HyperION v1.0.4.0 — Playback Stability, Workflow Fixes & Reliable Plug-in Scanning

HyperION 1.0.4.0 is a maintenance release focused on playback stability, Pattern Mixer reliability, Arrangement editing, VST3 discovery, protected assets, crash diagnostics, and AI safety reporting.

Highlights

Fixed Pattern Mixer channel On/Off, Mute, and Solo behavior.
Improved playback timing and eliminated several stale or repeating Pattern-audio cases.
Reduced clicks and pops during clip playback, seeking, looping, and plug-in changes.
Added the ability to fit analyzed audio to the project key without changing its speed.
Fixed multi-clip duplication placement.
Improved Waves and WaveShell plug-in discovery.
Fixed the plug-in scanner progress bar not reaching completion.
Prevented duplicate Browser entries originating from old build locations.
Added improved Windows crash dumps and diagnostics.
Added functional AI-generated content reporting with offline retry support.

Playback and Audio Engine

Fixed stale Pattern render data continuing to play after Pattern edits.
Fixed old or lower-pitched Pattern notes returning during playback.
Corrected Pattern root-note and per-step pitch handling.
Improved sample-accurate Pattern scheduling across audio blocks.
Improved long Arrangement playback stability and rhythmic timing.
Cleared outdated routing and plug-in delay data after seeks, loops, stops, and other transport discontinuities.
Prevented audio from the previous playhead position leaking into the new position.
Added short safety ramps at clip boundaries to reduce clicks and pops.
Improved clip overlap and crossfade transitions.
Smoothed audio transitions while inserting, removing, bypassing, or reconfiguring plug-ins.
Reduced interface stalls and stale audio while editing Patterns during playback.

Pattern Mixer

Fixed channel On/Off controls so disabled channels no longer process or output audio.
Fixed Solo behavior for Pattern channels and the Pattern master.
Corrected interactions between On/Off, Mute, and Solo states.
Disabled Pattern master channels now clear their output correctly.
Pattern channel enabled states are saved and restored with projects.
Pattern audio is refreshed correctly after changing pitch, velocity, pan, sample, Mute, Solo, or power state.
Improved Pattern channel power-control hit areas and visual feedback.
Improved Pattern Mixer fader visibility and theme-aware colouring.
Pattern sample previews now respect the configured lane velocity.

Pitch Analysis

Added Fit to Project Key after analyzing an audio clip.
HyperION now compares the detected source key with the current project key.
The nearest musical semitone offset is calculated automatically.
Pitch fitting changes the clip's pitch without changing its duration or playback speed.
Repeating the operation no longer accumulates additional transposition.
The available pitch range is expanded automatically when necessary.

Arrangement and Editing

Fixed multi-clip duplication being positioned after the first selected clip.
Selected clips are now duplicated as one complete group.
The duplicated group is placed after the latest-ending selected clip.
Relative timing and gaps between selected clips are preserved.
Improved audio and MIDI selection handling during duplication.
Improved clip fade validation after editing and trimming.
Improved synchronization of reversed and processed clip states.

VST3 and Waves Plug-ins

Fixed the plug-in scan progress bar remaining below 100% after scanning completed.
Improved WaveShell detection and plug-in enumeration.
Increased the scan timeout for WaveShell because it may expose many individual Waves plug-ins.
Previous WaveShell entries incorrectly placed on the blacklist are released for scanning again.
Temporary timeouts and missing dependencies are now treated as retryable conditions.
Slow or temporarily busy plug-ins are no longer permanently blacklisted automatically.
Improved plug-in scanner result and error descriptions.
Improved scanner isolation when a third-party plug-in fails.
Strengthened the Windows crash barrier used when opening native plug-in editors.
Improved fallback to HyperION's generic editor when a native editor cannot open safely.
Improved hosted plug-in editor sizing, preset access, footer information, and theme integration.

Browser and Protected Assets

Fixed sounds appearing multiple times because assets from old build directories were also scanned.
Browser scanning now uses one canonical protected asset location.
Improved Browser cache migration and duplicate cleanup.
Preserved sample author suffixes so legitimately different samples are not merged incorrectly.
Fixed protected assets occasionally being reported as damaged during verification.
Improved recovery when asset mounting is interrupted by an application or system shutdown.
Fixed simultaneous asset-mount workers conflicting while creating directories.
Existing valid mounted assets are reused instead of being rebuilt.
Unchanged protected assets retain their hashes and do not require unnecessary updater downloads.

Crash Diagnostics

Added Windows minidump generation for unhandled HyperION crashes.
Crash reports now include the exception, faulting module, process, thread, application version, and build information.
Crash logs include the path of the matching dump file.
Improved handling of both unhandled and vectored Windows exceptions.
Improved diagnostics for HyperION, HyperION Plugin Scanner, and HyperION AI Setup crashes.

AI Content Reporting

Added Report Issue to the AI Music Generator and Prompt Audio Studio.
Users can report inappropriate or problematic AI-generated results for review.
Reports are stored locally before delivery is attempted.
Reports are queued automatically when the review service is unavailable.
Queued reports are retried after a later application launch.
Successful reports receive a reference ID.
Repeated delivery attempts do not create duplicate reports.
Generated audio, license keys, device names, and machine fingerprints are not uploaded.

Distribution and Updating

Updated HyperION, HyperION Plugin Scanner, and HyperION AI Setup to version 1.0.4.0.
Corrected Microsoft Store package identity and publisher presentation.
Improved Demo, Standard, and Ultimate edition packaging.
Preserved Microsoft Store entitlement verification for production builds.
Updated application and utility icons.
Regenerated the differential update manifest without modifying unchanged protected assets.
Existing projects, presets, settings, licenses, AI credentials, and project media remain compatible.
