New module!

We're delighted to announce a new Eurorack module, the ES-10.

The ES-10 is an 8-in/8-out ADAT interface, with DC-coupled inputs and outputs that can be used for both audio and CVs.

Each input can be individually selected for modular or line level operation.

The outputs can be expanded via the ES-5 module.

The ES-10 uses AKM 'VELVET SOUND' DACs and ADCs and low noise audio op-amps for the best possible sound quality.

Available immediately, stock permitting - see
Where To Buy.

"Instruments that sound good inspire better music, and it's a struggle to make music with bad-sounding instruments, irrespective of how talented you might be. Software instruments are no different: although they are usually discussed and sold in terms of their 'features'  what really makes you return to an instrument repeatedly is the much more elusive factor of inspirational sound quality.

"I don't know enough about programming to understand why some software tools fascinate you while others make you want to get another job, but I do know that when I use anything by ES I get excited by what I'm hearing. These tools have the sonic richness of great analogue instruments - with the features of innovative digital ones."
