put all your midi audio in an audio input channel.This way, you don't have to use a real audio channel to record them. You can hear them, even use some plugins, and have them bounced with your audio channels.
Now, suppose you recorded three vocal channels, and want to use an equalizer. You need an aux object to send your vocal channels and use only one eq. This is very useful when you have similar materials recorded in diferent channels (2 guitars, vocals, pete/sax/bone, and so on). Send their outs to an aux object, insert the fx you want, and set the aux object's out to the main out of your project, and it's done.
I hope it helps you.

Simultaneously read more than one input and generate output

Is it possible To simultaneously read more than one input and generate outputs depending on these inputs? If this isn't possible what is the best way to go about making some sort of timed loop that will read an input, read the next input, decide whether or not to output and so on. Hope someone can help. Thanks.Message Edited by Esmith13 on 05-25-2005 01:36 PM

Hi,
You should look at the synchronized examples for analog input and output that can be found in the example finder under:
Help>>Find Examples>>Hardware Input and Output>>DAQmx>>Synchronization>>Multi-Function
These will get you started to being able to handle multiple tasks at the same time.
I hope this helps. Have a Great Day!

Audio in and Audio out - MacBook Pro

Hello!
I'm interested in purchasing a MacBook Pro mainly for music production (I'm kinda new to the whole DJing scene) and I noticed a small difference between the 13' and 15' models. The 15' model includes a separate Audio in and Audio out while the 13' has only one Audio in/out exit. Does anyone knows what's the difference between the two? What can I do with a separate Audio in and Audio out exits like in the 15' model? Is it worth paying the extra $700?
Thanks in advance!

Yes it is, the 13" is rather lacking on a lot of things, including the video card.
Mac's have optical audio in/out ports in the stereo mini ports, which produce clearly audiophile level music.
If you want to impress people, marry a 2.2 Ghz 15" or better MBP to a quality receiver and speakers with a optical Toslink adapter and cable and you'll "WOW!" them for sure. Hear the full quality of iTunes music you have been paying for and listening on crappy iPods and their cheap headphones.

And you can do a lot more with that 2.2 Ghz 15" (psst: get the anti-glare high res screen)

Digital input and digital output at the same time

Hi all
I have a PCI-6503 board. I have done 2 task that run simultaneously: the first one is port0_16 output and the second one is port2 input.
I get sometimes (not every times...this is strange...) error-200587 saying:
'Requested operation could not be performed, because the specified digital lines are either reserved or the device is not present in NI-DAQmx.
It is possible that these lines are reserved by another task, the device is being used through the Traditional NI-DAQ interface, or the device is being reset. You might also get the error if the specified resource is currently in use by LabVIEW network variables bound to the DAQ Channel, or if the DAQ Channel is being used in any OPC Client software.
If you are using these lines with another task, wait for the task to complete. If you are using the device through the Traditional NI-DAQ interface, and you want to use it with NI-DAQmx, reset (initialize) the device using the Traditional NI-DAQ interface. If you are resetting the device, wait for the reset to finish.'
In the attached VI i have recreated the basic structure of my real VI (the error is present even here of course...).
How can i do?
I want to have both digital input and digital output with the same PCI-6503 every single cycle... Is it possible?
Please help me!!!
Kind regards.
I love the smell of napalm in the morning

DIO simultaneously error.vi ‏31 KB

Hello Maverick,
Did you have any luck with the example Raven sent you?
In Raven's example, it properly passes the DAQmx task from one SubVI to another to avoid having to open the task again. These errors are likely to occur when you have multiple DAQmx calls in a VI that call the same task again without clearing the previously opened task. If at any given time you try to open a task that already is being used, you might receive an error "resource is reserved"... similar to your original example.

How can I get my audio input and output devices back? I have no sound and cannot see any of the devices in Audio MIDI Setup..??

Hi, I tried to set up a new output audio device on my mac that would have multiple outputs (iBox Twist speaker and my internal speaker) but when I went to click onto one of the iBox Twist (there were 2 options available: iBox Twist and iBox Twist Stereo), Audio MIDI Setup crashed and when I finally got that back open, I found that there were no audio input or output devices to be found. My sound is working, as when I turn on my iMac, the starting sound still plays, however the volume control in the menu bar is no longer a black colour, but grey and when I try to change the sound on my keyboard it does not change. This already happened to me once, and after 3 hours I managed to fix it very simply (switching off Mac, unplugging power cord, leaving for 15 seconds, plug power cord back in and switch Mac back on, holding Alt, Cmd, P and R keys until you hear the Starting Up sound twice) however this same technique that fixed it once before is not working this time and I am still stuck without sound. I have tried Repair Permissions, rebooting in Safe Mode, Hardware Test and checking for Software Updates. Has anyone else had this problem and managed to fix it?
Thanks in advance for any help anyone can give me!

In case anyone has had the same problem as me, I have just managed to fix this by doing the following:
Switch off Mac
Switch back on in Safe Mode (Hit power button, then hold Shift key until a loading bar appears at the bottom of the screen).
Switch off Mac again
Remove power cord and wait 15 seconds
Plug power cord back in and hold down the keys alt, cmd, p, r all at the same time until you hear Starting chime for a second time and hopefully your audio will back.

How can I use a different driver for audio input and output?

I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
What I am trying to do is:
1) Record into Logic Express using my Tascam US-122.
2) Have playback come out of my computer sound system, not the Tascam.
If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.
