HyperION v1.0.5.0 — Expressive MIDI, Recording Control & Native ARM64

HyperION 1.0.5.0 expands the creative workflow with FL-style note articulations, cleaner recording separation, a substantially upgraded sample editor, stronger plug-in hosting, and native Windows on Arm delivery. This release also closes several stopped-playback audio and plug-in lifecycle issues reported during the 1.0.4 cycle.

Highlights

Added native, FL-style Slide and Legato notes in Piano Roll, independent of MPE mode.
Separated Arrangement, Piano Roll, and Drum Pad recording so each workspace records only when its own REC mode is armed.
Added first-hit recording start for Piano Roll and Drum Pad, persistent project count-in settings, and * / Numpad * transport recording control.
Added editable sample loop points, ping-pong looping, waveform preview, up to +2 dB sample gain, BPM Fit, stretch modes, and Cut Silence at Start.
Improved VST3 and WaveShell discovery, retryable quarantine handling, scan progress, and long cold-start support for Waves catalogues.
Added a professional plug-in wrapper panel with processing, MIDI, GUI, troubleshooting, connection, preset, and automation controls.
Fixed recurring stopped-state Pattern ghost audio, stale C1 step metadata, retained plug-in voices, and pre-stop PDC audio replay.
Hardened plug-in editor close, reopen, and replacement paths to prevent stale editors and asynchronous replacement races.
Added native x64 and ARM64 executables and MSIX packages, plus architecture-aware Setup and Updater delivery.

Piano Roll: Slide, Legato & Note Editing

Slide and Legato are now distinct note articulations rather than MPE aliases.
Slide reuses the preceding voice and glides into the target pitch over the Slide note duration without retriggering the instrument.
Legato overlaps connected notes while preserving a normal target Note-On for mono and legato-capable instruments.
Articulations can be changed from the Piano Roll toolbar, Ctrl + right-click note menu, and Note Properties window.
Plain right-click drag remains the fast erase gesture; Shift + right-click is reserved for MPE editing.
Slide and Legato state is stored with the project and displayed directly on notes.

Recording Workflows

Arrangement recording no longer arms Piano Roll or Drum Pad recording implicitly.
Piano Roll and Drum Pad local REC modes operate independently from the main Arrangement REC control.
When a local REC mode is armed, the first keyboard, MIDI, pad, or mouse input starts playback and is captured instead of being dropped.
Recorded note duration follows the actual press/release interval with a safe minimum length.
Stopping playback finalizes active local notes and Arrangement audio/MIDI clips once, without reopening recording on the next Space press.
* and Numpad * start playback with Arrangement recording; pressing the shortcut again stops recording while transport can continue.
Arrangement and Pattern count-in defaults are off and are saved per project.

Audio Clips & Sample Editor

Added a full waveform view with draggable Start, End, Loop In, and Loop Out points.
Added standard and ping-pong loop playback with loop crossfade support.
Sample gain can now be raised to +2 dB from the editor.
Added BPM Fit / Time Stretch controls with project-tempo follow, pitch preservation, and source/target BPM editing.
Added selectable stretch modes and material-focused algorithms for drums, vocals, speech, textures, low-latency preview, and offline-quality requests.
Improved pitch-preserving playback with allocation-free processing and cubic interpolation in the built-in fallback engine.
Added Cut Silence at Start to the Arrangement clip context menu while preserving the detected transient's timeline position.
Loop, trim, gain, stretch, and tempo settings are persisted with the project.

Plug-in Hosting & Scanning

WaveShell entries from older short-watchdog builds are released from stale quarantine and can be scanned again.
Waves catalogue enumeration now receives a bounded ten-minute cold-start window instead of being treated as a permanent failure.
Timed-out or temporarily unavailable plug-ins remain retryable, while genuine per-binary crashes retain quarantine protection.
Plug-in picker results now exclude invalid/quarantined entries and use stable sorting.
Plug-in editor hosting now adapts to plug-in-driven resizing and display DPI while keeping oversized editors accessible.
Added wrapper controls for processing mode, inactive I/O, MIDI behavior, GUI scaling, parameter notifications, presets, routing, troubleshooting, and All Notes Off.
Added parameter mapping with formula presets, custom formulas, smoothing, conflict handling, and MIDI learn.
Plug-in replacement uses generation checks so an older asynchronous load cannot overwrite a newer request.
Editor teardown is synchronized before instance destruction to reduce close/reopen and replacement crashes.

Playback Stability & Audio Engine

Reset stale Pattern activeVoiceCount state when playback stops so an idle generator graph cannot continue emitting rhythmic ghost audio.
Reset mixer PDC delay history across transport discontinuities so audio buffered before Stop cannot replay afterward.
Repaired stale C1 step/root-note metadata that could pitch a selected sample down unexpectedly.
Added bounded, non-blocking All Notes Off cleanup across MIDI channels and stopped plug-in processing tails.
Prevented VST step/audition playback from creating a parallel synthesized fallback voice.
Improved selected-slot preview isolation and cleanup when changing Pattern lanes.

Licensing & Microsoft Store

Local license material is now protected with Windows DPAPI instead of storing the recoverable key as plain text.
Local activations synchronize with the server /check endpoint and clear invalid or revoked activation state.
Microsoft Store license validation runs only for the real KOSMUSIC.HyperionDAW package identity, so normal EXE and test builds are not incorrectly locked.

Windows x64, ARM64, Setup & Updater

Added true PE x64 and ARM64 builds for HyperION, HyperION AI Setup, and HyperION Plug-in Scanner.
Added architecture-specific x64 and ARM64 MSIX packages for Microsoft Store distribution.
HyperionSetup.exe selects the correct x64 or ARM64 payload for the device.
Added Updater.exe with the same architecture-aware delivery model.
Shared assets remain common to both architectures to avoid duplicate downloads.
