    Okay, having checked out the Lightsnake, clearly it does not have Outputs. This is an Input-only device. It also says it does not require a driver.

    This means you need to go back to Built-in for Input & Output. Otherwise you will hear nothing.

    When you've done that, go to +Logic > Preferences > Audio > Devices > Core Audio > Device:+ & see if you can select the Lightsnake. As mentioned before, it may be called +Unknown USB Device.+

    When you do this, bear in mind that *it will only work if your Lightsnake is connected at the time!* (I.e., beforehand.) And if you have other USB devices connected, that might be confusing, so disconnect any which are not definitely required.

    If you've done all this in the right order, then if the Lightsnake is ever going to work, now would be the time… so test your Recording procedure as outlined above.

Still, he certainly does deserve points, & he needs them more I do at the moment. And you've still got… +oops, not allowed to say that!+



    (Not that his advice is really wrong, of course. It's just that there are still options to explore. We can rebuild you!)


    Thank you for your generous comments.

    Is everything in Logic silenced? What happens if you play a Software Instrument or an Apple Loop? Since you are now using Built-in for monitoring, any sound from Logic will come through your Line Out or your Headphones (or Speakers). Do you hear anything from other applications, or Alert sounds?

    Plus:

    You say it's picking up the Instrument. You imply it has recorded it. If so, your trials are nearly over & success is within your grasp! Select one of the Audio Regions you have recorded, & click on +Sample Editor.+

    Do you see waveforms, or just a flat line?

    If waveforms, then all that is wrong is monitoring — easy fix.

    That's actually a good sign - when you unplugged the cable, your input reverted to the built-in microphone, and you got feedback, showing your in/out paths are functional.

    For this kind of situation, it can be helpful to install Sound Source. It's a free little utility which enables menu bar access to your inputs/outputs and in many cases, for people not using a 'proper' interface, can be very helpful, particularly for those with multiple in/out options.

    A quick review.

    • Your interface is working. You are recording guitar with it. Success!
    • In +Audio MIDI Setup,+ you have selected Built-in for Inputs & Outputs.
    • However, you can't hear anything playing in Logic.

    +Please note that we are now dealing with an entirely different question; this is no longer about your interface, which is fixed.+

    So… what might cause Logic to go all quiet?

    • Do you have the Output Volume turned up in +System Preferences > Sound?+
    • Do you hear sounds from other applications, & from alerts?
    • In Logic, do you have your Master Output set at 0dB?
    • Is the Yellow Solo button on? Is anything Soloed? (Option-click on it to check)
    • Is your Track muted? Do other Tracks with (e.g) Apple Loops on them play audibly?
    • Are the Outputs of your Tracks set to +Out 1-2,+ & are the level faders up?

    There are a couple of circumstances that can be problematic when using auto input
    monitoring with record-enabled tracks:
    • Singers cannot hear themselves while Logic Pro is in play or record mode. All they can hear is the old recording. Switch off Auto Input Monitoring in this situation.
    • The track cannot be heard, even though Logic Pro is not in record mode. Switch on Auto Input Monitoring to hear audio on the track.

    _To switch auto input monitoring on, do one of the following:_
    • Choose +Options > Audio > Auto Input Monitoring+ from the main menu bar (or use the +Toggle Auto Input Monitoring+ key command).
    • Control-click the Record button in the Transport, and turn on the +Auto Input Monitoring+ setting in the pop-up menu.

    It's back to the +Audio MIDI Setup+ for you, young person!

    You need to double-check that +while the Lightsnake is connected+ you still have Built-in selected for Input & Output.

    UNLESS what you mean is that you can hear everything apart from what you're recording. If that's the situation, the solution is even easy. Get your Software Monitoring & Auto Input Monitoring preferences sorted. I'll paste them below for your reading pleasure:

    -----

    _Using Software Monitoring_
    The Software Monitoring function allows you to monitor incoming audio through any effects plug-ins that are inserted into an armed audio channel. Audio inputs must be assigned on the record-enabled tracks for software monitoring functionality.

    The effect plug-ins are monitored but not recorded. This can be useful during a recording session. As an example: During vocal recording, many singers prefer hearing their performance with a little reverb, but the track is recorded dry (without effects).

    _To monitor a track with effect plug-ins during recording:_
    1 Turn on the +Logic Pro > Preferences > Audio > Devices > Core Audio > Software Monitoring+ option.
    +Note: No monitoring of any kind will occur if this option is switched off for the currently active audio hardware.+
    2 Insert the desired effect into the audio channel, arm the track, and start recording.
    The effect will be part of the monitor mix, but will not be recorded.

    _Auto Input Monitoring_
    If Auto Input Monitoring is switched on, you will only hear the input signal during the actual recording—before and afterwards, you’ll hear the previously recorded audio on the track, while the sequencer is running. This helps you to judge punch in and punch out points when punch recording. If Auto Input Monitoring is switched off, you will always hear the input signal. Auto Input Monitoring, when switched on, also allows you to hear the input source when Logic Pro is stopped, making it easy to set levels.

    _To switch auto input monitoring on, do one of the following:_
    • +Choose Options > Audio > Auto Input Monitoring+ from the main menu bar (or use the +Toggle Auto Input Monitoring+ key command).
    • Control-click the Record button in the Transport, and turn on the +Auto Input Monitoring+ setting in the pop-up menu.

    There are a couple of circumstances that can be problematic when using auto input monitoring with record-enabled tracks:
    • Singers cannot hear themselves while Logic Pro is in play or record mode. All they can hear is the old recording. Switch off Auto Input Monitoring in this situation.
    • The track cannot be heard, even though Logic Pro is not in record mode. Switch on Auto Input Monitoring to hear audio on the track.

    I absolutely do not get this stuff: I have a Lightsnake and am having the exact same issue!

    I tried to follow this thread, but nothing seems to work and there are WAY too many dead ends in Logic. Could they make this any more confusing!!?!?!?

    When I unplug the Lightsnake, I can hear my file. When it's plugged in, no sound from Logic at ALL. (system and Garageband audio fine).

    The Lightsnake is input only. Logic 8 can only use one device at a time. If that device is an +input only+ device, of course it will not play back - it cannot play back to a NO output device.
    You have to set up an aggregate device in the Audio Midi Setup. That agg device wil use the combination of the LS inputs with the Macs' built in outputs, and create ONE (virtual) device that Logic can use.
    Logic 9 can use separate devices for in- and output. It has been one of the most prolific issues.

    How to set up an aggregate device:

    Thank you, Erik. THAT made sense, and happily Logic 9 will solve.

    Still not working, tho, so here's what I did: Aggregate device using the Lightsnake and built-in output only. DO I need to understand that 'clock master' stuff? I did check the Lightsnake to resample, and closed out of the editor.

    Then, I selected the aggregate device in Logic audio prefs, but still no sound. Also, at one point I unplugged the lightsnake and when it was plugged back in, it was not recognized as the same "unknown USB device" in the midi editor ... one was grayed out and there was a second in the list. I deleted my other aggregate device and made a new one as above.

    Thanks ... I'll keep trying. Any other clarity appreciated.
