Nerdy fun

This is a lot of fun to play with. It’s probably useful if you are into linguistics or phonetics. You can almost make it talk. It would be cool if consonants were added to make this fully possible.

Remove audiobus with no additions come on!

Auv3 please !!!!🙏

Used to be amazing.

iOS needs improvement. App no longer makes any sound.

not working, only makes sound of microphone

it doesnt make any sound and i've tried on my phone and my ipad and ive tapped on both pannels

it also makes a dot in the other panel once every 10 seconds and copied the sound of the microphone making a super high pitched buzz

Broken latest version of iOS?

Doesn't seem to do anything anymore other than try to listen to the mic and cause feedback
