“The idea behind the Elk Audio OS is to make a whole new generation of connected musical instruments possible. Instruments that can connect people around the world and spur new kinds of musical creativity. We believe there are so many potential instrument makers out there who could create fantastic things if they just had the right tools, and it is for them we have created Elk. So today I’m very happy to announce that we have reached a major milestone in our company, when we can make Elk available to everyone through the open source release.”
