What's new since 1.6.0

A behind-the-scenes real-time-safety and performance pass — no new UI, no new engines. Everything below was verified end-to-end (real before/after audio diffs, not just "tests pass").

• Live parameter updates are now genuinely event-driven. Previously, every audio block rebuilt every operator/LFO/envelope/filter's live parameters regardless of whether anything actually changed — a real (if usually inaudible) CPU cost, worse the more voices are sounding. Automation and knob changes now only trigger work for the parameter groups that actually changed.
• Lower average CPU load, most noticeable on patches using master-bus effects, active modulation, or granular textures — internal benchmarks measured a real ~17% reduction on the core per-voice render path and ~2-5% on full-patch rendering.
• Fixed a real pitch-independent tuning inconsistency: the Classic engine's Triangle waveform and the Phase/Shape engine's Wavefold amount both had a subtle character that shifted slightly with project sample rate (44.1kHz vs. 48kHz vs. 96kHz) — the same patch could sound very slightly different depending on your session's sample rate. Both now render consistently across sample rates.
• Granular engine's grain envelope now uses a precomputed lookup table instead of a live trig calculation per grain per sample — measurably cheaper with no audible difference (verified to a fraction of a millionth of full scale).

Troubleshooting

Problem	Fix
Logic says "incompatible"	Delete old MURMUR.component, reinstall 1.6.1 pkg, rescan
Blank plugin window	Reinstall pkg (content missing); try Standalone app first
A saved project sounds slightly different after updating	Only affects Triangle/Wavefold-heavy patches rendered at a non-48kHz sample rate — the new render is the more correct one; if you need the exact previous character, contact support and mention this release note.

What's new since 1.5.0

• Branded splash screen — real kelp-forest + whale artwork on launch, fixed-duration progress bar with honest phase labels (not a fabricated loading percentage).
• License activation — a new ACTIVATE YOUR ENGINE screen accepts a license key (generated at murmur-web's /keys page) and syncs a starter patch library from murmur-web's live backend into your local preset folder. Optional — SKIP FOR NOW dismisses it with no consequence; nothing is paywalled yet.
• Installer polish — the DMG now opens to a real branded Finder window (same kelp/whale artwork) instead of a plain file list, with one clear action (Install MURMUR.pkg) plus a Documentation/ folder instead of six loose text files.
• .pw8 → .murmur packaging fix — the release script's factory-preset bundling logic was still matching only the pre-rebrand .pw8 extension; fixed to match both, so this and all future releases bundle the real 1,129-preset factory library (including the full 175-file Interstellar bank) rather than a smaller placeholder set.

Troubleshooting

Problem	Fix
Logic says "incompatible"	Delete old MURMUR.component, reinstall 1.6.0 pkg, rescan
Blank plugin window	Reinstall pkg (content missing); try Standalone app first
Gatekeeper blocks pkg	Right-click → Open
No presets in explorer	Confirm ~/Library/Application Support/MURMUR/Presets/factory/ has .murmur (or legacy .pw8) files
