Building Groovie, an Advanced Web-Based Drum Machine / Beat SequencerThis is a blog post about a new music app called Groovie that I put together over the last few weeks. It's a fully static website, but it can encode patterns into the hash/fragment part of the URL (a cool, still underrated web trick). Since then, I've created several more advanced web-based music apps, the most advanced one being NoiseCraft. Groovie is a drum/beat sequencer app that uses samples and has a number of advanced features. Groovie uses a few clever tricks to try to encode this information using far fewer bits than a raw bitmap.
