Procedural Drum Synthesis Research Implementation#112
Conversation
- Implemented 15-bit LFSR noise generator in `DrumUtils` for authentic TR-909 textures. - Refactored TR-808 Kick with two-stage frequency and amplitude envelopes to emulate diode damping and the classic 'tonk'. - Re-implemented TR-909 Kick using triangle core with saturation and dual click layers (HPF noise + square pulse). - Refactored TR-808 Snare with dual sine oscillators (238Hz/476Hz) and Butterworth-filtered noise. - Improved resource management and polyphony across all drum models using `activeVoices` tracking and explicit cleanup. - Added safety guards for exponential ramps and early exits for zero velocity triggers. - Implemented bulk parameter synchronization between the application store and the audio engine. - Added a 'Techno Randomize' feature with haptic feedback to the Drums UI.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

This PR implements a full procedural drum synthesis engine based on the provided DSP research for TR-808 and TR-909 instruments. It replaces basic white noise with 15-bit LFSR noise, introduces complex non-linear envelopes for kicks and snares, and ensures robust resource management for high-performance usage in Telegram Mini Apps. Additionally, it adds a techno-optimized randomization feature to the UI.
