If you have a PRO membership, you can add music to your mashes.
To do it, follow these quick steps:
Tap the Play/Mash button at the bottom-center of your project's grid view to start creating a mash.
Select "Music" from the mashing options.
To listen to the music, tap on the track's name.
Once you've found the track you want to use, adjust the volume if needed, and then tap "Done".
