Procedural Drum Synthesis Refinement & Drum Party Logic#126
Conversation
- Implement 15-bit LFSR noise utility for authentic TR-909 textures. - Refine TR-808 Kick with two-stage amplitude damping per DSP research. - Update TR-909 Snare to use LFSR noise for its "Snappy" component. - Add `randomizeDrums` feature for musical Euclidean pattern generation. - Implement "Dice" button in Drums UI with Telegram haptic feedback. - Ensure sample-accurate scheduling and proper node disposal across all drum modules. - Resolve oscillator cutoff issues in 808 Kick.

When the dice picks a non-zero rotate here, playback and the visualizer apply it via rotateArray(...) in SequencerLoop/DrumsView, but handleExport in src/App.tsx still exports plain bjorklund(...) patterns without rotation. After randomizing hats/open hats/cowbell, the MIDI export can therefore differ from the groove the user just heard; either avoid randomizing rotate or apply the same rotation when preparing export patterns.
