If you are the kind of person who likes to make their own EXS24 sampler instruments, then chances are you have built up a '˜library' of these instruments over the years. And as time goes by, you will no doubt replace your battle weary Mac with a shiny new model. Another scenario that prompts the challenge that this tutorial addresses is where you need to take your sampler instrument library to another studio. In either case, you need to be aware of what files are required and where they live, in order for this operation to be a success.
The problem is of course that Logic Pro makes life so easy for us! However, many users don't realize that an EXS24 sampler instrument is comprised of both the sampler instrument file and the sample files (the recordings) themselves in order to function correctly. When you make your own, the sampler instrument file is stored in the following location:
User Home > Library > Application Support > Logic > Sampler Instruments
The location of '˜user' sampler instrument files.
The sample files can be stored anywhere however! When the instrument was created, Logic Pro created the links between one file type and the other so the sampler instrument knows where to look. Serious samplists often keep their sample file collection on an external drive, but hit a problem when moving that external drive to another Mac '" the sampler instrument files are still buried in the OS on the Mac they were made on!
So to successfully back up, move and reinstall your sampler instruments, either from an old Mac to a new one, or from one studio to another, follow these steps...
On your old Mac (and do this before you get rid of it!):
Go to User Home > Library > Application Support > Logic > Sampler Instruments and copy all the sampler instrument files to your external drive. On Lion and Mountain Lion you will need to hold down the Option button in order to access the User Library from the Finder's Go menu.
Accessing User Home > Library.
If the sample files are already on the same external drive, then all well and good, and you can proceed to '˜On your new Mac' (below).
If the sample files are in any other location (other than the external drive you are using to perform the transfer) do one of two things:
Manually backing up an EXS24 Instrument and its related sample files.
Repeat for all sample instruments sampler instruments you want to move.
This will backup both the sampler instrument and the sample files, which are put into folders named by sampler instrument.
On your new Mac:
In order for EXS24 on the new Mac to recognise the sampler instruments, the files need to be in the following location: User Home > Library > Application Support > Logic > Sampler Instruments so copy them there from the external drive.
When you open the sampler instrument in Logic Pro it should automatically find a sample files if either of these is true:
If you simply moved the sample files there after you made the instrument (and didn't manually save the Sampler instrument and sample files from within EXS24) the following dialogue will appear if any audio files exist on the hard drive of the Mac with the same name(s) as the one(s) that EXS24 is looking for:
To force EXS24 to only look on the external drive (and ignore the internal drive files) you will need to go to the EXS24 Preferences which are accessed from the Options menu on main EXS24 window (or the Edit menu of the EXS24 Instrument Editor) and make sure '˜Search samples on...' is set to '˜External Volumes' then reload the problematic sampler instrument in EXS24.
When prompted choose the correct location for the sample files and click OK.
