VybeCode DSP has announced an update to its free, open-source desktop tool for audio plugin GUI developers. Available for Windows 10/11, StripKit takes a single transparent PNG of a control — a knob, fader, slider, or meter — and renders the entire filmstrip (sprite sheet) that plugin interfaces use to animate it: every frame, frame-perfect, correctly rotated, supersampled, and crisp at any resolution.
Audio-plugin interfaces animate their controls with a filmstrip: one tall PNG holding every frame of the control stacked top-to-bottom, where the plugin displays frame N for parameter value N. Hand-authoring those strips — rotating a knob through 64 positions by hand, keeping every frame pixel-aligned, re-exporting at @2x — is tedious, repetitive, and easy to get wrong. StripKit does it automatically in seconds.
“Every plugin developer has spent an evening they’ll never get back nudging a knob around in an image editor, frame by frame. StripKit removes that step entirely — and with the new code export in 0.7.0, it removes the next step too. You go from a single drawing to a fully animated, wired-up control without writing the loader by hand. We made it free and open source because asset tooling like this should be a baseline, not a paywall.”
Changes in StripKit v0.7.0
- Code / component export. Every export can now also emit ready-to-paste loader code for the target framework — no hand-wiring. StripKit ships four targets: JUCE (a LookAndFeel filmstrip slider, or a meter component), CSS/HTML (a self-contained background-position sprite with a 0–1 value setter), iPlug2 ( IBKnobControl / IBSliderControl / IBitmapControl ), and HISE (a ScriptPanel paint routine). Preview the snippet live and copy it to the clipboard, or tick targets to write one file each next to the exported PNG.
- Value arc / fill ring for knobs. An optional Serum/Vital-style fill arc, baked into each knob frame, that tracks the value as the knob turns — with configurable radius, thickness, colour, round or butt end caps, an optional dim track, a two-colour sweep gradient, and a glow.
StripKit is released under the MIT license — free for personal and commercial use, forever. The full source is public on GitHub, and contributions, bug reports, and feature requests are welcome. A public roadmap outlines what’s next, including layer-aware animation, additional code-export targets (React / Web Component, Unity / Godot), and web/animation exports.
