Build 14 — VP4 beta, 160 knob fixes
Big jump. You're coming from build 12 — this is everything since 2026-07-27, in one build. New • VP4 editing enters beta. Knobs, bypass, scenes, channels, and a Quick Build palette with drag-to-slot. All 25 effects mapped. Every write is verified by read-back — if the unit doesn't confirm a change, the app tells you instead of pretending it stuck. • Save As for presets, behind an explicit confirmation. • Preset browser rebuilt: 4-column layout, quick-jump, color tools. • Value-entry modal has a Set button now. Type a value, hit Set. Tapping outside cancels — it no longer commits. Same for the Tempo sheet. • Runs on more iPads: deployment floor lowered to iOS 17, adding the 2017–18 models. • Device selector on the greeting screen for multi-unit rigs. Fixed • 160 wrong knob tapers — 63 on the II, 97 on the III. The pointer, the readout, and the value on the wire now agree. Fitted against the units' own display strings, zero free parameters. • Cab block: Scene Ignore is back; the phantom "Preamp Enable" is gone. Dyna-Cab layout, mic controls, and speaker indicator corrected. • Knobs going blank on tab switch or scroll, value jumps on first touch, and the invisible keyboard in the value-entry modal. • II XL: Input/Gate and Output blocks reachable, Delay tempo lock works, LFO2 controllers driven, cab favorites persist. • Crash hardening: all app state is now main-actor-locked — the mechanism behind the Catalyst crash reported 2026-07-30 is a compile error now. Changed • One knob style app-wide. 1,241 labels moved to Title Case. Delay tabs follow the II XL's own order. • Demo mode serves real data — 102 wire-captured III preset names. The invented ones are gone. What to test Turn knobs on your III or II XL and check the readout against the front panel. If you have a VP4, try the chain — and tell us what doesn't stick. There was no build 13 on TestFlight — testers go from 12 straight to 14.
