bandmates

Introduction

Tired of the bass player stealing the spotlight? (Or maybe you just want to practice guitar without Dave's questionable timing). This app lets you kick out any instrument from your favorite tracks and play along instead 🎸. I built it because I needed a drama-free way to practice guitar – no band drama required.

Strips out instruments tracks from any song, letting you jam along with the band! 🎸
