Jam in time wirelessly with your modular gear

Desktop Modular Clock Generator with Ableton Link Integration


The Missing Link was inspired by the many attempts to synchronize friends at synth jams and meet ups. Someone is always too far away to get a patch cable to, or someone gets left out because they don’t have a way to clock, or another person has to compromise their unique setup to accommodate others.

The Missing Link makes it easy for Modular, iOS, and Desktop musicians, DJs, and noise-makers to synchronize their unique setups to jam in time using any available WiFi network.

Built upon the rock solid Raspberry Pi Zero W platform and Ableton’s Link API, Circuit Happy hand-crafted a small hardware box that is both functional and fun to use.

The Missing Link runs open source software built around Ableton’s Link technology. This means you share tempo and loop information amongst all the Link-enabled devices. So when you hit play, it waits to start the clock on the downbeat, in time and on time.

Easy WiFi Setup

When you first boot up The Missing Link it won’t know about your home or studio WiFi network. Once it detects that there is no netork connection The Missing Link will go in to “Access Point Mode” where it will become its own WiFi router. You then connect your mobile or desktop computer to The Missing Link’s WiFi access point, open a browser to a web page hosted on The Missing Link, and configure it to connect to your home or studio WiFi netork. The Missing Link reboots and it will now know how to get on to your network.

Just power it up, connect to the WiFi, and start jamming!
