A cross-platform MIDI controller for the Line 6 POD XT Pro guitar processor.
This is a Flutter spinoff of pod-ui (by arteme), reimagined with a quasi-skeumorphic interface that mimics the actual POD hardware. While the original pod-ui takes a lean, lightweight "all-in-one-screen" approach, POD Flutter focuses on an authentic hardware-like experience with rotary knobs, LCD displays, and physical-style controls.
Control all parameters, manage patches, and sync with your POD XT Pro hardware via USB or Bluetooth MIDI.
- Complete Parameter Control: All 70+ parameters (amp, cab, effects, EQ, etc.)
- Patch Management: Browse, load, edit, and save all 128 patches
- Bulk Import: Sync entire patch library from hardware
- Real-Time Sync: Bi-directional parameter updates
- POD Hardware UI: Authentic POD appearance with rotary knobs, LCD display, LED indicators
- BLE & USB MIDI: Connect via Bluetooth or USB MIDI adapter
- Expansion Pack Support: MS, CC, FX, BX expansion models
- External IR Ready: Easily disable cab and A.I.R. to use modern impulse responses - bypassing POD's dated cab modeling for superior tones with your favorite IR loader

# Clone repository
git clone https://github.com/bhsardinha/pod_flutter.git
cd pod_flutter
# Install dependencies
flutter pub get
# Run on connected device
flutter run
# Or build release
flutter build apk # Android
flutter build ios # iOS
flutter build macos # macOS
flutter build windows # Windows-
Connect Hardware:
- Power on your POD XT Pro
- For BLE MIDI: Connect BT-MIDI adapter to POD MIDI port and ensure adapter is discoverable (check adapter manual)
- For USB MIDI: Connect USB cable directly to POD (Windows requires Line 6 drivers)
-
Launch App:
- Open POD Flutter
- Connection modal opens automatically on launch
- Select your MIDI device from the list
- Tap "Connect"
-
Load Patches (Optional):
- Tap "Import All Patches" to sync entire patch library (~6 seconds)
- Or just use edit buffer (current patch loads automatically)
-
Start Playing:
- Turn knobs to adjust parameters
- Tap effect buttons to enable/disable effects
- Use patch browser to load different patches
- Save changes to hardware via patch list modal
The main screen mimics the POD XT Pro hardware interface with authentic rotary knobs, LCD displays, and LED indicators.
- Rotary Knobs: Drag vertically to adjust value
- Effect Buttons: Tap to toggle on/off, long-press/right-click to edit parameters
- Patch Browser: Tap patch name to open 128-patch browser
- Tap Tempo: Tap button to set tempo
- Settings: Amp name display mode, UI preferences
Tap the amp name to open amp selector:
- List View or Grid View (toggle in top-right)
- Filter by Pack: All, Stock, MS, CC, BX
- Display Modes: Factory names, Real amp names, or Both
- Load Options: Load with defaults or preserve current settings
Tap any effect button to open effect editor:
- Model Selection: Choose from available models
- Dynamic Parameters: Knobs change based on selected model
- Tempo Sync: Enable tempo sync for Mod/Delay (note divisions)
- Enable/Bypass: Toggle effect on/off
Tap patch name to open patch browser:
- Browse: All 128 patches organized by bank (A/B/C/D)
- Load: Tap patch to load to edit buffer
- Save: Long-press patch to save current edit buffer
- Modified Indicator: Shows which patches have been edited
The POD XT Pro's cab modeling is limited by 2026 standards. For modern, studio-quality tones:
- Disable Cab: Left-click the cab button to toggle cab on/off
- Disable A.I.R.: Open Settings menu → toggle "A.I.R. Disable" on
- Route Audio:
- Option A: POD output → IR loader plugin in DAW
- Option B: POD FX loop → hardware IR loader → return to POD (requires line-level compatible IR loader - POD XT Pro FX loop is line level, not high-Z pedal level)
- Enjoy: Keep POD's excellent high-gain amp models, replace dated cabs with modern IRs
This workflow lets you leverage POD's strengths (amp modeling) while bypassing its weaknesses (cab simulation).
Comprehensive documentation is available in the /docs/ folder:
- ARCHITECTURE.md - System design, layers, data flow
- PROTOCOL.md - MIDI protocol reference
- FEATURES.md - Feature list, limitations, roadmap
- POD_XT_PRO_DIFFERENCES.md - POD XT Pro specifics
- CLAUDE.md - Developer guide (for Claude Code)
- Bulk Import Speed: Takes ~6.4 seconds to import all 128 patches (hardware limitation)
- No Bulk Dump: POD XT Pro doesn't support bulk dump; must request patches individually
- Response Delays: Hardware requires 50ms delay between patch requests
- No Patch Caching: Patches must be re-imported on each app launch (not needed if just control is intended)
- Landscape Only: Portrait mode not supported (planned feature)
See FEATURES.md for complete list.
- CRITICAL: Verify you're using POD XT Pro (NOT POD XT or other model)
- This app is specifically for POD XT Pro and won't work correctly with other models
- CRITICAL: Verify device is POD XT Pro (160-byte patches)
- POD XT (non-Pro) uses 152-byte patches and is NOT compatible (needs a different implementation)
See PROTOCOL.md for more troubleshooting.

This entire codebase was developed using Claude Code - Anthropic's AI-powered coding assistant. From architecture design to protocol implementation to UI development, every line of code was collaboratively written through natural language conversation with Claude.
This project demonstrates the power of AI-assisted development for complex, specialized domains like reverse-engineered hardware protocols.
POD Flutter is a spinoff of pod-ui by arteme - a Rust/GTK desktop application for POD XT/XT Pro.
While pod-ui takes a lean, lightweight "all-in-one-screen" approach, POD Flutter reimagines the interface with a quasi-skeumorphic design that closely mimics the physical hardware. Both projects share the same protocol implementation knowledge, but offer different user experience philosophies:
- pod-ui: Efficient, minimalist, all controls visible at once
- POD Flutter: Hardware-authentic, with rotary knobs, LCD screens, and physical-style navigation
The pod-ui project was essential for understanding POD XT Pro's MIDI protocol quirks and behavior.
- flutter_midi_command - BLE/USB MIDI support
- shared_preferences - Settings persistence
- Doto - LCD displays
- OPTICopperplate - UI labels
