The core idea was to create a controller that could instantly link to any software instrument and offer rich, tactile control over its parameters. The initial concept featured a modular system, where users could insert different physical modules into a base to represent various digital instruments and effects. However, user testing revealed that the modularity added complexity without delivering meaningful value. What resonated more with users was the ability to instantly map physical controls to software parameters. This insight led to a significant design shift: a fixed-layout controller with knobs and buttons, each accompanied by a small screen showing its current software mapping and parameter state. This approach generated more user interest. We further refined the prototype and began testing it in real-world settings with musicians. Traveling around the Netherlands to test with variety of artists ranging from audio designers, such as Joep Wiertz in Enschede, to professional musicians as Polynation in Amsterdam. These insights informed the development of the final design, ultimately renamed the Logue CL-1, a controller that we believed best addressed the core user need for expressive & enjoyable software control. In this process, we partook in the START program from NovelT at the University of Twente and thereafter entered the ADVANCED program, which included direct coaching from two business coaches.
