Implement research-based analog drum synthesis#27
Conversation
Updated TR-808 and TR-909 drum models (Kick, Snare, Hi-Hat) to match detailed DSP research. Key changes include: - Refined tuning and decay ranges. - Accurate pitch sweep behaviors (e.g., 2.5x for 808 Kick, 4.7x for 909 Kick). - Improved noise filtering (HPF/LPF) for Snares and Hi-Hats. - Implementation of the 6-oscillator square wave matrix for 808 Hi-Hats. - Centralized master-bus saturation using the research-provided formula. - Added micro-randomization (analog drift) for pitch and filters.

This PR updates the drum machine's synthesis logic to strictly follow the provided DSP research for TR-808 and TR-909 models. It replaces generic synthesis with accurate analog modeling, including specific frequency ratios, envelope curves, and non-linearities like master-bus saturation and analog drift.
