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 two things it doesn’t.

  • 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 is coming to iPhone and iPad with version 1.6, with the Fast splitter pack (see Stem Splitter). Everything else travels.

The obvious one: you can tweak a kit or prep a few samples on the sofa, on the train, or in the studio without lugging a laptop about. Connect the EP, 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, with a Pro trial included. The Core Sample Editor is free forever; managing the device is part of Pro.
