Thanks Ray

It freezes on Arch Linux after the last update lol....


I'll try to recompile it next week...


It should be ok now. :)


Can any sounds generated be exported?

yes, you should be able to export generated sounds as .wav just pressing the Export button. Did you try it?

Great tool!

Thank you! Enjoy it! :D

I'd be happy to pay few bucks for Linux version :)


Uploaded! ;)

Thank you <3 I love the dark theme :)


Can you make this available for Linux?

Hi! Sorry, don't have a Linux system right now but you can compile it yourself from source.

Required dependencies are minimum: raylib, raygui, tinyfiledialogs.

If I can compile it myself at some point, I'll upload it.
