PRAXXIS

PRAXXIS is the music practice app that does something no other app can do. Drop in any song - any MP3, WAV, AIFF, or M4A from your library. PRAXXIS instantly detects the chords, key, tempo, and time signature. Then its on-device AI separates the song into individual instruments: drums, bass, guitar, piano, and vocals. Solo the bass line. Mute the vocals. Slow it down to 50%. Read the auto-generated notation. Practice your part with the rest of the band playing in your headphones. Everything runs on your device. No internet required. No uploads. No cloud processing. Your music never leaves your phone.
