Properties
Signal chain (per channel): Input → Band-Limit (HP at Source/4, 24 dB/oct LP at Source) → Zero-Crossing Tracker with Hysteresis → Flip-Flop Dividers (÷2, ÷4) × Band Envelope → 24 dB/oct Low-Pass → Sub Level + Original × Mix → Output Gain → Output. The sub follows the pitch of the played note and its level follows the bass band's dynamics; silence or no bass in the band produces no sub. Zero latency.
