Preparing samples for the Sample Drum

The Erica Synths Sample Drum plays 16-bit mono WAV, normally at 48 kHz (22 kHz is accepted for lo-fi), from a FAT32 card across its two slicing channels. Stereo files load their left channel by default when you load a folder, so fold to mono deliberately rather than leaving it to chance.

Screen space is tight, so keep filenames short and free of spaces to read them comfortably on the module. SampleStack converts a library to 16-bit 48 kHz mono, folds stereo the way you choose, and tidies filenames before they reach the card.
