iO-808 auto-persists progress across sessions while an explicit JSON save/load is used for sharing patterns

iO-808 persists the full sequencer state automatically, so closing and reopening the page restores all programmed patterns without any deliberate save. For deliberate sharing, the Save button downloads a .json file containing the complete pattern collection; the Load button imports such a file into another instance. This workflow separates in-session continuity (automatic) from cross-device or cross-session collaboration (explicit export) — you never need to save to keep working, but you must save to hand a pattern set to someone else.

Examples

Program a beat, close the tab, reopen it: progress is intact (auto-save). To hand it off, click Save to download the .json, send it to a collaborator, who clicks Load and selects the file.

Assessment

Explain the difference between iO-808’s auto-save and explicit save. Why might a producer want to use the explicit JSON export even if progress is auto-persisted?
