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.

IspΓ­n adds weight, warmth and grit to thin-sounding tracks. Push it gently for compression and glue, or drive it hard for full distortion. Four controls, no menus, nothing to set up. RICHNESS: Density and drive. Goes from subtle thickening to heavy saturation. COLOUR: Tilts the harmonics dark to bright, so the dirt sits where you want it. ROUGHNESS: Drives the waveform off-centre for buzz, grind and edge. OUTPUT: -18 to +6 dB of trim, for a level-matched A/B against your dry track. At zero, IspΓ­n passes audio at unity gain β€” so bypass tells you what you added, not just what got louder. Six presets included: Grand So, A Bit of Dinner, The Crispy End, Hot Tea, Full Breakfast Consequences, and I Left the Immersion On. Save your own alongside them. The interface resizes to fit the space your host gives it, in portrait or landscape. Note: This is an Audio Unit Effect Plugin (AUv3), which requires a host such as AUM or Loopy Pro – or a DAW such as GarageBand, Logic Pro or Cubasis.
