The Radial Key Largo line mixer is the most transparent mixer anywhere near its class that I’ve ever used. That, and it’s compact size, make it an amazing choice for lots of applications, not just for keyboards. I can’t think of a better choice, unless you need a mic pre and/ or eq in your mixer. I love the fact that it only uses digital I/O where it is necessary–in it’s computer audio inferface section (96k/24 bit), and the rest of it is transparent analog. A great choice for using Eventide FX units, Eventide’s compact mic pre, etc.
