How to Manage Samples on Your EP-40 Riddim from Your Computer
Browse, upload and download the samples on your EP-40 Riddim from your desktop with EP-PatchStudio's File Manager, working with the EP-40's numbered sample categories instead of squinting at the hardware.
The EP-40 Riddim holds up to 999 samples across 128 MB of memory, organised into numbered categories. You can manage all that from the front panel, but it's slower than from your computer, where you can see every category at once, upload new samples into the right place, and pull sounds off to back them up.
Here's how to do it with EP-PatchStudio's File Manager.
The EP-40's sample categories
Unlike the EP-133's A-D pad groups, the EP-40 organises its 999 slots into numbered categories, each with its own slot range:
- Kicks: 1-99
- Snares: 100-199
- Hi-hats: 200-299
- Percussion: 300-399
- Bass: 400-499
- Melodic: 500-599
- Chords: 600-699
- Vox / FX: 700-799
- Loops: 800-899
EP-PatchStudio's File Manager adapts its category view to your connected device, so on the EP-40 you browse and add samples within these ranges rather than scrolling one long list.
Connect and browse
Plug the EP-40 in with a USB-C data cable (charge-only cables won't carry data) and open EP-PatchStudio. The File Manager loads every sample from the device, grouped by category, so what you see is what's actually on the EP-40.
If the File Manager shows empty slots when you know the device has samples, check the cable and that the device is powered on.
Upload samples to the EP-40
Add your WAV files in the File Manager, dropping each into the category that fits: a kick into the kicks block, a bassline into the 400s, and so on. A sample rate of 44.1 kHz is a safe default, trim the silence off the front so pads trigger tightly, and name your files sensibly before importing.
To prepare a whole folder first, normalising, trimming, or converting sample rate and bit depth, run it through the Batch Processor before uploading.
Download samples to your computer
Pulling sounds off the device is the reverse: select what you want and download it. Useful for backing up a sound you might want again, or pulling a recording into your DAW. As ever, download anything important before you delete it.
Tidy up safely
When you delete a sample in EP-PatchStudio it goes to the Recycle Bin rather than vanishing immediately, so a mistaken delete can be undone. Treat the Bin as a short-term safety net, not a backup. Keep real copies of anything you care about, and for a full snapshot before a gig or firmware update, take a proper device backup too.
Making melodic instruments?
The categories above are for individual samples. If you want a playable instrument mapped across the keyboard, keys, bass or a lead, that's a multisample, which is its own workflow: How to Make Multisamples for the EP-40 Riddim.
