evanduz Posted October 13, 2013 Share Posted October 13, 2013 Before using MIDI in my compositions in LPX, I like to preview the midi to see if it is what I was looking for (they often have odd names, etc.) It used to be that Mac would allow a preview by selecting the midi file, and hitting the spacebar. If I remember correctly, it was only played with the piano sound, but it gave me a good idea of the beat/melody. For a while, but only now enough to annoy me sufficiently to write a post, the quicklook has not worked. I click it, and it looks like it is "playing" the midi, but there is no sound. The QuickLook will still preview other sounds, but not MIDI files (.mid) Any ideas? Thanks! Evan Quote Link to comment Share on other sites More sharing options...
Jordi Torres Posted October 13, 2013 Share Posted October 13, 2013 Working fine here in 10.8.5. Does it happen with any MIDI file you try to preview? J. Quote Link to comment Share on other sites More sharing options...
evanduz Posted October 20, 2013 Author Share Posted October 20, 2013 Yes, it happens with every MIDI file I try to preview. Very frustrating! Quote Link to comment Share on other sites More sharing options...
Jordi Torres Posted October 20, 2013 Share Posted October 20, 2013 If something's not messed up with Quicktime in your system, it must be something to do with the MIDI files you're trying to preview. We could see which one it is if you upload one of these MIDI files for us to test in our systems. J. Quote Link to comment Share on other sites More sharing options...
evanduz Posted October 20, 2013 Author Share Posted October 20, 2013 Lead.mid Random .mid file Sure - I am uploading one now. I have to say that it is extremely unlikely that there is anything wrong with the midi files, I have a ton of them, from many different sources. If one set were corrupt, the others won't be. Here is a random midi. It doesn't work (nor do any of the others...) Thanks! Evan Quote Link to comment Share on other sites More sharing options...
uncle808us Posted October 21, 2013 Share Posted October 21, 2013 I have had this same problem with QuickTime and quicklook for sometime now. I am using QuickTime 7 Pro and the files look like they are playing but there is no sound. This also has screwed up another DAW of mine that needs QUICKTIME instruments to play sound. I cannot find a fix anywhere and believe me I have searched. Quote Link to comment Share on other sites More sharing options...
Jordi Torres Posted October 21, 2013 Share Posted October 21, 2013 [attachment=0]Lead.mid[/attachment] Sure - I am uploading one now. I have to say that it is extremely unlikely that there is anything wrong with the midi files Thanks for uploading the file. Indeed, I agree that it's unlikely a problem with your MIDI files. In fact, I can preview this one in Quick Look just fine, so it's definitely a problem with Quick Look/Quicktime in your system (and by uncle808us's post, you're not alone). Unfortunately I don't have a solution for this...if I find out anything I'll post back. J. Quote Link to comment Share on other sites More sharing options...
Jordi Torres Posted October 21, 2013 Share Posted October 21, 2013 OK, the plug-in responsible for giving Quick Look the ability to preview audio and MIDI files is Audio.qlgenerator, which can be found in Macintosh HD/System/Library/Quick Look. The one I have is version 4.0. How about you guys? Furthermore, here's something you guys can try: If you do have a Quick Look plug-in that should be able to read your document type and you still can't create a preview of the document, or if the preview appears garbled, then it is likely that the plug-in is not loaded correctly or the Quick Look server cache is corrupted and needs to be rebuilt. First try running a permissions fix on the boot drive using Disk Utility to ensure that the Quick Look plug-ins and other files the Quick Look server needs are properly accessible, and then force Quick Look to reload the plug-ins and its cache by running the following commands in the Terminal:qlmanage -r qlmanage -r cache After this is done, clear out the Quick Look configuration files by going to the /username/Library/Preferences folder (in Lion press the Option key and select "Library" from the Finder's Go menu), and then removing the files called "com.apple.quicklook.ui.helper.plist," "com.apple.quicklookconfig.plist," and "com.apple.QuickLookDaemon.plist." With these files removed and the Quick Look service reloaded, try previewing your documents again. Source: Fixing Quick Look issues in OS X J.

uncle808us Posted October 21, 2013 Share Posted October 21, 2013 I did a search and could not find the Audio.qlgenerator any idea where I can find it? Here is the files in my library: I can't get QuickTime to play midi files either so now I'm off to search for a midi file component for QT.

Jordi Torres Posted October 21, 2013 Share Posted October 21, 2013 I did a search and could not find the Audio.qlgenerator any idea where I can find it? It's a QuickLook plug-in, so it won't be in a Quicktime folder. It should be in Macintosh HD/System/Library/QuickLook/ I can't get QuickTime to play midi files either so now I'm off to search for a midi file component for QT. I think you should first give a shot to that procedure in the article I linked. J. Quote Link to comment Share on other sites More sharing options...
uncle808us Posted October 21, 2013 Share Posted October 21, 2013 I realize It's a QuickLook plug-in I included the QuickTime view to show I have no component for QuickTime for midi as well. Sorry for the confusion. "I think you should definitely give a shot to that procedure in the article I linked." I did this and searched the listed urls for the plug in and did not find it. I am searching for : Audio.qlgenerator -- Support for audio files (MP3, M4A, WAVE, MIDI, and so on) Quote Link to comment Share on other sites More sharing options...

I did this and searched the listed urls for the plug in and did not find it. You shouldn't have to look for any third party QuickLook plug-ins to be able to preview MIDI files with QuickLook. Are you saying you don't have the Audio.qlgenerator plugin which is part of OSX (not third party)? I included the QuickTime view to show I have no component for QuickTime for midi as well. Do you mean that you cannot even play a MIDI file in Quicktime? Is that it? J. Quote Link to comment Share on other sites More sharing options...
uncle808us Posted October 21, 2013 Share Posted October 21, 2013 No I don't have the Audio.qlgenerator plugin which is part of OSX (not third party)? See list above. No midi playback in Quick view.

Jordi Torres Posted October 21, 2013 Share Posted October 21, 2013 No I don't have the Audio.qlgenerator plugin which is part of OSX (not third party)? See list above. I'm not seeing the complete path to that file so I can't tell what you're showing me unless I compare it with all QuicklLook folders in my system. No midi playback in Quick view. And I also cannot play a MIDI file in Quicktime 7 Pro. You should be able to salvage all the files you need from the 10.8.5 Combo update using Pacifist: Not sure how you ended up losing those system files... J.

You're looking in the wrong place. None of the files in your screenshot exist in Macintosh HD/System/Library/QuickLook. I have that GBQLGenerator.qlgenerator in Macintosh HD/Library/QuickLook, so I believe that's where you're looking. J. Quote Link to comment Share on other sites More sharing options...

Yes I do have it in the Macintosh HD/System/Library/QuickLook. I was looking in the wrong place so I have it but I still can't play midi files. So I will have to do something else to fix this.
