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! ### 4/5 — It’s okay *2023-09-28* This app needs to be updated since a mixer has now been added to Koala Sampler ### 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… ### 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 ### 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. ## Frequently asked questions about Koala FX ### What is Koala FX?
