problem with while loop using getch function

Hey guys
I'm writting a program that is supposed to play music and i'm having difficulty with turning the music on/off.

To start the music the user has the press the O key, and to turn it off they press the M key, using on_off = getch(). The music is played by using the random function to select a midi_note, and then looped using the while loop.

I can get the O button to start the loop, but then can't get the m button to stop it. I'm assuming this is because getch has already assigned O to the on_off.

Is there a way around this? Sorry, but i'm a bit of a n00b when it comes to programming

Thanks :)

Without seeing what your code looks like, it will be almost impossible to answer.

Try getche() and see the pressed key, it should print O, M or whatever, if not then the bug prolly is in previous line
