Quick start
How Accordiani works
Connect a MIDI keyboard, then press Enable. The app preloads the accordion samples and listens for MIDI notes in the browser.
With Bass split enabled, notes up to the split point use the selected chord mode. Notes above the split point stay as melody notes.
Use Bass and Melody in the mix section to balance accompaniment against the lead line. Master volume controls the whole instrument.
Web MIDI works best in Chrome or Edge. If permission was previously denied, reset MIDI permissions from the browser site settings.
