Part I — Architecture & Concepts

How GDVP is built: the signal model, the patch graph, and the expression layer.

Global Concepts & Signal Model — parts, voices, nodes, buses, the fixed-point world, the lock-free three-thread model
The Node Graph (DAG) — patches as directed acyclic graphs; ports, fan-in, Kahn topological compilation
Performance & Expression — voice modes (mono/legato/poly/unison/chord/arp), glide, pitch bend, MPE
