--- #21 — SAFE global filters (gF).  The footgun: `djfbus` is NOT a
--- registered SuperDirt effect, and the fader CC rests at 0 → the old
--- gF1/2/3 sent an extreme value into a missing bus → sound muted with
--- no way back.  Fix: use CORE params (hpf/lpf, always available) mapped
--- so REST (fader down = 0) == BYPASS.  Untouched = no effect, ever.
--- Push a fader up → the filter sweeps in.  Cannot mute you.
+-- #21, #48 — SAFE-AT-CENTRE bidirectional DJ filters (gF).  Corrected
+-- 2026-07-27 mid-rehearsal: these three knobs (C1/C2/C3, CC49/50/51)
+-- are DJ-mixer-style filters — centre = no filtering, sweep down =
+-- low-pass closing in (subbass only), sweep up = high-pass climbing
+-- (superhigh only). The 2026-07-25 fix made rest(0)=bypass but only as
+-- two separate one-directional controls; this makes each knob its own
+-- full bidirectional sweep, safe AT THE CENTRE instead of at 0 (an
+-- untouched knob's rest position ≈ centre detent, so this is still the
+-- same "untouched = no effect, ever" guarantee from #21, just recentred).
