### 5/5 — Bester Plugin für Drums ever

*2026-04-13*

Ich produziere verschiedene Musik Richtungen und KNOCK nutze ich bei jeder Produktion um die Drums (Kick, 808, Snare, Clap, Hihat, Percussion..) die gewissen Power zu geben! Es gibt nichts vergleichbares wie KNOCK! Meiner Meinung nach verdient des Plugin ein Preis!

### 2/5 — Doesn’t work in AUM

*2024-11-13*

Was really excited to see what the iOS version would compare the vst and  so far it’s been a real disappointment. I really hope they get it compatible with other apps being an AuV3. And ways doesn’t work on iPhone at all and worked a little bit on one or two apps before crashing or no output of sound when loaded onto tracks/channels.

**Developer response:** Thanks for taking the time to share this, and I completely understand the frustration.

We’ve just released an update that addresses several stability issues and improves AUv3 behavior across supported iOS hosts. If you haven’t already, please update to the latest version and test again.

If you’re still experiencing crashes or no audio output, feel free to reach out to support with the exact host app and iOS version you’re using so we can investigate further. We’re actively working to make KNOCK as stable and seamless as possible across devices.

Appreciate you giving it another shot.

### 1/5 — Doesn’t work in AUM

*2024-11-04*

Was really excited to see this AuV3 plugin on here and not sure if it works or if I’m doing something wrong but I’ve tried it in a few different AuM projects and all the audio cuts out. Dang I hope they get it working. It’s a bummer when it doesn’t work at all with the main application you’re using it with. I will check with other DAWs later like cubasis and NanoStudio on iPhone versions and will attempt again on iPad daws then re-review but so far it’s been a real disappointment

### 4/5 — Plz fix crash logic when exporting

*2024-09-09*

Sick app just need a lil love

**Developer response:** Appreciate that 🙏

We just pushed an update with stability improvements and AUv3 fixes, so make sure you’re on the latest version. More refinements and polish are coming. Thanks for rocking with KNOCK.

### 3/5 — Crashes

*2024-04-11, version 1.0.0*

Keeps on crashing in Logic Pro for iPad come on update it please!.

### 1/5 — Doesn’t reload up

*2023-10-16, version 1.0.0*

App works great but when I load up a song again some of the knock apps are greyed out.

### 1/5 — 20 dollars and it doesnt work well with other apps…

*2023-10-08*

Thats a big bummer KNOCK it would be 10/10 stars if it was compatible with other apps

**Developer response:** KNOCK is AUv3 compatible and works inside supported iOS hosts. We’ve also released updates improving cross-app stability and performance.

Make sure you’re on the latest version, and if there’s a specific app giving you trouble, reach out to support with the app name and iOS version so we can look into it.

### 1/5 — Logic Pro IPadOS

*2023-08-05*

The continual crashing is absolutely frustrating and always run into problems exporting. Why is it that GarageBand can handle this plugin so much better? It crashes but not nearly as much as Logic Pro.
I’ll change my review when this gets resolved because this has gone on long enough. 
Please! An update is an absolute must at this point and if it doesn’t get resolved this plug-in is going down the toilet.

When this app does decide to work it’s honestly great but not great if I can’t even play it for a min before crashing or export it properly to upload.

**Developer response:** We hear you. That level of crashing, especially during export, isn’t acceptable.

We’ve recently released an update focused specifically on AUv3 stability and Logic Pro for iPad behavior. Please make sure both KNOCK and Logic are fully updated.

Logic’s plugin handling differs from GarageBand under the hood, which can expose issues differently, but we’re actively optimizing for Logic since many of you rely on it professionally.

If you’re still seeing crashes after updating, please contact support with your iPad model and iOS version so we can investigate directly. We’re committed to getting this fully stable.

### 5/5 — よい

*2023-06-02*
