problems in hearing the sound on the main window (hear it only on the Audio Sample editor) on an old ver. (5.5)

virtzberg, good news: I managed to open the project in LPX 🙂 So, from what I could see in the Environment, it's a pretty sophisticated setup. And the reason why you cannot hear any output is, this project saved all the hardware audio interface assignments for the setup you used to produce it at the time (perhaps, that's how Logic 5.5 used to work). In other words, Logic (Pro 9, in your case) does not see the audio engine for audio signal output. Sample Editor just works with individual samples and previews audio using the default interface, I suppose. So the solution is quite straightforward, you have to reassign all the audio track objects to Core Audio.

So, right after you open the project, you'll have to go to the Environment and select Audio layer. Then if you click on one of the audio track objects and select the Channel setting in its object parameter box, you'll see that (ASIO) audio engine is ticked:

So in order to fix that, delete the channel splitter object (you may move other objects in Audio layer out of the way too), then select all the audio track objects at once, and with them all selected, go to "Channel" setting in the parameter box and choose Core Audio (make sure to note the volume fader settings for each track, because they will be reset; you may use the screenshot above for reference):

After you switch these objects to Core Audio, you'll be able to create an Output object:

You'll be able to hear the audio tracks in your project after that. Problem solved! 🙂

Let me know if anything doesn't work as I described. I'm using Logic Pro X, but its Environment workflow shouldn't be much different from Pro 9. As for the MIDI tracks, they are all intended for external MIDI instruments, but can be easily reassigned to software instrument tracks, in case you want to remix this project in the box using plugins. So hope it helps. Cheers!

You'll have to create a channel in the Mixer and assign this channel to the Output object you created, in order to have it in the Mixer. Likewise, when you do this, you could right-click on the channel and put it into arrange. Finally, select all the channels in the Mixer that are supposed to play back audio and assign their outputs to the newly created Output. You might want to double-check the output assignment with their respective objects in the Environment, as well.

You could make a copy of that project file and try to remove the splitter objects. Create an Output object routed to Stereo Out and see if that helps.

From what I see on the screenshots, most of your tracks' output is going to "Stereo Out", except for the first audio track (AIRY L) which is going to "Out 7-8". There are four master objects assigned to four different outputs (Stereo Out, 3-4, 5-6, and 7-8) in the Environment. Besides, I can also see a channel splitter object (or two of them, maybe) in the Environment screenshot. However, there's no "Stereo Out" object.

Is it possible for you to select a channel splitter object in the Environment to see where it sends the signal?

I suspect that might be the culprit. Also, when you create an Output object, which audio output is it assigned to? Is it "Stereo Out"?

Just a note, after another experiment with your project, there is actually no need to delete the Channel Splitter object, nor create an Output Object. After you collectively reassign the audio track objects to Core Audio, it works even without creating an Output object!!

From what you describe, this can indeed be fixed in the Environment. Looks like an issue with audio signal flow to me. However, it's just guessing. With the project loaded in Logic 9, could you make screenshots of: 1) Mixer (with all channels and their inputs and outputs visible); 2) Mixer layer of the Environment, with Output object selected; 3) The Arrangement. Please, post these here. To make screenshots, press Shift+Command+4 and then select the screen area (typically they are saved to Desktop).

You're most welcome, virtzberg! That's not much of a bother, really. What I can suggest at this point is for you to upload this project with all its assets (if possible) somewhere to Dropbox or Google Drive, so that I could tweak the Environment on my side using Logic Pro X. It's in fact would be interesting to see whether it's possible to restore it. If you don't mind of course.

Could you provide an email address? I can send you the link to the converted (and working) LPX project 🙂

Basically, in Logic X, you need to manually locate all the audio files referenced in the project. There are not that many, thankfully. As for the audio tracks being greyed out, it's very easy to fix: just right-click on any track header, then go to Track Header Components > On/Off (this toggles On/Off button display for tracks in LPX). For some reason these tracks are turned off. Just turn them back on and you're in business.

By the way, after analyzing the Environment of this project, I'm quite amazed at how complex your MIDI setup was! Did you automate the volume using an external control surface? Obviously, it was all made using hardware synths, samplers, and drum-machines. I guess this must be unheard of these days when everything is done "in the box".
