I had one of these trivial problems. Yesterday I wanted to create a new stroboscope disc for my Metzner rebuild (now with 50HZ 🙂 … After fiddling around with some graphic tools I decided to build a small Web-App (quick and dirty) to support me on this task. It might be of interest? You can use it offline or via the web site…
Main Features:
– Supports 33⅓, 45, 78 RPM + custom speeds – 50Hz, 60Hz, 300Hz lamp frequencies + custom frequency – Adjustable disk size, bar length, smoothing – Custom colors and logo upload – Drag/rotate/resize logo interactively – Export: SVG (print), STL/3MF (3D print), FreeCAD macro – Light/dark theme, EN/DE bilingual – Offline-capable (standalone download)
This is a web version of the Roland TR-909 drum-machine with painfully hand-made generated html, svg & css and a proper web-audio-api sound engine. It emulates the exact same cumbersome user experience of the original machine.
openDAW is a next-generation web-based Digital Audio Workstation designed to democratize music production by making professional creation tools accessible to everyone.

cplayer is a small, statically served, client-side album-based audio player for modern web browsers. You simply drop a build into a directory on your web server, create a manifest.json file that describes the album metadata and track URIs and you’re done.
A web-synthesizer that generates sound from the binary code of any files. It can synthesize sound directly in the browser, or be a generator of MIDI messages to external devices or DAWs, turning any file into a score. All the application code is written in Javascript and along with everything you need is packed into a single .html file of about 750kb. The synthesizer doesn’t need internet, it can be downloaded and run locally on any device with a browser.
The application reads the file sequentially, and due to the high speed of reading and random deviation of reading duration, we can get quite unpredictable generation of timbre nuances, and at certain settings we can switch to granular synthesis.
