Test build 28: 2.5-b28 — DX7 voices play as the patch is

DX7 voices play as the patch is, as upstream SLOOP plays a DX7 cartridge voice (its editor's cartridge presets: every value at its default, 'the patch plays as it is') and as M-VAVE's firmware plays its own: dry, no level trim. Build 26's per-voice level matching is removed: upstream's method judges a sound by its name (PIANO: short chords, PAD: held chords), which fits its own labelled sounds but not a cart — PIANO 6 swells like a pad, got +11.5 dB and played 10 dB over SYN PAD 5 on single notes. Kept: the names in banks 5–12 (25), KEY VELOCITY (default 100) and dry picks (27).

Safe over builds 19–27: nothing is erased, no bank needs reloading. Going to plain upstream and back can erase banks 1–8 — save a backup in the editor first. Not a SLOOP release.
