What the developers have to say:

Why Early Access?

“Tomo Jam already delivers a complete local co-op and single-player sandbox, but there’s more music to make. Early Access lets players jump in early, share feedback, and help shape the future of the game. We plan to develop new single-player and multiplayer modes (including a campaign) and full online multiplayer.”

Approximately how long will this game be in Early Access?

“About one year. We want enough time to build and refine the new features, especially online multiplayer and the campaign mode, while incorporating community feedback. The goal is to make sure everything feels smooth, fun, and musically rewarding before the full release.”

How is the full version planned to differ from the Early Access version?

“Our plan for the full version of Tomo Jam is to expand on what’s already there with additional single-player modes, a full campaign, and full-featured online multiplayer. We’re also planning to improve the song tools, add more customization options, and polish the overall experience based on what players share during Early Access.”

What is the current state of the Early Access version?

“The Early Access version of Tomo Jam includes full single-player and local multiplayer support for up to four players. Players can perform any of the included and original MIDI songs, or add their own custom MIDI files to play instantly. All core gameplay features are complete — including multiple difficulty modes, tempo control, and adaptive note ranges that make every song playable on a controller.

The game is fully stable and feature-rich enough for endless jam sessions, but there’s still plenty of room to grow. During Early Access, we’ll be focusing on online multiplayer, expanded single-player modes (including a campaign), and general polish based on community feedback.”

Will the game be priced differently during and after Early Access?

“Yes. During Early Access, Tomo Jam will be available at 50% off its planned full release price. As planned features like online multiplayer, campaign mode, and expanded tools are added, the price will gradually increase toward the full release value. Early players get the best deal and a front-row seat to the game as it grows.”

How are you planning on involving the Community in your development process?

“Community feedback will be a big part of Tomo Jam’s development. Players will be able to share ideas, report bugs, and suggest new features through Steam discussions and our Discord server.

We’ll be listening closely to what players enjoy most, from favorite difficulty settings to how they use custom MIDI files, and using that input to guide updates, polish gameplay, and shape new content like the campaign and online multiplayer. Early Access is our chance to jam together, experiment, and build the best version of Tomo Jam as a community.”

About This Game

Tomo Jam

Play music your way with nothing but a controller.

Tomo Jam turns your game controller into a playable musical instrument.
Press buttons to play real notes, shape phrases in real time, and perform full songs with surprising musical depth. Jam solo or form a chaotic four-player band on the couch as every hit (and miss) becomes part of the music.

A Rhythm Game That Lets You Play Music

Every button press produces real sound. Notes respond instantly to your timing and input, making each performance feel expressive and alive. Whether you’re following the chart, improvising freely, or accidentally hitting the wrong note, the music never stops.

It’s intuitive to pick up, expressive to master, and often hilarious when things go off the rails.

Grow From Beginner to Full-On Master

Tomo Jam adapts to how you want to play.

  • Novice lets you jump in with a single button and no pressure

  • Amateur introduces more notes while staying approachable

  • Pro and Master unlock deeper layouts where precision and expression matter

As the difficulty increases, the music opens up. Dense passages stay playable, fast runs feel musical, and higher levels reward confident, expressive play.

Improv, Ornamentation, and Musical Freedom

Some sections invite you to break away from the chart and improvise freely.
Fast musical flourishes are transformed into playable phrases so even complex music can be performed by human hands.

The result is a rhythm game that feels less like memorization and more like playing an instrument.

Your Music, Instantly Playable

Tomo Jam includes a growing selection of built-in tracks, but the real magic begins when you add your own.

Drag and drop any MIDI file and start playing immediately. Songs are mapped automatically, letting you explore everything from classical pieces to jazz, or your own compositions.

No setup. No editing. Just play.

Jam Solo or Together

Play alone or with up to four players locally, each with their own instrument and lane. Perform together, improvise over one another, or descend into joyful musical chaos.

Online multiplayer is in development and will be added during Early Access.

Early Access and Beyond

Tomo Jam is launching in Early Access and will continue to grow with new features, modes, and improvements driven by player feedback.

Whether you want to learn, experiment, or just make a joyful mess of music, Tomo Jam is a rhythm game built to let you play.
