Release v0.9.5-alpha · chips047/Cassette

Post - load audio editing is finally here! You can now re - trim your track, tweak fades, or change the BPM anytime after loading it.
Fresh icons in the Project Menu, all hand - drawn by me :)
A new, proper tutorial is now included to help you get started without the guesswork.
Track names always stay on top of glyphs and now dynamically shift their color to match the background so they are always readable.
Keyframe shortcut: When Keyframes mode is active on a glyph, you can now tap the [ and ] keys to quickly raise or lower brightness points.
Animated history: Undoing and redoing glyph movements or length changes is now smoothly animated.
A new setting: Toggleable glyph rounded corners.

Smarter rendering for tiny glyphs:
- Glyphs smaller than 15px now switch to sharp corners. This looks much cleaner at small scales and gives a nice FPS boost.
- Glyph borders dynamically shrink from 2px down to 0px as glyphs get smaller, keeping things clean and readable.
- Selected tiny glyphs keep their default border thickness so you never lose track of what you have selected.
Better Audio Delay Setup animations. Added a textbox so you can set the milliseconds yourself.

Massive rendering overhaul: Thanks to a new occlusion system, hidden glyphs aren't rendered at all anymore. The app easily hits a rock - solid 120 FPS. Because of this:
- Noticeably higher frame rates across the board.
- No more lag spikes when spam - spawning glyphs.
- Silky - smooth zooming, no matter how crowded your canvas is.
- Marquee selection and dragging still work seamlessly on glyphs tucked behind others.
- Bulk - deleting large amounts of glyphs is significantly faster.
Less disk space used: Save files are lighter, and if your audio track does not need trimming, the app will no longer generate a redundant cropped audio file.
Lighter footprint: Completely dropped Mutagen from Cassette dependencies.
Optimized undo / redo actions.
Optimized glyph deletion.
Optimized glyph move and resize.

Fixed weird playhead behavior when it is at the end.
More fixes for Floating Window incorrect sizes.
Fixed an issue where you could paste massive walls of text into textboxes that were never meant to handle them.
Fixed a window bug where short audio files combined with a low default zoom caused compositions to open at a broken scale instead of going fullscreen.
Fixed weird composer window scaling when resizing mid - opening animation.
Fixed a glitch where spawning a glyph right as playback began would launch it completely outside the composer bounds.
Spawning glyphs during playback now respects your audio latency settings (positive delay advances the playhead, negative delay pulls it back).
Fixed multiple stability issues when GPU rendering is turned off.
Fixed glyphs loading into incorrect positions when opening saved compositions.
Squashed several errors that happened while loading audio files.
Fixed broken Undo / Redo (Ctrl + Z / Ctrl + Y) behavior when editing Keyframes.
Fixed odd slider behavior in context menus: previously, moving the Gap slider in the Chase effect from 0 to 1 did nothing until you moved it to 2, after which 1 would suddenly work. It now updates properly on every step.

Extracted most hardcoded values into a clean, dedicated Constants.py file.
Split oversized, monolithic files into smaller, modular components for cleaner and more maintainable code.
Applied general performance and memory optimizations across all core systems.
