Can I Export Beats to MP3 / M4A / AAC?

Exporting beats is not currently possible in Drum Beats+ 4.x, however, we do support Inter-App Audio, Apple’s app-to-app audio streaming framework.

IAA lets you stream Drum Beats+ audio directly into apps like GarageBand to jam and record in real-time. You can add effects from GarageBand and record your song ideas as inspiration hits.

Here is a list of IAA-compatible apps:
