Hey, I have just configured the entire piano project, everything works perfectly I am delighted!
Today, I would like to add a functionality, it is to modify the tempo of a piano piece using the web interface directly. Indeed, we can do this from the small OLED screen, so I would like to know if I can retrieve the variable from the python program to call it in the html page and let the user modify his piano tempo to play more or less fast.
I will add the speed modes in the web interface directly with the attributes : slow(25%) / medium(50%) / fast(75%) / hard(100%). All this by changing the tempo percentage which is 100% at the beginning.
I saw that there was the function "set_tempo" or "song_tempo" present in the file "learnmidi.py".

self.set_tempo = 100 or self.song_tempo = 500000 or self.ticks_per_beat = 240

In my new page named "songspead.html" and added in the menu, I added the four options in the list like this : <option value="0">Slow</option> <option value="0">Medium</option> <option value="0">Fast</option> <option value="0">Hard</option>

Do you think it would be possible?
Thanks for your help!
