A comprehensive song progress tracking tool for Rock Band 3 custom song authors using REAPER. This all-in-one ImGui-based interface streamlines the charting workflow with intelligent context switching, automatic FX window management, and visual progress tracking across all instruments and difficulties.
The tracker organizes your work into logical tabs:
- Setup - Configuration and Practice Section (PRC) event insertion tool
- Drums - Track progress for PART DRUMS
- Bass - Track progress for PART BASS
- Guitar - Track progress for PART GUITAR
- Keys - Track progress for PART KEYS (with Pro Keys support)
- Vocals - Track progress for PART VOCALS and HARM1/HARM2/HARM3
- Venue - Track progress for CAMERA and LIGHTING tracks
- Overdrive - Visual overview of overdrive phrase placement across all instruments
- Automatically detects project regions and displays them as columns
- Color-coded progress cells match region colors from your project
- Three-state progress tracking per cell:
- Red - Not Started
- Yellow - In Progress
- Green - Complete
- Gray - Empty (no notes in this region for this difficulty)
- Click cells to cycle through states; right-click difficulty (or track-toggle) buttons to batch-cycle all cells
- Progress data is saved per-project and persists across sessions
Switch between difficulties with a single click:
- Expert / Hard / Medium / Easy buttons for instrument tabs
- Changing difficulty automatically:
- Updates RBN Preview FX presets to show correct note lanes
- Adjusts inline MIDI editor note row visibility via CUSTOM_NOTE_ORDER
- Updates the progress table to show completion for that difficulty
- Toggle Pro Keys mode on the Keys tab
- Tracks per-difficulty progress for PART REAL_KEYS_X/H/M/E
- Automatically opens the appropriate Pro Keys track in the MIDI editor
- Separate progress state saved independently from standard Keys
- Switch between V (Lead Vocals), H1, H2, H3 (Harmonies)
- Each harmony track has independent progress tracking
- MIDI FX toggle button to enable/disable MIDI FX on the current vocals track
- Any modifier (Ctrl/Shift/Alt) + click toggles all harmony MIDI FX at once
- Switch between Camera and Lighting tracks
- Independent progress tracking for each venue track
A unique bird's-eye view of overdrive phrase placement:
- Displays all measures of the song horizontally
- Four rows for Drums, Bass, Guitar, and Keys
- Yellow cells indicate measures with overdrive phrases
- Brightness indicates note density (adjustable via slider)
- Gray rectangles show playable notes (toggleable)
- Red cells mark invalid overdrive phrases (no notes under phrase)
- Click to place/entend/erase overdrive phrases
- Minimap scrollbar for quick navigation through long songs
- Fast-scroll when hovering over the minimap
- Align button tiles all four RBN Preview FX windows horizontally
- FX toggle button shows/hides all floating FX windows at once
- Geometry is saved and restored between sessions
- Intelligent focus management redirects keyboard focus back to MIDI editor after UI interactions
Uses REAPER screensets 1-5 for quick context switching:
- Screenset 1 - Instrument tabs (5-lane view with FX windows)
- Screenset 2 - Vocals tab layout
- Screenset 3 - Overdrive tab layout
- Screenset 4 - Venue tab layout
- Screenset 5 - Pro Keys tab layout
Save Screenset button saves the current window layout to the appropriate screenset. Screensets auto-load when switching between tab categories.
