Tutorials

Section titled “Tutorials”
  • How to Auto-Sample a Synth for the EP-40 with EP-PatchStudio. Sampling a synth note by note is slow. EP-PatchStudio’s Auto-Sampler does it for you: point it at a hardware synth or a VST, set the range, and it sends the MIDI and records each note automatically. Here’s the full setup.
  • How to Back Up and Restore Your EP Device. Take a proper backup of your EP-40, EP-133 or EP-1320 before a firmware update, a big reorganisation, or just for peace of mind. Here’s how the three backup scopes work in EP-PatchStudio, and how restoring works.
  • How to Back Up Your EP from Your Phone Before a Gig. No laptop at the venue? No problem. EP-PatchStudio runs on your phone, so you can take a full backup of your EP-40, EP-133 or EP-1320 from your pocket before you play, with the device on USB.
  • How to Fit More Samples on Your EP-133 K.O. II (the 128 MB Limit). The EP-133 K.O. II holds 128 MB of samples across 999 slots. When you start running out, you don’t have to delete sounds, you can optimise them. Here’s how to fit more onto the device with the Batch Processor.
  • How to Get a Lo-Fi, Crunchy Sound on Your EP Device. Clean samples too polished? Bake some grit in before you upload. Here’s how to use EP-PatchStudio’s Batch Processor to give your samples that lo-fi, crunchy, vintage-sampler character for boom-bap, dub, chiptune and beyond.
  • How to Make EP-40 Multisamples on Your iPad. You can build EP-40 multisamples on an iPad, not just a computer. Import your samples, map them across the keyboard with your fingers, and send the patch to the device over USB.
  • How to Make Multisamples for the EP-40 Riddim. A step-by-step guide to building your own multisamples for the EP-40 Riddim: map samples across the keyboard, set root notes and zones, and send the patch straight to the device.
  • 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.
  • 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.
  • How to Manage Your EP Device Samples from an iPad or iPhone. EP-PatchStudio isn’t just a desktop app. It runs on iPhone and iPad too, so you can manage samples, build multisamples and back up your EP-40, EP-133 or EP-1320 from the sofa, with the device on USB.
  • How to Manage Your EP Sampler from an Android Phone. EP-PatchStudio runs on Android, so you can manage samples, build kits and multisamples and back up your EP-40, EP-133 or EP-1320 from your phone, with the device on USB. Here’s how to get set up.
  • Multisampling a Bass (or Guitar) for the EP-40 Riddim. A sampled bass that plays evenly across the keyboard is one of the most useful instruments you can build for the EP-40. Here’s how to do it so it stays deep and in tune, low notes and all. The same approach works for guitar.
  • Multisampling a Real Piano for the EP-40 Riddim. A piano has 88 keys. An EP-40 multisample has eight zones. Here’s how to choose which notes to sample, where to place them, and how to handle a piano’s long decay so it plays convincingly across the keyboard.
  • Multisampling a Synth for the EP-40 Riddim. Synths are the easiest thing to multisample well. They hold forever and stay consistent across the keyboard, so the only real skill is good loops. Here’s how to capture a hardware or software synth for the EP-40.
  • Trim and Tidy Your Samples Without Opening a DAW. You don’t need to fire up Ableton just to top-and-tail a sample. EP-PatchStudio’s Sample Editor lets you trim, set loop points, level and choose the play mode for a sample, then send it straight to your EP device.

Workflows

Explainers

Section titled “Explainers”
  • Importing a Demucs-compatible Model. Stem Splitter separates a song into stems on your own computer using a model file you supply. No model is included, hosted or downloaded by the app. Here is how to import a compatible one and what the app can load.
  • Root Notes and Key Zones on the EP-40, Explained. Two settings do all the work in an EP-40 multisample: the root note and the key zone. Understand both and your custom instruments will play in tune across the whole keyboard.
  • What the Device Info Dashboard Tells You About Your EP. Plug in your EP and the Device Info dashboard is the first thing you see: storage, firmware, backup health and quick links to every tool, all on one screen. Here’s how to read it.
  • Why EP Multisamples Don’t Use Velocity Layers. Big software samplers stack soft, medium and hard recordings on every key. EP multisamples don’t. They map one sample per zone, by pitch. Here’s what that means when you’re building sounds for the EP-40.

Troubleshooting

  • EP Device Not Showing Up Over USB? Here’s the Fix. Plugged your EP-40, EP-133 or EP-1320 into your computer and nothing’s connecting? Nine times out of ten it’s one of a handful of simple things. Here’s the checklist, in the order worth trying.
  • Fixing Detuned or Clicking EP-40 Multisamples. Two problems spoil more EP-40 multisamples than anything else: notes that play out of tune, and clicks in sustained sounds. Both have simple causes and quick fixes. Here’s how to track each one down.
