Orch Node-based DAW

Orch is a local node-based DAW with MIDI 2.0, OSC and VST3 for composers who prefer to build music from connected ideas, reusable sections, routing decisions, and node-based MIDI orchestration rather than starting from a conventional track-first timeline.

Sketch sections, variations, layers, and routing containers as a graph instead of starting with empty linear tracks:

• Graph-Based Orchestration - Sketch sections, variations, layers, and routing containers as a graph instead of starting with empty linear tracks.
• Visual VST Mixer - Patch VST3 instruments, effects, audio busses, and outputs on a routing canvas that stays with the project.
• Sample Browser - Catalog local libraries, browse instruments with artwork, build collections, and keep sample choices visible.
• Piano Roll Editing - Edit notes, velocity, quantize, legato, staccato, triplets, trimming, undo, zoom, and articulations.
• Expression Lanes - Draw CC, pitch bend, poly aftertouch, and channel aftertouch data where the musical material lives.
• MCP Agent Control - Optionally expose controlled project actions to MCP-compatible tools for assisted editing and navigation.

It is designed for composition, node-based MIDI orchestration, VST3 routing, sample-library organization, and detailed stream editing in a local desktop workflow for Windows and Mac.

A useful alternative DAW for composers who prefer structure, routing, and node-based MIDI orchestration over a conventional track-first timeline.
