Composer Tools Pro Directory and Memory Management

Composer Tools Pro stores presets in memory banks. Each bank can hold 256 presets. Memory Banks are standard Lemur jzlib files that can be exported/imported like any other. This makes it easy to add new memory banks if you need more presets, and export/import them to be backed up or shared.

Lemur has a finite amount of memory. Never import more memory banks than needed. Lemur will behave unpredictably if your project size exceeds the limit. Do not use memory banks to organize presets. Instead, assign preset search tags. For more information, see: Creating Presets.

Try to reuse presets. If two different sample libraries use the same settings, use the same preset for both rather than duplicating it. This saves memory and is easier to maintain.


To view and organize your presets, navigate to the directory. There you can filter presets by sample library developer and instrumental family. The directory also features the ability to multi-edit presets. For more information, see: Multi-Editing Presets
