Groovesizer is a DIY granular synth originally running on Atmel chips. It features two voices, a step sequencer, patch saving, and a simple but elegant interface designed for live performance.</p> <p>The goal of this project is to modernize the hardware and extend it with AT Protocol integration, turning it into a networked, interoperable instrument.</p> <h2 id="at-protocol-integration">AT Protocol Integration</h2> <p>Adding ATProto connectivity to the Groovesizer hardware opens up several possibilities:</p> <ol> <li><strong>Live state sync</strong> — Share knob and switch state between devices in real time during a live setup.</li> <li><strong>Preset sharing</strong> — Publish saved presets on a button press; load them on another device instantly.</li> <li><strong>PDS persistence</strong> — Store live and preset state on a Personal Data Server (PDS), making patches available across the ATProto network and interoperable with other apps. Includes backup via PDSMover and event triggers via If-This-Then-AT.</li> <li><strong>Universal controller via panproto</strong> — Share live and patch state across hardware devices and software synths, making the Groovesizer a universal controller for AT-enabled music instruments.</li> </ol> <h2 id="groovesizer-blue--workshop-edition">Groovesizer Blue — Workshop Edition</h2> <p>A workshop-ready kit designed to be accessible for beginners:</p> <ul> <li>PCB arrives pre-soldered, with only a few through-hole parts (e.g. jumper connectors) left for manual assembly.</li> <li>Switches and potentiometers are connected via jumper cables that can be hand-soldered before the session.</li> <li>Optimized for build workshops where participants complete a working instrument in a single session.</li> </ul>
