- VSTi track: SF_RENDER_ENGINE=bridge → native_render.render_offline (velocity float 0..1 từ midi_events MIDI 0..127), fallback oscillator khi lỗi - chorus/reverb/gain: luôn dùng scipy/numpy fallback, xóa nhánh HAS_PEDALBOARD - bỏ top-level import pedalboard (Pedalboard/Gain/Chorus/Reverb) - test mới: bridge branch fallback, FX chorus/reverb scipy
