In ancient Greek thought, « Logos » originally designates spoken or written discourse.
By extension, it comes to signify reason itself, considered as stemming from the capacity to use language.
From this notion derives the idea of logic, which corresponds in the Latin world to the art of correct and rational thought.
To compose is to articulate discourse

“You have a good time when you work with the Logos”My 2 cents
« This MIDI controller is really a success, designed for composers and creators. Honestly, you get used to its comfort and flexibility very quickly. Navigation is super intuitive, with buttons and keyswitches that perfectly replace those on a keyboard, which is very practical. I love being able to change presets or CC ranges in the blink of an eye—it’s very smooth, and the screen is very readable, with values and names clearly displayed. It has a very organic approach that saves time. In short, this controller is ideal for film music or production. And now that I’ve tried the Logos, I’m honestly wondering, « How could I live without it? »! »
