Will we ever see an update?

Tired of being scared every time I update iOS that this synth will finally have to be archived in my frozen (from iOS 13) iPad. Synth is worth getting an iPad for alone so please, do it for us, I’m sure there’s enough of us out there…Either way, thank you for the years of service!

Sounds amazing.

This synth sounds very good. The sounds are not digital in their character. The user interface is well thought out and straightforward. I wish the keyboard width could be changed. I also hope this app will be updated.

Splendid little 4op FM synth with a great sound

Very simple to use and has that rare quality where all the sounds made seem to work well in the mix. Please, please (pretty please) update for AUV3

It’s okay...

Seems like an okay app, but, not remembering the last preset is annoying and no update in 3 years is a worry.
