How it works

1

Drop in any song

AI splits it into stems: drums, bass, guitar, vocals. Each instrument isolated, ready to play with.

2

Pick your instrument

Mute what you want to play. Guitar? Bass? Drums? The rest of the band stays. Your seat opens up.

3

Play along

The band reacts to you in real time. Speed up, slow down, get loud -- they follow. Like musicians who actually listen.

Not a backing track. Not karaoke.
A room where musicians listen to each other.

Built for the musician who practices alone but wants to play with others.

The stack

Android Kotlin Oboe C++ Elixir RunPod GPU

Native audio. Sub-10ms latency. Because music can't wait.
