How to Manage Samples on Your EP-133 K.O. II from Your Computer
Browse, upload, download and tidy the samples on your EP-133 K.O. II from your desktop with EP-PatchStudio's File Manager, with a Recycle Bin so a mistaken delete can be undone.
Managing samples on the EP-133 K.O. II from the front panel works, but it gets fiddly once you've got a lot of sounds. From your computer it's a clearer picture: you can see everything at once, add new samples, pull sounds off to back them up, and clear out the slots you don't need.
Here's how to do it with EP-PatchStudio's File Manager.
What you'll need
- An EP-133 K.O. II and a USB-C data cable (some cables only carry power, and those won't work)
- EP-PatchStudio installed (download it free)
- The device powered on and connected before you open the File Manager
Connect and browse
Open EP-PatchStudio with the EP-133 connected. The File Manager loads every sample from the device and lays them out so you can see how your samples are arranged. The category view adapts to your device, so you're looking at the EP-133's own layout rather than a generic list.
A couple of things worth knowing. Samples are read live from the connected device, so what you see is what's actually on the EP-133. If you disconnect mid-session, reconnect before making changes. And if the File Manager shows empty slots when you know the device has samples, check the cable is a data cable (not charge-only) and that the device is on.
Upload samples to the EP-133
To get new sounds onto the device, add your WAV files in the File Manager. For reliable imports, a sample rate of 44.1 kHz is a safe default, trim the silence off the front of each file so pads trigger tightly, and name your files sensibly before importing.
If you want to prepare a whole folder first, normalising, trimming or converting it, run it through the Batch Processor before you upload.
Download samples to your computer
Pulling samples off the device is just as straightforward: select what you want and download it. It's the way to back up a sound you might want again later, or pull a one-off recording into your DAW. One good habit: download anything important before you delete it. Once a sound's gone from the device and you've no copy, it can't be recovered.
Tidy up: delete and the Recycle Bin
Clearing out unused slots keeps the device manageable. When you delete a sample in EP-PatchStudio it goes to the Recycle Bin rather than disappearing on the spot, so a mistaken delete can be undone. Treat the Bin as a short-term safety net rather than a backup, though, and keep real copies of anything you care about.
File Manager or Backup & Restore?
These do different jobs, and it's worth knowing which to reach for. The File Manager is for
individual samples: adding, downloading and deleting sounds slot by slot. Backup & Restore is for
whole snapshots: it saves a single project as a .ppak file, or the whole device as a .pak
file.
For day-to-day housekeeping, use the File Manager. Before a gig or a firmware update, take a full backup as well. It pairs nicely with an organised off-device project library.
