This page is for musicians who just need to take a normal song (MP3/WAV) and get drums-only from it — for practice, covers or transcription. Beatisolate runs in the browser, so you don’t have to install anything.
Does it work with MP3? Yes. 1 upload = 1 task.
Do I need to install anything? No, runs in browser.
Can I do just MIDI/GP? Yes, that’s the second workflow, and it is processed as a separate task.
