Hear the engine.

This is SynthMaker's own audio engine, the same C++ code that plays inside the app, running in your browser. Press play, then turn the knobs.

Play the keys too, or use your computer keyboard: A W S E D F T G Y H U J K.

In the app you build sounds like this one by wiring modules on a patch canvas: a voice, an oscillator, a filter, an envelope, a delay. This page loads that same patch into the same engine. More sounds, and more of SynthMaker, are coming to the web. Meanwhile, join the free beta for iPhone, iPad and Mac, or watch the tutorials.
