This release is JS-only, with pre-compressed JS files. Use state.mjs if you only need the processing core, and basic.mjs if a basis for building new visualizers is needed. If you need to target legacy browsers, choose the files starting with xp_.

Documentation is slowly being done.

Changes

Octavia

• Removed support for KORG KROSS 2 BMT1 RxCh toggle bit as it induces unexpected behaviour. Thanks @JayB1988
• drumMsb is removed entirely, and sections requiring it have all been rewritten.

Fixes

Octavia

• In XG, GS, MT-32, Motif ES and S90 ES mode, only coarse tune and fine tune RPN commits emit pitch change events. Thanks @ValleyBell, @JayB1988
• Drum first write debug messages are now fixed.
