The problem is that I am never satisfied at the first try so then I have to recompile the project several times...
With this script, you get (in test mode, only launched from the editor) a test window for the tones in real time.
The key to hide/show the window is F3 by default, you can change it in the Tint_Config module, simpy by editing the KEY value.
I hope this script will be useful!
