Tactile Audio Interface for Emerging Creators
Tactile Audio Interface for Emerging Creators
A four week-long individual project at the Rhode Island School of Design (RISD), exploring how physical interaction can empower digital music-making.
The goal: design and fabricate a MIDI controller that minimizes setup friction and enhances creative flow through intuitive, tactile control.

Overview
Overview
Emerging music producers aged 19–30 working in compact home studios, bedrooms, or university labs. These creators often switch between laptops, synths,
and hardware in tight spaces and crave gear that feels immediate, expressive, and personal.

INTERFACE 1
Split zones with knobs and single slider.
Simple but feels disconnected and lacks interaction variety.
Balanced layout with knobs, sliders, and one big dial.
Visually clean but too rigid, less intuitive flow.
High knob density with two sliders on top.
Offers control but overwhelming and lacks hierarchy.
Clear hierarchy: knobs, sliders, and master control.
Balanced, intuitive, and supports creative flow without clutter.
Best fit for portable, ergonomic, and user-friendly control experience.

INTERFACE 4
two sliders
This FINAL Interface combines eight knobs, two sliders, and a master knob in a clear, intuitive layout. It balances detailed and broad control, supporting the purpose of delivering ergonomic, tactile interaction for fluid music-making in any setup.

Full-Scale MIDI Controller Concept — 9 Rotary + 2 Linear Potentiometers (11 Inputs)
This version represents the intended fully-scaled design, expanding the MIDI controller to handle up to 11 independent inputs, limited only by hardware constraints of the Arduino Leonardo.
This version reflects the functional final prototype, utilizing 3 rotary potentiometers to match the actual analog input capacity and wiring limitations of the Leonardo-based build.
