Architecture Overview

Execution Model

Voice-based polyphonic synthesis (up to 512 voices)
Control rate: 1500 Hz (32 frames @ 48kHz)
Sample rate: 48 kHz
Per-voice DSP pipeline with stages in series

Signal Flow

Voice -> Layer -> Algorithm (multi-stage)
  -> DspStage 0 [Block0, Block1, ...] -> DspStage 1 -> ... -> OutputBus
    -> Insert Effects -> Master EQ -> Audio Device

Core Classes

synth — main engine, voice allocation, output buses
Layer — runtime voice instance, holds DSP state
LayerData — voice config (algorithm, controllers, keymap, pitch)
Alg / AlgData — algorithm container (up to 16 stages)
DspStage / DspStageData — stack of up to 32 DSP blocks
DspBlock / DspBlockData — individual DSP unit (abstract base)

Program/Bank Structure

BankData
+-- programs (int -> ProgramData)
+-- keymaps (int -> KeyMapData)
+-- multisamples (int -> MultiSampleData)

ProgramData
+-- name, tags, monophonic, portamento

    +-- LayerData
        +-- _algdata (DSP algorithm)
        +-- _ctrlBlock (controllers)
        +-- _kmpBlock (keymap for samples)
        +-- loKey/hiKey, loVel/hiVel (range)
        +-- output bus routing

Oscillator Types

SINE, SAW, SQUARE (band-limited with PolyBLEP)

TX81Z FM operators (4-op Yamaha emulation)
CZ1 phase distortion

Filter Types

TrapSVF — state variable (LPF/HPF/BPF/Notch, trap-rule)
BiQuad — 2nd-order IIR
OnePoleLoPass / OnePoleHiPass — 1st order
ParaOne — parametric EQ with shelving
DSP blocks: LP2RES, LOPAS2, LPGATE, BANDPASS_FILT, NOTCH_FILT, etc.

Envelope Types

RateLevelEnvData — ADSR-style with segment times/levels
AsrData — Attack-Sustain-Release
YmEnvData — Yamaha: AR/D1/S/D2
TX81ZEnvData — TX81Z with polynomial rate scaling

Modulation System

DspParamData
+-- _coarse (base value)
+-- _fine (fine tuning)
+-- _keyTrack (keyboard follow)
+-- _velTrack (velocity follow)
+-- _mods (BlockModulationData)
    +-- _src1 (primary: LFO, envelope, etc.)

Custom evaluators: pitch, frequency, amplitude, or lambda-based.

Key On/Off

synth::keyOn(note, vel, program, keyonmods)
  -> Layer::keyOn(note, vel, layerdata, outputbus)
    -> Alg::keyOn() -> all DspBlocks, Controllers

How to Answer

For DSP blocks: check dspblocks.h for base class, alg_*.h for specific types
For modulation: read modulation.h for routing, controller.h for LFO/envelope sources
For sample playback: read sampler.h for KeyMapData, MultiSampleData, SampleOscillator
For program structure: read synthdata.h for BankData/ProgramData hierarchy

coordinator

tweakoz/orkid

Orchestrate multi-agent engine work on orkid — decomposing milestone specs into lanes, assigning machines/branches, briefing implementer and gate-runner subagents, reviewing, adjudicating gates, and integrating. Use when coordinating subagent-based implementation of a spec/milestone rather than implementing directly.

hypersyn

tweakoz/orkid

How to author procedural content in orkid using HyperSyn (Reality Synthesizer) — a Python-as-DSL system for composing particle systems, 2D/3D procedural textures, mesh/SDF operations, and (eventually) audio/sequencer graphs into compact runtime experiences. Use when the user asks about HyperSyn, ptex2d, ptex3d, hypermesh, dataflow DSL, FXV2 codegen from dataflow, subprocess graph validation, or the hypergraph composition layer.

obtnet-node

tweakoz/orkid

Operate THIS machine as an obtnet fleet node — launching the node daemon correctly, what the controller may do to this machine (jobs, builds into the staging, checkout gitsync/sync), node-side etiquette and troubleshooting. Use when setting up, running, or debugging the node side of the fleet (the controller-side skill is `obtnet`).

obtnet

tweakoz/orkid

Drive the obtnet fleet (distributed build/run/sync across machines) via obt.net.py — node routing, async jobs, artifact fetch, git-free tree sync. Use whenever work should run on another machine or files must move between machines without git.

obt-build

tweakoz/orkid

Answer questions about orkid's OBT build system, ork.build.py, CMake structure, module layout, ork.python environment, staging directories, pyext builds, and environment variables. Use when the user asks about building, compiling, CMake, or project structure.
