Mainly I find that it has great difficulty instantiating in BM3 when loading saved projects. I would say my success rate is about 25%. In other hosts, it is maybe 50%. I am running an M1 iPP, for reference. Otherwise, when it does load it is very fun and useful for the price! ### 4/5 — Issue after iOS update *2021-03-17* Hi Marek, I love what this app does, however since updating to iOS 14.4.1, Koala FX won’t open in GarageBand! I’m definitely not blaming the app....I always have regrets anytime I update my OS. ### 5/5 — Very useful *2021-01-06* Instantly transforms anything running in a DAW. Would love to have it also as an IAA fx. ### 5/5 — Mind readers *2020-12-10* Their sampler and this FX plug-in is everything I’ve wanted and didn’t know existed Easy workflow Distinct sound The keyboard w ready FX makes this good enough to be a synth plug-in Bigger keyboard maybe is all I’d ask but I understand that’s not the focus of K FX ### 5/5 — Au Renoir 404 *2020-10-19* I have been working for couple of weeks now with this app in the Aum environment with zero glitches , hang ups, crashes or other problems ...and so it definitely has found a regular home in my studio and work flow...it pays its way all for the price a Chicken Foo Yung and a cheap can of larger. It’s definitely worth reading the manual and viewing the various tutorials , on YTB, to get some mastery of the app...and having done so I will be selling my 404 for the price of a good weekend out ...no more timing errors..no more convoluted multi button presses to achieve a simplicity.. Best Limbic 🎩🎩🎩🦄🎹 ### 5/5 — Why do you need more basic FX? *2020-10-04* Because there are 16 of them, you can put them in any order you want, construct 8 different sets of them and morph between these by dragging the x-y cursor or just get Rozeta LFO to take control of that, spark up (optional) and enjoy, knowing that all this very simple, hugely enjoyable ride cost you was less than the price of a sandwich with a named salad leaf. ### 5/5 — Yes *2020-09-18* After using Koala Sampler for a couple of months , I thought I’d give this a go for use in other production suites & Daws. Fantastic selection to get tracks finished of with such an intuitive method ### 4/5 — It’s okay *2020-08-15, version 1.0* Could be better.The reverse effect doesn’t seem to be working.Please fix. ### 3/5 — Could be great *2020-08-07* FairPlay it’s cheap, simple to use and gives a fair degree of instant gratification but it desperately needs a wet/dry knob for each effect, some smash you in the face as soon as you engage them and others seem barely audible like the reverse.. 3 stars because it promising but doesn’t really deliver imho, hopefully it’ll get some spit and polish.. ## Most critical reviews (10 lowest-rated) ### 1/5 — Не работает приложение *2025-08-16* Как вернуть деньги ???! ### 1/5 — CRASHES IN LOGIC PRO FOR IPAD *2023-05-31* I initially used this to apply live effects to a track, in Logic Pro for iPad. While the first tracks worked, after crashing once, I haven’t been able to use Koala fx with Logic since. Whenever I load the audio unit, I’m either: 1) given an error notification, or 2) koala loads, and the crashes, as soon as I attempt to playback, or record a track. ### 1/5 — Midi mapping *2022-01-05* I gave the 4 star still you are not responded me on any platform face book Instagram and here too now I am giving 1 star only because I am not using it because of no midi support for tweaking nob as we can do in kola sampler If you add midi support I will change the review and rate Hello where is MIDI mapping like kola sampler please add on ### 1/5 — RIP-OFF *2021-04-04* It will not open in GarageBand. So they steal your money and give you nothing. Seeking refund. ### 1/5 — Shame *2020-08-09* Pity it’s not working properly in GB...... lock up the whole screen. ### 2/5 — I really want to like it *2023-05-24* I love Koala, so naturally I decided to buy the effects plug in to use in GarageBand/ Logic Pro iPad. But, no matter how many times I reinstall it never shows up in either program. I tried to look online to see if it was a common issue but I’m the only one with this issue i guess. Regards, - Henry J ### 2/5 — Unusable in Lumafusion *2021-10-08* As a plugin this is unusable in any way within lumafusion which makes me sad. ### 3/5 — Great when its stable *2023-06-25* Crashes anytime I save some work and have to restart my DAW for it to work again but definitely adds a good layer to sounds ### 3/5 — Sounds Great, No Automation in Logic. *2022-11-09* Perhaps, I’m being harsh with two stars, but I literally only bought this to use in Logic. Of course, that was before being cognizant of “for iOS” moniker. Without being able to automate it though, this things kinda useless. Very convoluted, this whole AUv3 thing seems. ### 3/5 — Love the program, it rarely works *2022-10-20* Every single time i want to use it i have to close and reopen garageband several times, and this happens on multiple devices ## Most praised reviews (10 highest-rated) ### 5/5 — Good Tool! *2025-12-22* Much fun ### 5/5 — unterschätzt *2025-10-13* aber geil. ein moster! cool wäre, wenn man bei den fx auch unter der motorhaube bissl schrauben könnte. aber aber aber - einfach hammerlissimo! ### 5/5 — Great dj style multi effect unit *2024-11-26* It’s a must, the same effects as on koala sampler, but now you can use the effects on other apps ### 5/5 — Awesome FX’s!!! *2024-03-14* This are the same amazing effects that you can find on the Koala Sampler app and some awesome tweaking options as well. This developer as proved over and over his commitment to make good quality and reliable apps to have fun while making music! ### 5/5 — Awesome Update *2023-11-12* The new mixer and fx are ridiculous. Akai should hire you ! If you have an SP404mk2 pair it with Koala! ### 5/5 — Au top *2023-09-25* Les effets sont tops et s’intègrent nickel dans Loopy pro ou autres daw en Auv3. Serait-il possible de rajouter les derniers effets rajoutés dans le nouveau mixer de Koala? Le compresseur, tap delay, freeverb, sidechain, warble….ce serait énorme… ### 5/5 — For a layer of grime... *2022-08-04* UPDATE - still a great app in 2022! ...this gets added to just about everything I do! Great sounding and easy to use. Just what I want out of an fx app! ### 5/5 — If you love koala… *2021-12-06* If you love koala and you love the ease and fun of the performance fx and you use any other DAWs or apps, this is a no-brainer. It’s great and all to have individual fx AUv3s for certain things, and sometimes you have to really dig in with parameters, and then sometimes you just need multi-fx quick and easy. That’s what this is for. I put this on my master channel, I put this on individual channels, call this franks red hot because I put that **** on everything. I have other fx and multi-fx apps, but this one is my meat and potatoes. It’s not only great for doing SP-404/Koala style live fx, it’s also great for sound design. Sometimes I’ll turn hold on and just go wild with with a couple different fx, resampling the result, and then using that as a whole new sound in my project. Absolutely worth the money! ### 5/5 — Best fx ! *2021-01-29* So nice to be able to use Koala Sampler’s effects in other music apps! ### 5/5 — i dig it! *2021-01-20* Yah. Nice stuff! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
