MIDI CONTROLLER

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

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.

Who Its For

Create a MIDI controller that:
– Encourages play without digital barriers
– Feels emotionally engaging
– Avoids feature bloat in favor of workflow clarity
– Provides tactile feedback through physical components

Design Challenge

01 Research Insights

Key user insights emerged through contextual research, interviews, and observation of studio workflows:

Setup kills momentum

→ Users need plug-and-play simplicity—no menus, no lag

Tactility boosts creativity

→ Knobs and sliders let users “think with their hands”

Generic interfaces fail to connect

→ Materials and form must feel personal, not sterile

Clear layout over complexity

→ Focused design builds confidence and trust

02 Enclosure Design

Compact. Protective. Ergonomic.

Stepped surface separating control zones visually and physically.

03 Interface Design

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.

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.

04 Hardware Design

Four Components. Eight Knobs.

ALL COMPONENTS WERE MANUFACTURED BY MYSELF ON THE METAL LATHE. EACH COMPONENT WAS TURNED AND PRESS FITTED. MEASUREMENTS WERE CRUCIAL IN ORDER TO HAVE THE PRESS FIT WORK (0.001" DIFFERENCE)

05 Electronics Design

POWERED BY ARDUINO LEONARDO, ROTARY POTENTIOMETERS ARE WIRED THROUGH A SOLDERABLE BREADBOARD TO PREVENT FROM COLD CONNECTIONS, ENHANCING THE MIDI’S PERFORMANCE

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.
