How to Manage Your EP Device Samples from an iPad or iPhone

You don’t need to be sat at a computer to work on your EP. EP-PatchStudio runs on iPhone and iPad (and Android), so you can manage your EP-40, EP-133 or EP-1320 from wherever you happen to be, with the device connected over USB.

It’s the same app you’d use on the desktop, near enough. Here’s what the mobile version does, and the one thing it doesn’t.

The File Manager, sending to your EP, Backup & Restore and the Stem Splitter are part of Pro. The 14-day trial includes them.

  • An iPhone or iPad with EP-PatchStudio installed (download it free)
  • Your EP-40, EP-133 or EP-1320
  • A USB cable to connect the two

On a Lightning iPhone or iPad, connect your EP through Apple’s Lightning to USB 3 Camera Adapter with its power socket plugged in, then a USB-A to USB-C data cable from the adapter to the EP. Without power, iOS may refuse the connection or drop it. On a USB-C iPhone or iPad, use a USB-C data cable (charge-only cables won’t work). If your EP still doesn’t show up, try the USB checklist.

Pretty much everything. On mobile you can:

  • Browse and manage samples on the device with the File Manager: upload, download, delete and tidy slots.
  • Import audio from your device and trim and edit it in the Sample Editor.
  • Build kits and multisamples for the EP-40, then send them straight to it over USB (sending is part of Pro).
  • Back up your projects so your work is safe before a gig or a firmware update.

If you’ve used EP-PatchStudio on a computer, it all works the way you’d expect, just on a screen you can hold.

The Auto-Sampler needs MIDI and audio routing that only really makes sense on a computer, so it isn’t on the mobile app. If your plan is to auto-sample a hardware synth or a VST, that’s a desktop job. Stem Splitter (part of Pro) isn’t: from version 1.6 it runs on an iPhone or iPad with about 6 GB of memory or more, with the Fast splitter pack (see Stem Splitter). Everything else travels.

You can tweak a kit or prep a few samples on the sofa or on the train without lugging a laptop about. Connect the EP and do your thing, and it’s all on the device when you’re done.

EP-PatchStudio is free to download on iPhone, iPad, Android and desktop, and the Sample Editor stays free. Managing the device, sending to it, backing up and the Stem Splitter are part of Pro, and the 14-day trial includes them.
