Sep 1, 2025September 2025 performance summary for titanicsend/LXStudio-TE focused on delivering key user-facing features, reinforcing live-automation reliability, and tightening code quality. Major features rolled out this month improved operator workflows and visual feedback, while targeted refactors reduced risks and prepared the codebase for future enhancements. Key features delivered: - APC40 mkII Presets Browsing and UI Enhancements: Shift-based presets browsing, preservation of knob states while navigating presets, and improved UI feedback when presets are unavailable. - Lights Off Alarm: Auto-lower master fader to zero within a defined duration during a time window, with an optional warning dialog for manual fader changes and a read-only status indicator for visibility. - MiniLab3 Fader Mode: Added Fader Mode configuration for MiniLab3 with LXMidiParameterControl integration to better map fader inputs to targets for precise control. - Code Cleanup and Refactor: Improved internal names and type usage, including fixing generic usage for Offair parameter in TECommonControls and renaming modelIndexTextureHandle to modelNeighborhoodTextureHandle for clarity. Major bugs fixed and maintainability improvements: - Resolved type-safety and clarity issues in Offair parameter handling and texture naming, reducing potential runtime errors and simplifying future maintenance. Overall impact and accomplishments: - Enhanced live performance reliability and user experience with responsive controls and clear UI feedback. - Strengthened code quality and maintainability, enabling faster iteration and safer feature rollouts. - Established foundational work for future features and integrations with MIDI controllers and dynamic presets. Technologies/skills demonstrated: - Real-time control integration (APC40, MiniLab3) and dynamic UI feedback. - MIDI parameter mapping via LXMidiParameterControl. - Code cleanliness, refactoring, and type-safety improvements with clearer naming and parameter handling. Top 3-5 achievements: 1) APC40 mkII presets browsing enabled with Shift+Knob navigation and UI indicators (#758, #778). 2) Lights Off Alarm implemented with automatic master fader lowering, warning on manual changes, and status indicator (#777, #782). 3) MiniLab3 Fader Mode configured with LXMidiParameterControl integration (#766). 4) Core refactors completed: Offair parameter generic type fix and texture handle renaming to improve clarity (#781, #773). 5) Overall stability, performance, and maintainability improvements across TECommonControls and related modules.

Aug 1, 2025August 2025 delivered GPU-path enhancements, library updates, and architecture improvements that boost performance, reliability, and user experience. Notable features include Cue/Aux previews in GPU mode and updated Chromatik mixer interface, Off Air Parameters, and AutoSave for user presets. Architecture refactors to a Slot-based GlobalEffect system and improved slot notifications reduce startup risk and simplify effect lifecycles. CPU-mode shader improvements with more informative error messages, plus UI refinements (custom color parameter UI in performance mode) and targeted code hygiene work (Spotless) to reduce review cycles. These efforts collectively enable faster iteration, greater stability, and broader creative capabilities for LXStudio-TE.
