  1. Are you referring to Firewire versions? Because the USB ones are same price as this. Less I/o for sure. The ES3 is around 300.

  2. I’d just love to see a Windows solution so I can start playing between Reaktor and my modular gear. Please Expert Sleepers release a Windows version of the ES-8

      1. Yes, MOTU have DC coupled outputs. I said DC coupled inputs. No audio interface that I know of has DC coupled inputs, other than the ES-8.

  3. Looks tempting to me, pretty comprehensive way to control and record a eurorack system without a stack of adapters and extra input/output modules.

    Once windows deivers show up ill give it another look.

  4. Been piping my modular’s output through one or two lines, simply due to lack of inputs on my audio Interface. Makes it a pain to try to edit out mistakes after the fact, but it also prevents me from becoming a control freak and endlessly tweaking the mix.

    Honestly, I’m not sure if a product like this would be a good thing or a bad thing for my workflow, but I’m glad to have the option. Of course, for that price, I could buy a Focusrite 18i20, which would perhaps be a more versatile option for my studio as a whole.
