About

EP-PatchStudio builds sample kits and multisamples for Teenage Engineering's EP-series hardware, then sends them to your device over USB. Now on iPhone and iPad. If you own an EP-133 K.O. II, EP-1320 or EP-40 Riddim, you know the squeeze: great sounds, a tiny screen and a slow road from a sample on your computer to a pad on your sampler. This app is the shortcut. Import audio, trim it, build a kit and load it onto the hardware. WHAT YOU CAN DO - Import WAV and AIFF from Files, iCloud Drive or straight from another app via the share sheet - Trim, fade and set the start and end of every sample by touch - Build full kits, lay out pads and tune each one (max 8 samples - EP device limitation) - Create multisamples for the EP-40 Riddim, mapped across the keyboard - Send finished kits to your device over USB MIDI - Export kits and backups to Files, AirDrop or your DAW WORKS WITH - EP-133 K.O. II - EP-1320 Medieval - EP-40 Riddim Multisamples are EP-40 Riddim only. No hardware to hand? You can still build and edit everything, then export it for later. Plug in over USB when you are ready to send. FREE AND PRO The Sample Editor is free. Building kits, trimming samples and exporting all work without paying anything. Pro unlocks sending kits straight to your device, as a one-off in-app purchase. Buy once, no subscription. Already bought EP-PatchStudio on Mac or Windows? Enter your licence key to unlock the same here. A NOTE FROM ME I am a solo developer and a sampler nerd. I built EP-PatchStudio because I wanted grown-up software for these little machines, and I keep improving it based on what the community asks for. If something is missing or broken, tell me.

What's New in EP

1.6.0

September 28, 2026

The Stem Splitter now works on iPhone and iPad. On devices with enough memory you can split a song into drums, bass, vocals and everything else, privately and on the device. Keep the app open while it works; the screen stays on, and if a split gets cut off it tells you next time. Also in this update: - Sending files to and from your EP no longer breaks when the device is sending MIDI clock. - Anonymous usage analytics and crash reports stay off until you choose to share them. - When your Pro trial ends, the app offers once to email you a code for more time. - The Stem Splitter's downloads are now called splitter packs, with clearer names. - iOS 15.1 or later is now required. - Smaller fixes and clearer wording throughout.
