Oct 1, 2025Month: 2025-10 — Key accomplishments: Implemented the SlicerT Quick Load feature for LMMS/lmms, enabling opening audio samples from the file browser directly into a new SlicerT instance. This was achieved by adding a context menu option to create a new instrument track, load the SlicerT plugin, and load the selected sample in a single workflow. The change is documented under commit 872426bfc961f39dd0eee561d06fdea559d5edbb. No major bugs were fixed this month. Overall impact: accelerates prototyping and improves user workflow for sample-based SlicerT usage, reducing manual steps and integration friction between the file browser and the SlicerT plugin. Technologies/skills demonstrated: LMMS plugin architecture, UI extension via context menu, file I/O integration, cross-module coordination with SlicerT plugin, and Git-based change traceability.

Jun 1, 2025June 2025 monthly summary for LMMS/lmms: Delivered a critical bug fix to the LOMM plugin that improves initialization reliability and user experience. Fixed the Init button to stop acting as a toggle; pressing it now resets parameters and does not leave the button in a pressed state, preventing unintended parameter changes during startup and plugin initialization. This targeted fix reduces configuration errors and supports smoother onboarding and usage for users developing with LOMM.
