trouble recording audio

[tuftyone]

hi,

I'm trying to record some guitar on an audio track. I'm pretty new to logic and set up my studio a few months back with a friend and got everything working; recording midi and also some test guitar ..I've been playing around with midi stuff mainly since then and just tried to record some more guitar again and it won't, although I can see nothing wrong. Its probably something simple but its a bit frustrating as i haven't changed anything (i think!).

Please help

Thank you

Hello tuftyone, and welcome to Logic Pro Help.

Can you describe what you have attempted? How is the guitar connected, what you've done in Logic etc?

Also, please add your Logic version and system info to your signature: Forum Rules - please READ THIS before posting (#5)

[tuftyone]

thanks for getting back to me so quickly, I've updated my signature as requested!

The guitar is connected through my mixing desk which then goes to my Audiophile USB sound card. All works fine when playing my guitar and it comes through the speakers just fine, just won't record for some reason. I just get a flat line in logic.

In logic, I create a new audio track, enable recording and hit record. I've even gone back to the original project that i used to test midi and audio recording with my friend and tried to add a few bars to the previously successful audio track and all i get still is the flat line now.

Does that help at all??

Thanks for your help

Is the correct input selected in the i/o section of the channel strip you're using to record?

Also a quick test: if under Preferences > Audio you disable "Software monitoring", can you still hear your guitar when playing (not recording, just playing)?

yeah check where you are monitoring from. if your monitoring direct (rather than from Logic using the Software Monitoring function) then there may be a problem with the audio getting into Logic if your audio file shows nothing. I take it you have selected your audiphile usb as the input and output device in Logic's audio preferences, same place as the software monitoring switch david described above.

[tuftyone]

i can hear the guitar whether software monitoring is enabled or disabled and the audiophile is selected as the device. also I'm not sure how i check if i/o input is correct

[Perspex People]

well sounds like your monitoring direct. that is through your interface and before the audio signal reaches Logic. I dont know your interface so I cant offer any advice there. its normally possible to turn that off in the software that came with your interface. then you could choose to monitor through logic by choosing software monitoring.

To get audio into Logic you first select the input you want to record on the channel strip your working on. so in the inspector area on the left side of Logics arrange window you should choose the input you've connected the guitar to. then you should see a recording level in the tracks meter. If you see the input level on the track (after you've record enabled the track -press the r button - it will indicate record enabled by turning red in color) then your good to go!

its to be noted though that for recording guitar normally monitoring direct offers a better result due to having no latency. software moniroting normally introduces latency (a signal delay) which could make it more difficult for the performer to record the part in time.

That means you are monitoring your guitar through your audio interface's monitoring feature, whether or not Logic is set up correctly.

The first thing I would do is go through your interface's software and make sure you can NOT hear your guitar when in Logic "software monitoring" is disabled.

Then select software monitoring in Logic, and select the correct input on an audio track (the input # where your guitar is connected on your interface), and click the track's "R" button to record enable it. If you still cannot hear the guitar, you're probably using the wrong input #, so try them all until you find your guitar.

hmm the audiophile software is pretty sparse...

The fact that I can hear my guitar by connecting it to the mixer, which is connected to the audiophile soundcard, which is then connected to an external amp and speakers implies everything is connected properly?

...and i can record midi no problems


also below I/O in the channel strip it says Input 1, Output 1-2 with no other options

No, it just means your guitar is somehow connected to your speakers, but that does not mean it's correctly connected to Logic.

That's why I suggest disabling software monitoring and making sure you can NOT hear the guitar. THEN you can set up Logic to hear your guitar, and with software monitoring off, hearing the guitar will mean the guitar is properly connected to Logic.

also below I/O in the channel strip it says Input 1, Output 1-2 with no other options

After you follow my advice above, click-hold where it says "Input 1" and try other inputs.

i found out how we got the guitar in to logic originally; by routing it via one of the aux sends in the mixer. not sure how or why that works, but it does. i've managed to record some guitar but there is a terrible lag/latency. I still want to get to the bottom of why its not properly connected to logic though. I know M-audio Audiophiles are used a lot in home recording but I haven't read anything about these particular problems.

Well, what is that aux send cabled into?

[tuftyone]

... The input jack on the rear if the audiophile. Which i guess is correct. Still the software monitoring option makes no difference disabled or enabled, I can still hear my guitar. Just recorded some more guitar and no lag this time. Weird.

so to record the guitar directly into logic you can plug the guiter into the audiopile input instead of the send from the mixer.

to use software monitoring, first switch it on, then you must then select a track and choose the input you have connected the guitar to, press record enable on the track then check you can see the level on the meter when you play. if you open the audiofile software and either mute the input the guitar is connected to or turn it down then you will be hearing only the guitar signal being processed through logic by the software monitoring function.

if you have still not managed to find the input volume within the audiophiles software and software monitoring is turned on in the situation above you could be experiencing some latency but in fact you are monitoring both the interface input at source and also the input being processed through logic. that would explain why sometimes there seems to be a delay then it goes away because your perhaps hearing this when switching software montoring on??

please try to find out how to turn down the interface input through its software then perhaps you will be more able to determine if software monitoring is working and also record into logic! which I believe is what you want to do

I'm sorry if this has already been answered, but I'm experiencing the same problem (recording a flat line), except I'm using a keyboard as a sound module, plugged into my Mbox2.

I can also hear the keyboard whether or not software monitoring is enabled.

As a complete newbie (last night was my first attempt to record myself as my other bandmate that usually does it is out of town indefinitely), when you say,

"The first thing I would do is go through your interface's software and make sure you can NOT hear your guitar when in Logic "software monitoring" is disabled."

- I'm not exactly sure how to do that with the Mbox 2 - I've tried looking it up but keep getting conflicted answers.


Any idea on how to do this with the Mbox2? Thank you!
