A web app for building sample libraries for Teenage Engineering devices. It started with the OP-1, OP-1 field and OP-Z and was extended to the EP-133 K.O. II. Upload a batch of audio files, cut them up, reverse them, make sub-selections for quick sample chains, and rename them. On the EP-133 you can send them straight to the device and assign samples or slices to pads, adjusting the slices live. It works like the official sample tool, with an extra personal library you build up over time. A short tutorial is built in.
