OpenMID

OpenMID is a name used in music technology to refer to several independent projects and initiatives related to MIDI (Musical Instrument Digital Interface). There is no single, unified project officially branded as OpenMID with a canonical scope, and references to the term can denote different efforts in various contexts.

In general, projects calling themselves OpenMID aim to improve openness and interoperability around MIDI. Common themes include developing open-source software libraries for handling MIDI data, enabling easier input/output, sequencing, or mapping in applications; and creating or consolidating open data resources such as instrument definitions, patch mappings, or event catalogs that help unify cross-device compatibility. Licensing and scope vary by project, but many such efforts adopt permissive or permissively licensed terms to encourage broad use and contribution.

Because OpenMID has been used by multiple, independent initiatives, users should verify the specific project’s goals, status, and licensing before reuse. Details such as programming language, platform support, and the extent of MIDI coverage can differ significantly between implementations bearing the name.
