SFZ Designer is a free visual tool for creating and editing SFZ sample mappings with ease. It offers a clear representation of groups, velocity layers, and round-robin samples, allowing users to manage complex sample arrangements efficiently. The interface includes draggable key ranges and velocity split points, making it simple to customize how samples respond across different keys and velocities.

The software supports all SFZ opcodes and provides assisted opcode entry with features like auto-suggestion and validation to speed up the editing process. Users can fine-tune each sample with controls for tuning, panning, and volume, while groups can also be adjusted with transpose, pan, and volume settings. Additional capabilities include cloning of groups and structures, project-level amplifier envelope controls, and global overrides at multiple levels.

Exporting is straightforward, as SFZ Designer outputs directly to the .sfz format with automatic conversion of sample paths to relative paths. This ensures compatibility and portability across different systems. Whether working on simple instruments or complex layered sounds, SFZ Designer provides a streamlined workflow to build expressive and detailed SFZ instruments.
