This will be 5 star when it will add a reset button also when fixed the sound crash what happens sometimes and i have to close the app and reopen to get sound thanks
The sounds are on the better side of...

Decent! The sounds are the potential of this app but the controls make it extremely unintuitive. One has to go to the far ends of creativity to use this app...such as having a way to record the sounds a then creating a software instrument in another app using the sounds. That process would be too tedious. This app could be so much better and really opened up with improved controls. For example, add midi in for better keyboard control of the sounds. Add a settings button that offers playability options such as turning on background audio so that the app can play in the background. These options would easily take the app from low to high ratings.
Oh wow, you actually make this app only for iOS 26 users only a music app tons of features

Totally unusable product! you'd be repenting your decision later after clicking the purchase button. hope it'd save somebody, and don't have to go through this nightmare of an app. Worthless waste of an app from a very genius developer. I wish they Could’ve Learned from Audiothing, Bram Bos, OSC, 4pockets, Bleass, these giants. It’ll always be a wastage of an app, save your bucks!What are you try to become apple, The most materialistic lustful corporation, Totally ravaged the dream Steve Jobsstarted Apple with.
