SampleStack

SampleStack is a native macOS application designed to simplify the management of audio sample libraries for hardware samplers and Eurorack modules. It helps music producers and modular synth users organize, validate, and convert audio files to meet the specific requirements of supported devices, such as Make Noise Morphagene, Squid Salmple, Elektron Digitakt, and over 30 others. The tool appears to work entirely offline and emphasizes speed and privacy, processing files locally without needing an internet connection.

The application automatically detects a user's library structure and validates each sample against the target module's specifications—checking sample rate, bit depth, number of channels, and filename conventions. Color-coded badges indicate whether a sample is ready, needs conversion, or has issues. Built-in audio editing features allow non-destructive previewing, adding splice markers, detecting transients, applying fades, splitting, and cropping; changes are staged until the user saves or discards them.

SampleStack also offers batch conversion of sample rate, bit depth, and channel configuration to match any module's requirements. Users can tag, rate, and search samples using metadata, and drag samples from a master library into module-specific collections. The tool exports the correct folder layout directly to an SD card. While the listing describes SampleStack as free, the website indicates a free 7-day trial; the exact long-term pricing model should be verified on the product's current pricing page.
