Sample & Kit Tools
These tools cover the unglamorous-but-essential half of sampling on TE gear: getting audio ready and onto the device. In practice you'll reach for three kinds — sample prep (re-pitch, bit-crush, trim and batch-convert so files fit the hardware's limits), kit and multisample builders (turn a folder of sounds into a ready-to-play instrument), and device managers (import samples, name and colour pads, and back up your work). Pick by what's slowing you down: file size and prep, building an instrument, or moving things on and off the unit.
Top picks
Build a multisample instrument for your EP sampler in a couple of minutes, and back up or restore the whole device.
Shrink and batch-process a folder of samples to fit the EP-133's size limits, or design single-cycle waveforms.
Prep and re-pitch a sample, then bake EP-133 playback settings into the file so it loads ready to play.
Good to know
- •Most browser tools that write to the device need a desktop Chromium browser (Chrome or Edge) and a USB connection.
- •EP samplers cap onboard sample memory, so prep tools that shrink or down-sample files are often the difference between a kit fitting or not.
