452Logic Pro Instruments
A sampler instrument file is created in the Sampler Instruments folder.
3. The raw samples associated with the sampler instrument are placed automatically in a
folder named after their original format in ~/Music/Audio Music Apps.
4. To use the added instrument, choose it from the format submenu in the Settings pop-up
menu.
SoundFont2 files can contain multiple sounds, stored in “banks,” in addition to single-
instrument files.
When you load a SoundFont2 bank into Sampler, it creates a bank folder (.bk) and a
Samples folder, named after the SoundFont2 bank file. The .bk suffix is appended to each
folder name. A sampler instrument file is automatically created for all sounds in the bank
and is placed in the new bank folder.
The Settings pop-up menu automatically updates to reflect the new folder hierarchy. All
samples associated with the bank are automatically added to a Samples folder inside
the SoundFont folder. For example, if you load a SoundFont2 bank file named Vintage
Drums, which contains dozens of individual drum kits from several different vintage drum
machines, into Sampler, the following happens:
• A new folder named Vintage Drums.bk is created in the ~/Music/Audio Music Apps/
Sampler Instruments/E-MU folder.
• A second folder named Vintage Drums.sf2.Samples is created in the ~/Music/Audio
Music Apps/SoundFont Samples folder.
• The Settings pop-up menu hierarchy is updated and the original Vintage Drums entry
is replaced with a Vintage Drums.bk entry. This new entry is a folder that contains the
individual sampler instruments, which can be selected and loaded as usual.
Sampler memory management
Multigigabyte sample libraries are commonplace today, delivering incredibly detailed and
accurate instrument sounds. In many cases, these sample libraries are too large to fit into
your computer random-access memory (RAM). To use these huge sampler instruments,
Sampler can use a portion of your hard drive as virtual memory. When you turn on Sampler
virtual memory, only the initial attacks of audio samples are loaded into the computer RAM;
the rest of the sample is streamed in real-time from the hard drive.
Logic Pro automatically addresses all available system memory. The amount of RAM
available for use by Sampler is determined by several factors, including:
• The amount of physical RAM installed in your computer.
• How much RAM other open applications and the operating system are using.
• How much RAM Logic Pro is using. This varies in accordance with the number and size
of audio files in the project, and other plug-ins used. Sample playback instrument plug-
ins not made by Apple can significantly affect the amount of RAM that Logic Pro uses.
