Tutorial
The DCN corpus is collective: anyone can publish and reuse transformations, conditions, and connectors across the network. Explore the broader live corpus through the Network.
This Core Collection is a practical starter library for immediate hands-on experimentation with baseline elements. Below you can find names, exact Solidity snippets, and short descriptions.
Scope note
The current Core Collection is primarily a curated library of reusable transformations and conditions. Connector coverage is intentionally limited for now; the manifest currently includes a template-level connector entry rather than a broad canonical connector library.
template.midi.scalar_endpoints.v1
Placeholder template targeting scalars pitch,time,duration|durationv2,velocity. Connector publication phase is tracked separately from transformation/condition source curation.
Format hash: not assigned
util.identity.v1
Pass-through primitive.
return x;
