Drumbridge

Sample manager for Teenage Engineering EP-133 K.O. II, EP-1320 Medieval, and EP-40 RIDDIM.

A native iOS / iPadOS app that connects to your EP groove box over USB-C and gives you everything the device’s small screen can’t: a full sample browser, project playback, backup & restore, and Ableton / MIDI / stems export — all offline, no account, no cloud.

Drumbridge is an independent project. Not affiliated with, endorsed by, or sponsored by Teenage Engineering AB. All product names are trademarks of their respective owners and are used solely to describe compatibility.
