EP-PatchStudio (for EP-133/40/1320) — Stop managing samples. Start making music

Hey everyone,

I’ve been building something I’m really excited to share, it’s not ready just yet but should launch soon — EP-PatchStudio, a native desktop app for EP-40, EP-133 and EP-1320.

The short version: it gives you your time back.


The Problem

We all know the pain:

  • TE’s EP Sample Tool is slow and clunky at times and is online only
  • Creating multisamples means juggling multiple apps
  • Sampling a synth properly takes forever
  • Backups are a nightmare

I got tired of spending more time on admin than making music. So I built the fix.


The New Workflow

Got samples? → Drag and drop into EP-PatchStudio → Zones auto-map from metadata/filenames → Click “Send to Device” → Done. Less than 2 minutes.

Don’t have samples? → Connect your synth via MIDI → Set note range, click Record → It plays, records, trims and maps everything automatically → Click “Send to Device” → Done. 5 minutes.

No more 45-minute workflows. No more bouncing between apps.

I built this for myself because the current workflow was driving me nuts. If you’ve felt the same frustration, this is for you.

Happy to answer any questions.

Way to go!

So, about that DRM and authorisation question. Can you clarify please?

1 Like

Sure. I’m using LemonSqueezy for payments and their license API.

You’ll get a license key when you purchase. Enter it once to activate and you’re done. It’ll do a quick online validation on first activation, but after that the app works offline.

I’m not interested in punishing legitimate customers with intrusive copy protection. If someone really wants to pirate a €49 niche app for Teenage Engineering gear, that’s on them; but I’d rather focus on making the experience smooth for people who actually support the project.

All I need to know, thanks

Thanks. Great questions though. I’ll add them to the FAQ.

A few people have asked about the price and some are comparing it to FPHam’s EP Audio Editor (which is excellent). Sure at the core they can both create multisamples, but EP-PatchStudio does so much more.

I’ve listened to user feedback and I’m changing the app to a freemium model; core sample editing and multisample creation will be free forever but users can pay for an upgrade to unlock everything.

It will basically fully replace the TE EP Sample Tool too and be fully offline with no DRM funkyness. I literally spent months figuring out how the EP Sample Tool communicates with the devices (all legally :smiley:, I’ve also contacted TE on this too). You can create multisamples in less than 2 minutes AND click a button to send them straight to the device without having to export and then load a web browser to transfer them. You can even edit samples directly from the device in the app with all the advanced audio editing tools.

I’m also open to any great feature suggestions from users too. A beta tester asked if there’d be a way to show in the File Manager samples that are currently assigned to projects (or only specific projects) and this way a user can ensure they don’t delete something that’s in use. You can also check a box to protect in use samples from deletion.

I’m really excited to share this with everyone. It’s made me love my EPs again as I spend way less time messing with apps and transferring samples and more time actually making music!

Quick question for the EP community here:

What’s the most frustrating part of your EP workflow right now?

I’m putting the final touches on EP-PatchStudio before launch (Feb 10) and I want to make sure it solves real problems, not just the ones I’ve experienced.

For me, it was spending hours manually creating multisamples. That’s why I built the auto-sampling tool in too.

But what’s slowing you down? Sample management? Normalisation? Organisation? Something else entirely?

Cheers

  • batch editing. e.g. selecting multiple samples (like 50 of them) and changing the playmode from loop to key, the time mode from off to bar, pitch/amp settings etc…
  • rearranging the (order of) samples
  • quickly editing multisamples. (like: swap sound on pad 2 only, change volume of pad 5 etc…)

Thanks @kostianix. Will definitely take all this into account :love_you_gesture:.

Quick update, just unboxed the Teenage Engineering white mystery box from their Flipped Out calendar and got the KO II and Medieval inside. Immediately tested both with EP-PatchStudio and happy to report they work perfectly.

That means full EP line support confirmed at launch:

  • EP-133
  • EP-1320
  • EP-40

Still on track for Feb 10. Thanks for everyone’s patience and feedback so far.

Finally got around to opening my Teenage Engineering Flipped Out mystery box, with Riddim, KO II and Medieval inside. Perfect timing since I needed more devices to test EP-PatchStudio with beyond just my EP-40. KO II and Medieval work great. Device management, backups, transfers all confirmed.

Based on community feedback, Pro is now pay what you want ($25-79). TE’s Flipped Out pricing inspired the move; felt right for this kind of tool. Same features whether you pay $25, $35, $50 or $79.

Thanks everyone for the support on this. I’ve been getting lots of messages and I appreciate all the feedback.

It’s been a much more difficult process than I originally thought. Supporting macOS, Windows and Linux between development and testing, plus building the website, download and update infrastructure… it’s been manic.

I’ll get there in the end and hope you all enjoy using the tool. The goal is to help you enjoy your EP devices more; concentrate on making music, not managing samples.

Free version is free forever (full sample editor, no time limits). Pro adds device connectivity, auto-sampling from hardware/VSTs and one-click backups.

Edit, launch pushed back, early access starts 24th Feb: https://ep-patch.studio

Automation lanes in the Pattern Visualiser now!

Every fader parameter visible per group. Level, pitch, filters, pan, attack, release, FX send, all of it. See exactly what’s happening across your pattern.

Per-track MIDI export too. Pull individual groups out as separate MIDI tracks straight into your DAW.

Getting closer :fire:

Awesome stuff. Could we be drawing in the lanes? Or applying shapes/curves/LFO patterns!?

In future, yes. Great idea on the LFOs, I didn’t think of that. It’s read only for launch, but I plan to make projects fully editable too.

See the video here where I explain: https://youtu.be/9m6I-lhrKd8

I’m getting really excited for this release.

One question for you. I’ve been thinking about what the best way to make multisample instruments from my Kontakt instruments in Logic, since those samples can’t be easily accessed. Any ideas for the quickest way to go about this?

I’ve already thought of this :grin::grin::grin:.

This was one of the major things I wanted to tackle as I have Arturia V Collection and want to be able to record multisamples from it and other VSTs. I’ve built an Auto-Sampler tool into EP-PatchStudio. I will post a full tutorial video soon, but here’s a quick overview:

Great. Really looking forward to seeing it in action. Also, when you do the video if you could go into your ideas for backing up your creations that would be helpful. I’m guessing I’ll be moving stuff on and off the EP more if I’m building instruments. It would be interesting to see your envisioned workflow.

I’d also love to see some instances of multisampled instruments at different sample rates. That sounds like it could be really interesting.
