LIBRARY
LIBRARY puts most of the engines on one key. PRESETS walks all their factory sounds as a single list, with no trip to the wheel.
walks most engines on one key
- Half
- SOUND
- Reach it
- a custom build, FELUCCA_LIBRARY=1 (else on SHOCK)
- ALGORITHM
- the engine's first EDIT knob
- Engine
- ANALOG
- Factory sounds
- 12

LIBRARY is on the sidelines: SQRL-1's build leaves it out, and SHOCK has its key, E4. A custom build with FELUCCA_LIBRARY=1 brings it back, picked on the PAIR page (hold HOME, tap GLO, KNOB 1).
Playing it
Each step of PRESETS loads the next factory sound, and the engine changes when the list crosses into the next engine's sounds. The list wraps round at the end. Hold GLO and turn PRESETS to jump a whole engine at a time, landing on its first sound. Your saved sounds are not in this list: PRESETS walks them under an engine's own SOUND.
The pages follow the engine that is playing. MAIN shows that engine's own four knobs, EDIT walks its pages, and ALGORITHM turns its first parameter. The tables below show LIBRARY as it starts, on ANALOG; the page for each engine has the rest.
The keys play notes. The screen shows the engine's picture where it has one, and the seed-of-life pattern where it does not.

Where it comes from
LIBRARY is part of the shell, firmware/src/shell.c (CH_ENGINES lists the engines in the order PRESETS walks them). The engines are Felucca's and databurn's; their pages credit each one.
