Changelog

All notable changes to this project will be documented in this file. The format is loosely based on Keep a Changelog, and the project broadly follows Semantic Versioning.

[Unreleased]

[1.0.1] - 2026-05-30

Added

  • Preset-bank import/export — "Import Bank..." / "Export Bank..." in the preset menu. Import accepts a single preset object or a JSON array of presets (written into the user-presets dir); export writes the user set as one JSON array. Lets downloadable banks be distributed after release.
  • Brand wordmark rendered in the FALLOUT olive body (position/size tunable via the brandLogo key in Resources/Layout.json / the F2 layout overlay).
  • Resources/Layout.json now ships in BinaryData, so hand-tuned pill/section positions survive in a signed/installed build (the on-disk dev file still wins when present).

Changed

  • First-run theme is now FALLOUT (was VAULT). The user's tile-strip choice still persists and is restored on every later launch.
  • FALLOUT pills are opaque (no host/desktop bleed-through; far more legible), knob mounting-shadows are smaller, softer, and directional (light from upper left), and the OUT knob gains two engraved concentric rings.
  • Standalone preset bar shows the preset name + index from launch instead of "N presets" until the user steps prev/next.
  • In the arcade quit-confirm menu, ESC now backs out; only Y/Enter exits.

Fixed

  • Intermittent light vertical seam stripes between FALLOUT rack columns at certain window scales (sub-pixel anti-aliased seams between abutting columns).

Added

  • Duck routing — Reverse-bass duck triangle now cycles Off → A → B → AB instead of being a binary toggle (pid::duckRouting replaces the legacy pid::duckVoiceA). A is the original behaviour (Voice A sub ducked by Voice B body, classic reverse-bass). B ducks Voice B body via a synthetic 25 ms trigger pulse — using subPart as the key fails because A's sub takes too long to ramp up while B's body has already faded by then. AB runs both legs simultaneously. Off is bit-identical to the pre-feature path (both per-voice duckers skipped entirely). The chain-level DUCK column (always-on tail duck on the wet bus) is unaffected by the routing — it continues to duck the reverb/delay tails as before.
  • Duck triangle UI — The letter inside the triangle now rides the hypotenuse (tl→apex diagonal) instead of being painted upright, with contrast-aware colour (dark on bright accents, bright on dark accents) so it's readable on every theme. Off state shows the full word DUCK (auto-fit to the hypotenuse); active routing shows A/B/AB. Click cycles the routing param via juce::ParameterAttachment, mirroring the DecRoutingPill pattern (which has worked for the DEC knob since 2026-05-24).
  • State migration — Old DAW projects and user-saved presets containing the legacy duck_voice_a bool are transparently translated to duck_routing=A (true) or duck_routing=Off (false) on load. The migration helper (bombo::migrateDuckVoiceAToRouting in Source/State/DuckMigration.h) is a pure ValueTree transform run inside setStateInformation before apvts.replaceState. No user action required; no broken state.
  • Factory preset Reverze 1 — User-saved reverse-bass kick added at slot 03 of the curated factory bank (existing 02–08 bumped to 03–09 then swapped slot 02↔03 so Rez stays at 02 and Reverze 1 lands at 03). Pew is now slot 09; game's shot-sound lookup is by displayName so the in-game audio is unaffected. Pew's reverb_mix=0 enforced so the in-game shot stays dry (was 0.06 before).

Build & CI

  • macOS CI build time — The universal (Apple Silicon + Intel) macOS CI build linked with LTO and ran an unbounded parallel build on a 3-core runner, so a single translation unit could take hours and a whole job ran for ~3 hours. CI now disables LTO on macOS/Linux, pins the macOS build to -j 3, and caps each job at 45 minutes so a runaway fails fast.

Fixed

  • Linux user-preset location — User presets were written to ~/.config/.config/Bombo/Presets (an accidental doubled .config). They now live at the correct ~/.config/Bombo/Presets, and any presets left at the old path are migrated automatically on first launch.
  • Cross-platform boss behaviour — The RUMBLR boss's phase-2 charge used the C library rand(), whose sequence differs per platform, making the charge cadence (and its unit test) non-portable. It now uses a seeded std::mt19937, for identical, reproducible behaviour on every platform.
  • BBS game speed (slow motion) — The v2 game ran in slow motion wherever the host can't sustain a true 60 Hz repaint — most visibly under WSLg software rendering, but any heavy-paint frame did it. The sim integrates on a fixed 1/60 timestep with no catch-up (tick() advances exactly kTickDt per call, driven by startTimer(16)), so a starved timer slows wall-clock time directly. BBSComponent::timerCallback now steps the sim by real elapsed time (a wall-clock accumulator, capped at 4 steps/callback to avoid a spiral after a hitch), so the game runs at the intended speed regardless of frame rate. tick() itself is unchanged — only how often it's called — so game logic and tests are unaffected. Regressed in the v2 rewrite (0e8ec2d scaffold → cb21815 "60 Hz fix"); v1 ran at 50 Hz.
  • Duck triangle label — Resting (Off) state shows the full word DUCK again instead of a lone D; active routing still shows A/B/AB. Text is full-strength bone (was 0.35 alpha → near-invisible) and auto-fits the hypotenuse so the longer labels don't overflow the wedge. Bold on every theme.
  • OUT hero knob indicator — The focus-ring (logo) knob's pointer was a thin bone stem that vanished into bright accent rings (magenta / neon themes). It's now contrast-aware: a wider dark-grey stem with a thin bone keyline over a bright accent, bone stem over a dark accent — legible on every theme.
  • Editor crop / scope flush — Lifted the editor so the scope's green U-frame sits flush under the host/title bar (crop top moved to the scope-strip boundary at design-y 50), removing the empty band above the scope while keeping the 3 px U-frame border from clipping to sub-pixel. Window aspect ≈ 0.586 (was ≈ 0.578).
  • Loop cache — Fixed the audible "every other hit cut" alternation in LOOP + TAIL ON mode where reverb tails alternated between full, truncated, and tonally altered every beat. Root cause: the loop cache invalidation check uses std::memcmp on ChainParams, but the struct mixes float/int/bool and the compiler inserts padding bytes between fields. Default construction (bombo::ChainParams p;) left padding uninitialized (stack garbage), so two structurally-equal instances built in different stack frames could fail memcmp on padding alone. The cache invalidated every block, forcing per-beat re-capture with a chain_.reset() between each — different live FX state per beat = audible alternation. Fix: std::memset(&p, 0, sizeof(p)) at the top of BomboProcessor::buildChainParamsFromApvts() zeroes padding deterministically; named-field assignments below override the zeroed bytes for actual values. Symptom went latent before because the exact padding pattern depended on what was on the stack, which is build/optimizer/runtime sensitive — recent commits shifted call stacks enough to expose it consistently. Bombo's existing audio-regression test ("AUDIO VALIDATION: reverb-on 8-beat loop") doesn't catch this because it constructs the processor once and runs straight through; the bug needs a steady stream of processBlock calls that each rebuild ChainParams from a fresh stack frame.
  • UI — Eliminated the thin diagonal AA seam at the upper-left/right corners of the orange nose region. The chassis is now filled in a single fillPath with a sharp body→nose gradient stop at redRegionTopY, so there is no horizontal cut to misalign with the silhouette diagonal. Visible in every theme prior to the fix.
  • Nose macros — The 7 macro knobs in the bomb's nose (OUT hero + PITCH/DECAY/PUNCH/WEIGHT/MOOD/SPACE satellites) receive clicks again. NoseComponent's overlay had been intercepting every click in the nose bounds since the 7-tap activation shipped; a new hitTest hook now passes clicks through wherever a macro slider sits beneath the overlay. The 7-tap unlock and BBS re-open still work everywhere else.
  • Scope — Capped WaveBuffer::prevLength_ at 1500 samples (≈750 ms at 48 kHz / kDecim=24). Long reverb tails bleeding above the -54 dBFS silence floor no longer push the next trigger's X-axis to multi-second territory, so a dry kick on the following trigger fills the scope instead of compressing to ~10 % of its width.
  • BBS — ESC now dismisses BBS regardless of where the mouse / focus is. The editor forwards non-modifier keys to BBSComponent::keyPressed whenever BBS is visible, so S / T / N / P / F / R / M / arrows etc. work without re-clicking into the BBS panel first.
  • BBS — T trigger — T fires a one-shot trigger from any BBS screen (Intro / BoomFeed / MyDownloads), matching the main view's T behaviour. Previously the key was swallowed by BBS's catch-all.
  • BBS — preset save — S (save current kick to bank) now works on fresh installs. PresetBank::saveAs creates ~/.config/Bombo/Presets/ (Linux) / Bombo/Presets (macOS/Windows app-data) before writing. The BBS panel also surfaces actual save failures instead of always reporting success.
