The Story Behind Tandem

A collaborative MIDI canvas designed for musicians who want powerful control over their performance.

The Tandem Mission
Reimagining MIDI control for modern musicians
Tandem App in Use

Tandem was born from a simple idea: MIDI controllers should be as flexible and creative as the musicians who use them. As a performer and producer, I found myself constantly switching between hardware controllers, never quite finding one that could adapt to my evolving workflow.

I envisioned a controller that could transform from a drum pad to a mixing console to a synth controller with just a few taps — one that could be designed on the fly to match the needs of any performance or studio session.

But beyond just flexibility, I wanted to create something that fostered collaboration. Music is inherently collaborative, yet most MIDI control solutions are designed for solo use. Tandem changes that by allowing multiple performers to connect and control the same session together over a local network.

Core Principles

Flexibility

Adapt to any workflow with customizable layouts and controls

Collaboration

Connect multiple devices for synchronized creative control

Accessibility

Transform any iOS device into a powerful MIDI controller

From solo bedroom producers to professional stage performers, Tandem is designed to enhance creativity and streamline workflow. As the app continues to evolve, our focus remains on empowering musicians with tools that inspire rather than constrain.

Mitchell Cohen

Hi, I'm Mitchell — a musician, developer, and the creator of Tandem. With a background in both music production and software development, I've always been fascinated by the intersection of technology and creativity.

After years of frustration with rigid MIDI controllers that couldn't adapt to my needs, I set out to create the solution I always wanted. Tandem is the result of countless hours of development, testing, and refinement based on feedback from fellow musicians.
