This is one of the most incredible things I have ever seen.

We just used this to create all the sounds for our Viroids game.


Many thanks, it's a great tool.

Awesome to see it here on itch!

Too bad it's still hacky for Linux/OSX users to use it.

Yeah I can't use it on the itch app on linux T-T

Great piece of software, thank you for sharing it!
