About Arpin

Arpin is a MIDI arpeggiator whose patterns come from Chopin's piano music. Its library holds672 figures read from 47 Chopin pieces in the Mutopia Project's openly licensed editions: every passage where one hand arpeggiates a single harmony, written down by chord role rather than by note. Hold any chord and Arpin plays it through the chosen figure with Chopin's spacing, register and rhythm. Each figure credits its piece, bar and typeset edition.

A 4×8 grid of pads holds 32 figures, loaded from banks such as Nocturnes, Études and Wide sweeps or picked from the library by work, family, rhythm and span. Legato mode keeps a figure in time across chord and pad changes and starts each new chord on its bass; restart mode begins it again on the quantise grid. Arpin follows the host's tempo, can send each hand on its own MIDI channel, and runs offline. It is rule-based and uses no generative AI.
