Logic 9 Why no sound on track?

    Sorry, but this has kept me busy for so long and I still can't figure it out. I have some short audio.aif regions that don't have sound output when they are in the track but do have sound output in sample editor. I bounced one in place to see if that would help but it erased the waveform completely. Any takers?

    Stray automation??

    Don't mean to be a wise-acher (although that's happened maybe once or twice..;)) but are the audio files on an audio track and not an instrument track?

    If you right-click on the Track header, what output is the track assigned to?
    Do you see an output assignment in the channel strip?

    Is the channel strip muted? Check both the mixer and the track header in the Arrange window.

    Do these audio files playback in C5.5?

    Thanks Eli, good idea but not this time, I have used only MIDI until now in Logic and will just have to figure out what audio needs to be used. CSeye, Thank you too, very good suggestions but it is an audio track and the output is Stereo 1-2; there was a warning that no input was chosen but since I imported them from audacity in aiff I don't see what I should stick in the input slot. There are no mutes on anything. I just am not use to using Logic foe what it has been designed to do: mix audio files to make contemporary popular music. I did try Flex time first and it caused the audio to pop and crackle, so I re-imported the same sample and Bounced it in place and that worked. Now I feel the regions are to short, and was re-importing a longer bit from the Audacity file, I think I will try adding long reverb to these regions[they are all the same content-a choir shouting "NO"] without any real tempo other than the tempo of the song, there are no percussion or other strong transients to line up but after the mistake with flex time I am re reading the manuals to see if I can find something so obvious to you and other Pros that you don't bother mentioning it, such as -is aif better than caf,I found many Logic pro help discussions by googling that indicated aif was the best format for this. I have not got C5.5 set up because I use all my free time reading Logic manuals and a visitor once told me he had both but found Logic far better. Thanks again to you both.

    Hmmm, the mystery deepens. Do you have the correct audio driver set in your audio hardware drivers prefs? You probably do if you are hearing it in the sample editor.

    If the correct audio hardware is set correct, check this: Go to your mixer layer in the Environment. Select the "Stereo 1-2" channel strip you referred to in your last post. Look in the Inspector in the Environment window. And confirm that the object is indeed assigned to the stereo output 1-2 of your Edirol box. Just because it is called "Stereo 1-2' does not necessarily mean that is what it is assigned to.

    Thanks Eli, good idea, the surprise to me was that there are 2 stereo output 1-2 channel strips in the separate Environment mixer window but in the mixer under the Arrange there is only one. All are set to Stereo 1-2 output. Shall I delete one of the two in the Environment Mixer and see if that doubling was the problem? I have found that the very last copy on the track still has its' sound output so I replaced the silent ones with copies of that one and they all play back normally for the time being. I still need to study more on this but there are things in Logic that are just not covered in the Manual, for example,I googled EXS fades and got a bit from Logic Pro help where a moderator explains that the ADSR envelope 2 is the default control for all sounds passing through the EXS24,the moderator admitted this was not covered in any Manual or Book but he has used Logic since such an early version he just remembers these things-it saved me that day as I had not been able to get an easy method of forcing the GarageBand Symphony strings to play in the style I want them to use-now it is easy to do by adjusting the second ADSR envelope and it works great for getting rid of the 19 C. misconceptions about expressive playing.i.e. a very wide continuous vibrato with a steady crescendo is the norm since Von Karajan took over the Berlin Philharmonic, but source studies I did at the Royal Conservatory in the Hague prove this was not the case before 1950, and since I am almost exclusively interested in 17th and 18th C. musical styles[speaking style vs. Long line Wagner style]I sometimes have to bend the patents a bit to get what I want. And it was Wagner who popularized the unoendlichechess[neverending] melodic style that some today believe to be "natural", sorry for being such a boring pedant, but I won't be around all that much longer, thank God.

    Just a thought: Open the Empty Template (File>New>..). It's always the first one available in any of the default folders: Explore, Compose, or Production.

    Create just one audio track. Make sure the output is assigned to the main outputs of your interface.

    Open the Mixer in the Environment. Take note of what's there. A handy way to do this is to open Preview (in your Applications folder). With Preview open, navigate from the Preview File menu>Take Screen Shot>From Selection. Drag over the area of your screen that you want a screen shot of ( the Environment Mixer in this case) . Save the image to your desk top for easy reference.

    Now drag one of the problematic audio files into the Arrange window onto the previously created audio track. Once the file has loaded, go back to your Environment Mixer. Look to see what's new and different. Take another Screen Shot.

    Now drag another one of those files into an empty area of the Arrange, below the previous track. This will automatically create a new audio track for the file. Look at the Environment again.

    Dragging audio onto the Arrange area is such a basic, guaranteed-success process that should result in an audio file that plays back once fully loaded.

    Use of the Empty Template is a great way to problem-solve vs a fully loaded project.

    Word of the Day: "unoendlichechess" ;)

    I suspected something like this. My guess is that it is the result possibly of importing from garageBand, or from someone else's setup, or from an older version of Logic, etc. So yeah, just go ahead and delete one of them.

    My hunch though is that if your project has this kind of corruption, you might just be better off importing all the tracks into a new empty project - if it's not too complex (tempo changes, etc)

    Yes, this is the best way to adjust the basic ADSR parameters of the entire instrument.

    Don't know what to say David. I'm sorry to hear about your continuing health problems.....

    Thanks CSeye, I did all you asked and the only difference I can see in the 3 screenshots is that input 1 was used when there was only one empty audio track and that changed to input 1-2 after adding the audio files. I have missed something because I don't see how this will help. It may be because my empty project template seems to be corrupt, ater a long series of messages with Doug Z we finally concluded that was what was causing problems, and since then I have started all projects with a user template made from the giant orchestra template and the glitches[ interpretation turning its' self on, track header config.'s changing,etc.] all stopped. This project may have been started on that corrupt empty template and is now showing signs of corruption.
    Many thanks for the help, your suggestions in the past have been very helpful.

    Thanks Eli for the help. I had a long series of messages with Doug Z and we reached the conclusion that the empty project template in my Logic is corrupt. I may have started this song with that but in any case you are right, this file is corrupt and I need to import all to a new project based on the giant orchestra template, which I have been using as a personal template with no signs of corruption. I have done that now with all the older songs which began with the empty template and they all work nice and clean in their new clothes.
    Please don't worry about my health, everyone will die at some point, I am lucky to be in a land that still has the remains of a good universal health care cost program. The new rethuglican government here is trying to dismantle it but they have so much to do in Brussels[EU] that privatizing health care has slowed down considerably,in any case I would not be alive today if I had gotten sick while living in the USA and I feel very sorry that Americans are being ripped off by the Pharmaceutical Corporations,end of OT rant.

    Hey David,

    WRT health care, I hear you - I'm glad I live in Canada!!
