About
EP-PatchStudio is a desktop app that streamlines multisample creation for Teenage Engineering's EP-series samplers, turning a 25–30 minute manual workflow into a couple of minutes. Alongside multisampling it offers device backup and restore, audio editing, and an auto-sampler that can capture hardware synths and VSTs. Multisample creation with looped samples is currently EP-40 only; backup, restore, and file management work across the EP line.
