Instruments

A growing index of bounded capabilities admitted as Fountain Coach MIDI2 instruments.

The catalogue

A field still taking shape.

Three instruments are published as organization catalog projections. Their implementation, acceptance, and release claims remain separate.

The catalogue is a boundary.

This is a published catalogue and architectural previz, not an operational marketplace. Each tile is a public projection of a Fountain Coach-owned instrument identity, MIDI2 contract, scenario lineage, risk posture, and release boundary.

The governed path

Fountain Coach identity
→ MIDI Association identity
→ MIDI2 instrument contract
→ scenario evidence
→ risk disposition
→ catalogue publication
→ optional released instrument

Fountain Coach owns implementation, evidence, risk decisions, and release authority. The MIDI Association supplies standards and identity/licensing mechanisms. Association overview · SysEx ID policy · Logo licensing
