The Touellskouarn Eread Jedonian is a quad splitter from TRS to 2x mono mini jack combined with a bidirectional Hz/V converter. Additionally it offers V-Trig to S-Trig conversion.

The Hz/V standard works with Korg MS and old Yamaha CS among others. 

They are jumpers on the back of the module, so you can choose to also use it like the other splitters. It was designed to be used with the New Akai© MPCs. The MPCs have 4 Strereo jacks cv output, with this module you can patch the 4 stereo cables in the stereo inputs, and the module will split the mono outputs.

You can also use it as a Stereo maker, if you input 2 mono signals, they will be availlable in a stereo form at the stereo jack.
