    Hello friends,

    I know it’s more of a DecentSampler kinda question, but as there is no official forum and is mainly used by pianobook users, I give it a go here.

    I noticed that if you move the path of your PB Samples library into another folder or rename it, you obviously have to update the library path into the preferences of DS, but the old ones remains as well.

    So in My Librairies, you have to remove one by one the previous locations as there seems to be no function to resynch it..

    Am I missing something, or is there a way I don’t know to regenerate a clean path ?
    If there is a more appropriate place to post this, let me know as well.



    On windows I see:
    SampleLibrary.db which is an sqlite file at:

    It seems to define the instruments under Browse.

    There is also:
    In the same folder that seems to define the File… menu

    Hi all,

    You are of course completely correct that SampleLibrary.db is just a Sqlite database. Unfortunately, there’s no super easy way to move an entire sample library. It’s something that’s on my (rather long) list of features to tackle. I will get to it eventually, but probably not in the next month. In theory, if you just delete the database, the plugin should rescan your local directory and recreate the database. It’s not exactly an ideal solution, I know, especially if you have stuff in the database that isn’t in your directory that you don’t want to have blown away.

    It makes sense that the issue would have to do with how deep the libraries go. I made a change recently that causes it to only look 2 directories deep. The reason for the change: it used to not be limited at all, and a handful of people had pointed their plugin at their samples drive which contained many gigs worth of data. Every time their plugin started up, it would scan their entire directory structure which took several minutes, so this was my solution to that. 🙂


    I download the archives to my Documents folder, unarchive them, and move the .zip files to a storage drive. Then play the instruments without further ado. The big commercial apps provide plenty of ado, should the need or desire for more complexity arise. DecentSampler won’t drive anyone crazy, and may in fact become a serendipity therapy tool to retrieve people from the edge. Anyone with a few fingers can enjoy playing chords and simple melodies with
    the Winter Voices, for example.

    hey again and thanks all for following-up with this,

    I should have brought a precision that I forgot. If I’m correct, there are two ‘main’ ways to load a DS instrument.
    Through FILE… (that bo din screenshot) or through BROWSE > MY LIBRARIES (which is what I used)

    I thought both where behaving the same way, but it doesn’t seem so.
    FILE… rescan and synch the library path when you change it and tell him, so it’s great and it seems to be up-to-date.

    However MY LIBRARIES doesn’t, it duplicates the instrument with the new path and keep the old one.
    I regenerated SampleLibrary.db, and even installed a fresh new update from scratch for DS, that those old paths kept being here.

    I can DELETE those duplicated instruments one by one, which I did, so it’s fine now.
    But I’m still curious to understand why does this behaves this way.



    Related library questions:
    My Decent Sampler Library folder on my PC has some problems. I’d like to understand how to fix them and prevent them.

    I have a few instruments that have duplicate names, with one of them having “(Decent Sampler)” added to the name.
    Slinky Violin is one of these.
    In that case, the latter one contains only a .dslibrary file which is 148Mb.
    The other one has a Samples file, 201Mb, and five small .dspreset files.
    It shows up in Decent Sampler only once, but it reports “Unable to open this sample library.”
    How can I fix it? How did this happen?

    In the list of instruments shown in the App’s Browser, some instruments are listed twice, and there are three “Default” entries there.
    There is one stand alone Default.dslibrary file in the PC Library folder, and one Default folder there.
    The Default folder contains several piano .aif files and a Default.preset file, and a background.png file.
    How can I fix it? How did this happen?

    The Sampler’s Browser shows two Symbria entries.
    There are no Symbria files or folders in my PC’s Decent Sampler Library folder.
    If I select one of these in the sampler it show a picture of The Synth Orchestra and offers to load it in.
    There is no folder called The Synth Orchestra on my PC and if I click to load it, it says “Unable to open this sample library.”
    If I select the other one of these in the sampler it show picture of a different keyboard, and it also won’t load.

    Aha! I just noticed that the location the Sampler is pointing to is on a different disk than the current library is.
    I had to move the Library because of space restrictions on that drive. I did point the Sampler to the new location of the Library, but there are obviously pointers in some folders back to the old drive.

    I just tried to Rescan the library, and now I have SIX default entries in the list in the sampler, and many more duplicates.

    So it seems I should probably start from scratch. Can you give me some guidance how to do that to repair the Library?

    bo din

    Delete the following two folders;


    Note: you should not keep any libraries or instruments in these folders. Ideally you have them in D or an external drive.

    If you delete the folders above, you will have a clean slate and when you launch Decent Sampler again, you will need to login and specify the location of your library folder.
    Then you can do a scan.

    If you have duplicates after this, it will be because there are duplicates in the specified folder.
    Let us know how you get on.

    bo din

    I should add that those two folders will be automatically be re-created (but clear) when you launch DS.
    And you may not have to sign in.
