I'm trying to get back the "Grand Piano" sound on my garage band.  I don't rememer changing the sound but whenever I select it -whether it's a new track or adding to an old track- it sounds more electric and less like a "piano". 


I was thinking of uninstalling garageband and then reinstalling it.  Would this solve the problem?  or should I run the upgrade again?  is that even possible?


On my laptop the sound is fine, but on my desktop it is not.  I also don't know why when you transfer garage band files from one computer to the next, the sounds do not translate.  the computer changes it to something else. 


In any case, I really want my grand piano back.  but who knows what else is wrong and I have not yet discovered it. 


Thank you for your help,

    Have you compared the settings for the "Grand Piano" track, between your laptop and your iMac? You may have accidentally saved changes to "Grand Piano" in the "Edit" panel for the track in the "Info" panel.  Check, if the "Sound Generator" is still set to a piano sound, and if it is the same as on your laptop,  and check, if any effects have been added.

    Thank you for your response.  And things are the same between the Laptop and the IMac, but then I went a step further, to check if they had the same menu options and they do not.  I'm thinking something to do with the program, yet both versions are the same as they have both been updated.  This is the menu I get on my Laptop.

    But this is the menu I get on my desktop.

    Any other suggestions?

    This looks like a part of your instrument library may missing.

    What are the MacOS X versions on your laptop and your iMac? Is your profile signature still correct?

    Did you migrate your system from the laptop to your iMac, when you setup your iMac? And use Migration assistant? Then the jampack instruments in the instrument library may not have been copied over, as Christoph Drösser reported (Re: Why are my Jam Pack voices not showing in GB?). If that should be the case, compare the Intrument libraries on both machines and copy the complete Instrument library from your notebook to your iMac, if instruments should be missing.


    In MacOS X 10.8.5 the instruments Library is installed in

    /Library/Application Support/GarageBand/Instrument Library/

    I don't remember, if it was in the same location in MacOS X 10.6.x.

    Sorry for the late reply.

    I copied the Instrument library from Notebook to IMac, but the piano still sounds the same.  Was there something else that I was supposed to do for Garageband to access the recently copied "Instrument Library"?


    Thanks for your help, btw

    Did you reboot the system, after installing the instruments?

    And do you now see the same instrument menu on both your macs in the "edit" panel for your piano track? If yes, after setting the sound generator to "piano", have you checked, if you are now using the "grand piano" or the "Steinway piano"?  Like in my screenshot?


    Have you checked in the Trackhead, if any automation curves have been added to your piano track?

  • Duckwally Level 1 (0 points)

    Yes to all of the above.

    Actually, in the sound generator it says "missing:  grand piano".  I checked some of the other sounds too and some of them are missing.

    Look again into your Instrument Library.


    In the folder

    /Library/Application Support/GarageBand/Instrument Library/Plug-In Settings/Piano/


    you should find the following instruments:

    and you should have plenty of wav files in

    /Library/Application Support/GarageBand/Instrument Library/Sampler/Sampler Files/Grand Piano/


    also Grand Piano files in

    /Library/Application Support/GarageBand/Instrument Library/Sampler/Sampler Instruments/Grand Piano On Stage.exs

    done and it still says it's missing.  I rebooted and reloaded the program.  it still says it's missing.

    Is that what you are seeing?

    I get this, when I move the file

    /Library/Application Support/GarageBand/Instrument Library/Sampler/Sampler Instruments/Grand Piano.exs


    to the Trash.


    Check, if this file is missing or corrupted in any way. Compare the file sizes between your two macs. Maybe the protections are not the same. Compare, what you you see in the "File > Get Info" panel.

    the "missing" message was there in the beginning and I compared the file sizes etc between the two macs and everything is the same, right down to the read & write permissions.

    Then I really have no more ideas. BTW, when I remove the "Grand Piano.exs", my piano sounds more like a horn or organ, not like an instrument with strings.


    Have you installed any additional audio components on your iMac that could be interfering? Any Midi drivers, plug-ins? Check this folder for Components and plug-ins:

    mine sounds like that but with the "Grand Piano.exs" and thanks for trying.  isn't ther an uninstall button?

  • léonie Level 10 (91,154 points)

    I was thinking of uninstalling garageband and then reinstalling it.  Would this solve the problem?  or should I run the upgrade again?  is that even possible?

    What is your current MacOS X version? How to uninstall will depend on that.
