Part II — Building Sound

The blocks you patch together, the effects bus, the parameter model, and the file format.

Node Reference — every node type, its parameters, ranges and live status
Oscillator — multi-waveform, LDF-BLEP anti-aliasing, linear FM
Filter (TPT-SVF) — zero-delay-feedback state-variable; LP/BP/HP/Notch
Envelope (ADSR) — 5-stage, 4 curve shapes, click-free release
LFO — sub-audio modulator; tempo-syncable
VCA — Q16.16 gain, EMA convergence, optional tanh saturation
Panner — constant-power stereo, EMA smoothing
Mixer — multi-input summing bus, per-input gain/mute
Exciter — entropy tap: colored noise, particle dust, S&H
Oversamplers — polyphase 1x<->2x half-band FIR
GFX effect nodes — the six master-domain effects (delay/gain/env/APF/FDN/mod)
Master Bus — final stereo accumulator — inactive placeholder
ROM Reader — flash wavetable reader — inactive placeholder
Feedback — explicit z-1 delay line — inactive placeholder
Macro Delay — block-length delay — inactive placeholder
FDN (legacy) — per-voice FDN slot — superseded by GFX_FDN
Effects & the Global EFX Bus — master-domain processing and the GFX family (delay, gain, env, APF, FDN, mod)
Parameters, Ranges & Values — the 14-bit CV convention, the base-vs-modulation model, the ID index
Patch Management (.gvp) — the JSON patch format, routing semantics, the factory example library
