One Platform. Every Instrument.
Fee[dB]ack is designed around the idea that every musician should be able to participate.
Play guitar, bass, drums, vocals, or keys using dedicated gameplay experiences tailored to each instrument. Jump into split-screen sessions with friends, practice your own parts, or perform together as a complete band.
No matter how you choose to play, Fee[dB]ack gives you the tools to learn, improve, and make music together.
Instruments
Guitar
Plug in your electric or mic up an acoustic — real-time note detection follows every note, bend, and chord as you play the highway.
- 3D note highway built around strings and frets
- Alternate tunings, capo support, and a built-in tuner
- Slow down, loop, and drill the hard riffs until they land
Instruments
Bass
Dedicated bass arrangements put you in the pocket — lock in with the drums and carry the song, with detection tuned for the low end.
- Bass-specific charts, not guitar hand-me-downs
- Groove and timing feedback as you play
- Works with any audio interface, 4 strings or 5

Drums
Hook up an e-kit over MIDI or mic your acoustic kit — the drum highway shows every hit across the full kit, from hi-hat to kick.

- E-drums over MIDI, acoustic kits over mics
- Build limb independence one pattern at a time
Instruments
Keys
Connect any MIDI keyboard and play piano and keys parts on a highway that mirrors the keybed — every octave, both hands.

- Full MIDI support — velocity, sustain, and all
- Theory training that connects to what you play
Everything you need to play — and keep getting better.
Per-instrument highways
3D note highways tuned to how each instrument is actually played — guitar, bass, drums, keys, and vocals.

Isolate parts, slow down without changing pitch, and loop the hard bars until they're easy.
Theory & lessons
Music theory training and guided lessons that connect what you play to why it works.
Minigames
Arcade-style drills that sharpen technique while you're having fun.
Plugin ecosystem
Every feature is a plugin — swap them, configure them, or build your own.

Every name up here earned its place. No scores, no rankings — just deeds.

Author it. Audition it. Repeat.
That's why Fee[dB]ack was designed with extensibility at its core. Through a powerful plugin environment, developers can create new gameplay systems, tools, interfaces, training experiences, and entirely new ways to interact with the platform.
Whether you're customizing your own experience or building something for everyone, the possibilities are limited only by your imagination.
Open Source
Free to play, free to read, free to build on.
GitHub
The got-feedback organization — core app, desktop builds, and the whole plugin family.
feedpak spec
The open file format for interactive charts. Fully documented, no lock-in.
Build a plugin
Nav links, screens, settings panels, gameplay — plugins can add all of it. If you can write a little JavaScript and Python, you can extend fee[dB]ack.
