Free Stem Splitter for Instrument Practice
Split songs and practice for free, with no daily or monthly upload quota. What is included, how downloads work, and the dedicated Stem Splitter app for iOS and Android.
The Free Stem Splitter turns a song into separate parts you can listen to, mute and play along with. Standard splitting and instrument practice in the Studio are completely free. Upload as many songs as you want: there is no daily or monthly upload quota, no pack of practice credits to use up, and no subscription needed for the core practice tools.

#Start a practice session

- Set up your instrumentOpen Chords and switch to Practice Mode for guitar, ukulele or piano diagrams. Singers can follow Lyrics and shift the pitch to match their range; bassists and drummers can solo their stem to study the groove.
- Loop, slow down and play alongSelect a difficult section and turn on looping. Lower the tempo while you learn it, then work back toward the original speed. Adjust the other stems and metronome to build the practice mix you need.
#Unlimited uploads, with a limit per file
There is no upload-count limit for free practice. Each stem-split upload can be up to 1.5 GB and 22 minutes 30 seconds long. Split one song at a time; cut longer recordings into shorter tracks. These are limits on an individual file, not a daily or monthly allowance of songs.
