What's New in NuRack Auv3 FX Processor

1.52

April 29, 2026

1.52 B74 Added a fix to prevent a crash when switching to Interfave Builder mode (with certain modules like strummer). The issue was caused by a function that silently failed in previous versions of iOS.

#1 fx on App Store

Preface: This app is potentially life changing..

Thank you for making this. An all in one fx rack that essentially replaces any others I use, save for a few specific ones. Minor learning curve (if you don’t watch any tutorials). Everything’s super self explanatory except for deleting modules and routing- still easy to figure out though..
The ability to customize makes effects freaks like me salivate 😌. Being able to split sound in so many ways: L / R, Frequency range, etc. gives you the power to manipulate sound to a degree that would blow the mind of a sound engineer of the past.

I have two things I would like the crew that made this to see.
1. I ask for one more time based effect. ¡A straight reverse reverb! I love the reverse delay, and use it alll the time, but often I just want the tail to be reversed and play at the same time. I have achieved something close to it playing with routing, blend, and the rev. delay + regular reverb, but it makes my brain tired.
2. Sometimes adding a module will just crash the whole rack, and sometimes other racks that are being used at the same time. I do have a slightly older iPhone, but it happens quite often. Especially with the reverse reverb. This phenomena and other random bugs that cause crashes can be frustrating. And SCARY too! Middle of the night, you’re making a lush and gentle ambient instrumental. All of a sudden you hear clicking and popping, feedback, and explosions in your ears at like 100db. Let me know if you’d like more on my feedback, I’d love to talk to developers about this amazing app. The crashing, and the crashing being physically painful sometimes is the only thing holding this back from 100% perfection.

With that being said, I can’t ask for 100% perfection. Especially at the unbelievable price point.

One of my favorite purchases of all time.
The quality of sound, variety of features, customization, and usability is well worth the price. A multi effects vst for the pc on this level would be $300+.

Huge thank you to the developers, from the bottom of my heart. As a broke 22yr old with a burning passion for music and sound..
I’m so blessed to be able to acquire top of the line tools and still be able to eat, pay rent, etc.
Thank you thank you thank you!!!

P.S.:
My most used Preset I’ve made:
Splitter: {Rev. Delay + Reverb}
{tape delay + harmonizer or vocal doubler} Send both to mixer, pan them hard in opposite directions.
Not too crazy but it is a potent combo.

Can’t removed placed modules

Hope you don’t want to change any modules location or remove them after place, because it seems you can’t. Kinda breaks any utility for making complex patches as the individual modules are pretty shoddy. Unfortunately, not broken enough to be accepted for a return. Would be zero stars.

Response from developer

To remove a module simply swipe down with two fingers and a popup will appear allowing you to remove the module. This is in the manual and in my YouTube videos. You can also double tap in the module header for more options, including save/load preset and remove module.

This is very cool.

Just starting out using the Ipad for music. I had only the free effects available on the app store, scattered across different auv3's, and of questionable quality and/or abilities. This app gives me every effect I could possibly need and the ability to customize these effects into a single rack, (or multiple racks in series and parallel). ... And, man, can you customize. It has a has a modular toolkit that lets you build all the effects you want, contained in a single effet slot. Mr. Paul knocked it out of the park again.

I wonder, ifPaul were IK Multimedia , the cost would exceed thousands

This is another super fantabulous gift from the hall of famer dev of the Ios. one of the most respected and remarkable developers, and boy did he do justice, hes gonna lay every other devs down.

if you don’t buy it, you’ll definitely depart much early from the production game.

Respect, 4pockets!

we love you!

Useless unless they move the “load/save” button from top left corner

Your “app support” link goes nowhere. I am trying to use this in algoriddim djay app, but since plugins open in windowed mode there is a permanent bar along the top that covers the “load/save” menu button that you put at the very top. That means I can’t save in-djay configurations and can’t load configurations I make directly in your app.

If you move it down a little, or make a long press anywhere open the load/save menu, that would fix it. Unless you do that this effect is quite useless.

Incidentally, it would be great to allow users to open any stand-alone effect they have already purchased instead of being limited to your built-in effects. I already have your multi-band compressor effect which is better than the one included here: I am basically just trying to add an equalizer on top of that.

Thanks
