v1.1.3 - VideoPlayer 2x Speed Fix & Audio Device Sync

v1.1.3 — 2026-07-11

Critical Fix: VideoPlayer 2x Speed

Video playback previously ran at approximately 2x speed due to a mismatch between user-configured sample rate/buffer size and the actual audio device values. The global \gSampleRate\ and \gBufferSize\ variables were set from user preferences but never corrected when JUCE's audio device used different values.

Root Cause: \MainComponent.cpp\ only logged a warning when the actual device sample rate/buffer size differed from preferences — it did not update the global timing variables. This caused \gTime\ to advance at the wrong rate, making all time-dependent modules (including VideoPlayer) run too fast or too slow.

Fixes Applied

File	Fix
MainComponent.cpp	Sync \gSampleRate/\gBufferSize\ from actual audio device after \initialise()\
ModularSynth.cpp	Sync \mIOBufferSize\ from \gBufferSize\ every callback; use \gBufferSize\ for \elapsed\
VideoPlayerModule.cpp	Remove FloatSliderUpdated→SetPosition feedback loop that triggered seek every frame
VideoPlayerModule.cpp	Remove double-seek in SetPosition (direct call + atomic flag)
MovieClip.cpp	Fix \isFrameAvailable()\ — removed broken bounds check mixing native rate vs time_base
FFmpegReader.cpp	Fix \�v_seek_frame\ — convert samples to stream time_base via \�v_rescale_q\

Portable Build

This portable zip includes full Python 3.13 stdlib (for scripting support) and FFmpeg DLLs (for video playback).

Note

Extract and run \Syntetika.exe\ directly — no installation required.

V1.1.2 — Visual Modules & Audio Spatial

Syntetika Studio v1.1.2

Rilis ini membawa modul visual baru, spatial audio binaural, DJPlayer, rewrite PatternMatrix, dan upgrade SpatialRender.

---

🎨 Modul Visual Baru

Modul	Deskripsi
LissajousOut	XY oscilloscope buffer audio dengan FBO output, grid, scale/color/zoom
MeshInstances3D	3D OBJ viewer audio-reaktif, orbit camera, instancing, FFT analysis
TriggerWaveEffect	Efek visual beat-synced: Pulse, Glitch, Scanlines, All

🎧 Audio Spatial

• EclipSpatialRender HRTF: Binaural spatial — ITD (Woodworth-Schlosser) + ILD
• EclipSpatialSource: Sumber audio spatial dengan animasi + occlusion
• SpatialRender upgrade: SaveState/LoadState, IVisualSource FBO, occlusion processing, per-source volume, orbit invert
• SpatialDataSource: Shared data structures (SpatialSourceInfo, SpatialRoomInfo)

🎛️ DJPlayer

• Serato-style DJ player — BPM sync + CUE points
• Waveform display, click-drag scrub, scroll nudge/zoom
• Deteksi BPM otomatis (immutable)

🧩 PatternMatrix Rewrite

• 8 halaman (pages) — pattern data per slot per halaman
• 32 max slots (sebelumnya 8)
• Element grids di kanan — Rotary/Slider/Button column bands
• Save format rev 7 — global bindings, page data

🔧 Modul Lainnya

• FormantFilterEffect: 4 parallel formant bands
• LadderFilter: Classic ladder filter
• MidiChannelFilter: Per-channel MIDI filtering
• MidiPlayer: MIDI file playback
• BandLimitedOsc: Band-limited oscillator

🖼️ Infrastruktur

• IVisualSource: FBO output interface (Source → MonitorModule)
• GlShaderUtil: Shared GLSL compilation/linking + uniform caching
• tinyobjloader: OBJ 3D model loader

🐛 Bug Fix

• SpatialRender: stereo width, orbit animation XY plane + invert, thread safety
• EclipSpatialRender: std::sort, const_cast fix, mutex, per-instance clock
• PatternMatrix: 11 layout bugs
• Python stdlib bundling via SYNTETIKA_PORTABLE
• .gitmodules: missing libkeyfinder URL

Catatan: VideoPlayerModule & VideoDrumSampler akan hadir di v1.1.3 (menunggu FFmpeg 8.x compatibility fix).

v1.1.1 — HRTF Overload Hotfix & Project Cleanup

v1.1.1 — HRTF Overload Hotfix & Project Cleanup

Critical Bug Fix

• SpatialRender HRTF overload: Nested inner for (int s = 0; s < bufferSize; ++s) loop at line 255 removed — was running inside the outer per-sample loop, causing bufferSize× (256-512×) amplification into binaural output. Now uses outer s index directly, correct 1 sample per iteration.
• SpatialRender brace mismatch: Missing } for mutex scope added — build was broken after HRTF refactoring.
• Debug logging removed: HRTF debug printf (peak level per 60 callbacks) cleaned up.

Project Cleanup

• Dead code removed: VisualNodeBase.cpp/.h, CodeEditorNode.h, VisualNode.h — all unused.
• Stale artifacts deleted: build2/ (270 MB stale Ninja/Multi-Config build dir), build.log, dist/ (v1.0.0 installer), ignore/, Syntetiscope.cpp/.h.
