i have no idea how this is a 4+ app. i love the idea, was really excited, but the resulting sounds are meh. It often gives me almost the opposite of what i specify; "very low attack" had very high attack, etc. It is still pretty cool but it doesn't deserve 4 stars. Besides, the app overall both looks and feels incomplete; ie, not ready for public distro. if it would at least have tuner knobs or allow to adjust the timbre with another text prompt, it would be close to awesome. But as it is? Meh..

Please include record. And keep working on this! Keyboard speed. Then some tweaks available to given sound, start sharpness and sustain etc, sorry I forget the terms since my synths. Only 2 star thing at the moment but I see the huge possibilities. It saves certain stuff you have used. AI creates different sound if you just enter exact same prompt unfortunately, that's AI. Like AI for internet information, basically makes it up! Correctish half the time. But THIS app could be epic.

Its amazing, specially to get those sounds you dont really know how to make. My only issue would be how robotics it sounds. Even when I ask for choirs, it sounds like a synth, even violins sound like synth. Still, they all work as fine, but closer matchs would be amazing!!
