OP-PatchStudio [unofficial] OP-XY tools

[Instant_Fidelity]

I created this tool a while ago, but never shared it here. I hope you all enjoy.

OP-PatchStudio [unofficial]

I’ve been using various other tools for the last while, Digichain, ADSR, Operator-XY and this tool from buba447/zeitgeese, but nothing did exactly what I wanted. Many of them were able to create a basic presets with samples, but then on the XY you had to edit various settings, tuning, loop points, etc., then save as a new preset, but this was saved to snapshots, then you had to use a computer to rename and move the preset… Way too much messing.

So I forked the repo from one of the existing tools and released a beta opxy-tools. But it quickly became too hard to manage (single html with vanilla JavaScript), I then rewrote the entire application in React/TypeScript and added a whole load of new features to make things easier as well as making it look and feel more like a tool for the OP-XY.

Wow! Thanks for this man! =) going to try it out right now

[Instant_Fidelity]

Thanks. Let me know if you have any issues or would like to request any new features too. There’s a Google Form built into one of the tabs.

Just downloaded it, and even before using, I can say that it looks stunning!
I will definitely work it soon, but the level of detail, and care for design, user interface and specificity to the device workflow is truly wonderful to see!
Thank you for making this, and your generosity in sharing it with this community!
Bravo!

[Instant_Fidelity]

Thanks for the feedback. It took absolutely ages to try and get it looking spot on. I even had a calipers out measuring up the actual device to get everything looking .

A lot of the other tools I’ve used before work great, but don’t usually pay the same attention to the design elements. Given TE is a design company first and the XY and Field devices are amazingly designed instruments, I wanted to give OP-PatchStudio some of this feel.

I’ve not released the filters yet as I’ve not quite gotten the look and feel there just yet, but this is coming soon.

This looks awesome great work! Too bad iPadOS Safari doesn’t support WebMIDI, will OP-PatchStudio be able to at least transfer files back and forth?

There is an old app called WEB MIDI but it’s wonky now as it has not been update in years.

So far so good. This is nice. The only thing I might say would be nice to add is on the drum tool allowing to set playmode to group

[Instant_Fidelity]

Thanks for the feedback.

This is in there. On an individual drum sample, go into edit and then on play mode choose mute group.

[prnts]

Ah cool. I didnt spend enough time poking around. So it has to be done per sample. Is it not possible to have it in the dropdown that affects all samples? This is a nice feature for sample based beatmakers

[Instant_Fidelity]

No worries. That’s there too. At the bottom, the bulk edit button becomes active when you have two or more samples loaded to the drum tool.

In there you can change the play mode for all loaded samples and save.

Registered for the forum just to say thank you! This tool is unreal.

[Instant_Fidelity]

Thanks . It’s my first open source tool that I’ve released widely. Currently have over 3k unique visitors per month using this on average, so that’s really cool. I made it open source to share and make available freely, but if anyone finds the tool useful, please support it via Buymeacoffee or Patreon.

Also use the feedback form to let me know what other features you’d like to see added! I’m think about a cloud patch save thing via Google Drive/Dropbox, so your entire OP-PatchStudio preset library is available across devices. There’s a planned companion app in development too that will allow presets to be sent straight to the XY from the webapp. It will also allow users to create backups of their device, etc.

Super job. Thank you.

EP-PatchStudio 0.33.0 beta out now

New release for the EP-PatchStudio desktop app (multisample editor always free, cross-platform, for EP-40 Riddim, EP-133 K.O. II and EP-1320 Medieval).

The main thing in this release is the Batch Processor going to general availability. You can drag in a folder of samples, set your processing options once (normalise, fade, trim silence, resample, sample rate, bit depth) and apply across the lot in one pass. There’s a Sample Editor built into it with full waveform editing, in/out markers, zoom, loop region and per-file overrides all in a single tabbed modal.

The Beta badge stays for one more release. I’d really appreciate feedback while it’s there. If anything feels off or you’d like an option that isn’t there, please open an issue on GitHub or just reply to this thread.

Other notable bits:

- Trim to Sample Markers — new Crop button that destructively trims audio outside your in/out markers, mainly for getting longer recordings under the 20-second TNGE multisample limit

- Auto-Chop in Drum Kit mode — chops now land on the active scale’s kit pad notes instead of a chromatic sequence, so you can slice a loop straight into a playable drum kit on the EP-40

- Drum kit TNGE files now reopen in the Drum Kit layout instead of the melodic keyboard

- Fixed a multisample export bug when switching from Drum Kit to Melodic mode

- Windows microphone permission error in the Auto-Sampler now gives clear guidance instead of a generic input error

Since it comes up: the Sample Editor and Multisample Editor are free forever. No paywall, no time limit. The paid Superfan tier is only for the device management side (file manager, backups, Auto-Sampler). If you just want to build TNGE multisamples for your EP-40, the free version covers you.

Still active development. More on the way.
