Playing it

SET on MAIN picks the instrument, or one of the user slots USR1 to USR3. CUT darkens it with a low-pass, and ATK and REL shape the start and end of each note.

The user slots are filled over USB from the editor's Samples tab (Connections; for developers, the editor protocol in web/EDITOR_PROTOCOL.md). A slot that is empty, or a set this build left out, plays a plain sine and the screen says NO SAMPLE.

SAMPLE is on the sidelines: SQRL-1's build leaves it out, and its instruments' samples with it. A custom build with FELUCCA_SAMPLE=1 brings both back, picked on the PAIR page (hold HOME, tap GLO, KNOB 1). Without it, a SAMPLE sound in a project or a saved sound plays on PHYS.

Where it comes from

firmware/src/eng_sample.c, Felucca's engine (GPL-3.0), by Leo Kuroshita, Hügelton Instruments. The instruments are from Versilian Studios' VSCO-2 Community Edition and VCSL, CC0 1.0 (assets/samples-cc0/ATTRIBUTION.txt), stored as IMA ADPCM, a compressed audio format that decodes cheaply.
