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.

This app's reallllllly cool. I have hundreds of different VST instruments, sounds and patches. Some are amazing, some are mmehh but unless you remember and take the time to write everything down, it's always a chore trying to figure out what sound goes best with what tune. First three sounds I tried out here were famous Yamaha DX7 sounds from popular 80's tunes. They sounded great 👍

I hope it'd be a little bit more immersive I like the fact that we can then use the sounds that we choose like a different octaves but I'd like it to be more music making with recording and layering and possibly and an AI to chat with to get back and forth communication on what sound and song and tone frequency we're going for higher dimensional frequency I'll wait and with excitement to see if this happens or anything
