Video Import

• Fixed the app becoming unresponsive when a video was opened without FFmpeg installed
• Video imports now remain pending while the FFmpeg download prompt is open and continue automatically after FFmpeg is installed

Modulation

osci-render (both versions)

MIDI Program Change

• MIDI Program Change messages can now select visuals in the current project
• Program Change 0 selects the first visual, Program Change 1 selects the second, continuing through the first 100 visuals
• Program Change input can be disabled, received on all MIDI channels (omni), or limited to a specific channel from 1 to 16
• MIDI Program Change settings are available by clicking on the current file name
• The standalone app remembers the selected MIDI channel globally, while plugin instances save it with the host project

File Controls

• The current file name is now interactive, with a context menu when clicked
  • New file actions: Edit file for text and Lua files, Rename file, Duplicate file, Export file, and Remove file
• File Select automation and out-of-range Program Change selections resolve to the nearest available visual instead of leaving an invalid selection
• Existing projects retain their saved file order, embedded content, and current selection

MIDI and Output Routing

• New MIDI input channel selection, Panic, and Kill Voices Immediately controls
• New Swap X/Y, Invert X, and Invert Y output controls

Animation

• Supported animated files now play at their embedded frame rate, including GIF and GPLA in both versions, plus video and Lottie in premium
• Animation Rate has been replaced by a modulatable Animation Speed multiplier
• Existing projects using Animation Rate are converted to an equivalent Animation Speed value without changing their playback speed
• Negative Animation Speed values play animations in reverse
• GPLA files now use their stored frame rate

Fixes

• Fixed the Lua editor briefly stalling when reporting the first syntax error
• Fixed slowdowns when moving between effect previews
• Fixed animated drawings stuttering or becoming desynchronised when consecutive frames have different path lengths

sosci + osci-render (premium only)

Transparent Visualiser

• New Transparent Background option which works with all screen overlays
• Transparent visualiser windows on macOS, Windows, and supported Linux desktops
• New window controls for showing or hiding the frame, always on top, click-through, full screen, and closing the window
• Pausing restores the popout controls, and the popout can also be closed from the main visualiser
• Both applications now remember whether the visualiser popout was open between launches

Transparent Video Recording

• New ProRes 4444 recording option with transparency support
• Enabling Transparent Background automatically selects ProRes 4444 and saves the recording as a .mov file
• ProRes 422 HQ remains available for recordings without transparency

Texture Sharing

• Texture inputs can now be selected directly from the Video menu, with source application names and dimensions shown when available
• Texture output now follows the current visualiser frame and uses the selected rectangular or custom canvas size
• Clearer status and error overlays are shown when a texture source disappears or texture input or output cannot start
• Closing an editor, disconnecting a texture source, or switching back to project files now clears texture input cleanly and restores the selected visual

Offline Audio-to-Video Rendering

• Improved cancellation and missing-frame handling

Visualiser and Recording

• New rectangular visualiser canvas support for preview, recording, offline rendering, and texture output
