Module Reference
Bus Channel Strip contains seven reorderable slot modules plus a pinned master-end “polish coat” (Sheen). Each module:
- Has an individual bypass switch
- Is fully automatable (VST3 and CLAP)
- Can be reordered via native drag-and-drop with live drop-position preview (slot modules only — Sheen is pinned at the master end)
- Runs on a lock-free, allocation-free audio thread

This default order reflects a classic mastering/bus processing workflow:
- Corrective EQ (API5500) — address tonal imbalances before compression
- Glue compression (ButterComp2) — unify elements dynamically
- Tonal shaping (Pultec) — add character after dynamics are controlled
- Frequency-dependent dynamics (Dynamic EQ) — surgical per-band control
- Harmonic coloration (Transformer) — analog warmth and character
- Stereo widening (Haas) — spatial placement before the final ceiling
- Peak limiting (Punch) — transparent ceiling catches any widener-induced peaks
- Polish coat (Sheen, pinned) — research-grounded five-stage default-on tonality applied to the master end. Hidden behind the brushed-brass brand plate.
