The app is an AudioUnit AUv3 plug-in embedded in a "container" app. The app is only needed to register the plug-in inside the system. After starting the app once, the plug-in can be used in any audio software! This procedure is a bit confusing because there is nothing else happen, but it's Apple's intended way of installing an AUv3 plug-in! The included song is just a little "pre-view" to evaluate the function, because normally there is nothing happen as explained above :) This all is explained in a text that is shown in the app - please also note my help video here: https://www.youtube.com/watch?v=mu-l-2Eqhyo I would kindly ask you to adjust the review again as the plug-in works well! Thanks! ### 3/5 — Works, BUT... *2021-08-25* I mixed down a track of hand claps with the claps panned hard right and left, forgetting how unnatural that sounds on headphones, but had deleted the original clap tracks. So I found this app, and it works. BUT. It resets every time you close and open a session in GarageBand. Presets don’t work either. I haven’t tried closing a session and doing a mixdown to see if the effect is intact on the full mix, but I assume it isn’t. Which means you are forced to merge your track within the session with the effect on in order for it to keep any changes you made, which is a big problem. I see one other person here has had the same problem and it hasn’t been fixed. The plug-in works great in a session, exactly what I needed, but losing the changes every time you close out a session is obviously not ideal. **Developer response:** Thanks for your feedback! I have to apologies for the delay in answering - I rarely check comments here - better use the contact link inside the app to get in contact. I understand the problem and instantly fixed it in version 1.2 - now the settings will be saved. Thanks for your help to improve the app!!! ### 4/5 — Help needed *2020-11-06* Let me start by saying I love the app and am grateful for it’s existence. The one problem I have is that when used on a project and I close the project, it resets. This has happened so often I end up having to check multiple times to make sure it stays on the settings. Please help and release an update soon if possible. **Developer response:** Thanks for your feedback!

Joerg ### 5/5 — It’s free and it works. What more could you want? *2020-04-18* This is a life-saver since Cubasis 3 somehow lacks the ability to make a track mono. **Developer response:** Thank you so much for the feedback!
