Multisample editor interface showing piano keyboard, sample zones and note mapping

Sound familiar?

Browser-based tools are limiting

Can't work offline. Slow backups. No audio editing. Just basic file transfer. You need more than that.

Multisamples are a nightmare

Three different apps. Manual zone mapping. Hoping the metadata is right. There has to be an easier way.

Sampling synths takes forever

Record a note. Trim. Normalise. Export. Convert. Repeat 8 times. Your afternoon is gone.

The old way vs. the new way

Without EP-PatchStudio

Creating a multisample:

  1. Record each note in your DAW
  2. Export as WAV
  3. Import to an EP multisample editor
  4. Trim silence from each file
  5. Normalise levels
  6. Map zones, edit params
  7. Export samples
  8. Upload to device via TE's EP Sample Tool

Time: 25-30 minutes

Managing your device with TE's EP Sample Tool:

  • Browser-based, can't work offline
  • No multisample editor
  • No audio editing tools
  • Slow backups
With EP-PatchStudio

Creating a multisample:

  1. Drop samples in (zones auto-map from metadata/filenames)
  2. Click "Send to Device"

Done

Time: 2 minutes

Or use the Auto-Sampler:

  1. Connect synth via MIDI
  2. Set note range
  3. Click Record (zones auto-map)
  4. Click "Send to Device"

Done

Time: 5 minutes

Managing your device:

  • Native app, works offline
  • Batch upload/download/delete

Questions?

Is this a subscription?

No. One-time purchase, lifetime updates. You pay once, you own it forever.

Why pay what you want?

I'd rather you use the software than skip it because of price.

Traditional pricing forces everyone into the same box. PWYW lets you pay what feels fair for your situation. Everyone gets identical software—no tiers, no locked features. You own it forever.

The price difference is about supporting development, not unlocking capabilities.

What do I get for paying more?

Everyone gets identical software. Every feature, no limits, owned forever.

The price difference is about supporting development. Here's what the tiers mean:

  • $25 — Full Pro licence. Covers my costs.
  • $35 — What most people pay. Funds future updates.
  • $50 — Early access to beta features.
  • $79 — Priority support, early beta access, roadmap input, optional credits.

Pick what feels fair for your budget.

What's a Superfan?

The $79 tier. You get priority email support, early access to beta features, direct input on the roadmap and your name in the credits if you want it.

It's for people who want closer access and a voice in what gets built next. Everyone gets the same software, but Superfans help shape where it goes.

Does it work with my device?

EP-PatchStudio supports EP-40 Riddim, EP-133 K.O. II and EP-1320 Medieval. Multisample creation and looped samples are EP-40 only (it's the only one that supports the additional modes until TE releases an updated firmware hopefully). Device management works with all three.

What's the difference between this and TE's EP Sample Tool?

TE's EP Sample Tool is browser-based and limited to basic file transfer and backups. EP-PatchStudio is a native app that works offline, with faster one-click backups, a full multisample editor, auto-sampling and pro audio editing tools. It's everything TE's EP Sample Tool does, plus everything it doesn't.

What if I don't like it?

14-day money-back guarantee, no questions asked.

Mac, Windows, Linux?

Yes, yes and yes. One license covers all three platforms.

What if I need help?

Free users can get help via the Discord community. Pro users get email support - I typically respond within 24 hours, often faster. Superfans get priority email support. It's just me, so you're talking to the person who actually built the thing.

Can I export my work?

Yes. You can export multisamples, individual samples, backups - everything. Your work is yours. Nothing is locked into the app.

Is there annoying DRM or copy protection?

Nope. I'm using LemonSqueezy for payments and their license APIs. You'll get a license key via email when you purchase. Enter it once to activate and you're done. It does a quick online check on first activation but after that the app works completely offline.
