Hi,
I’m tring to use the the MIDIUSB_buzzer example, but I get the errors regarding the ‘tone and noTone’.
I then found this sketch to implement tones on the Due, and have added it to the MIDIUSB_buzzer sketch, but I still get the same error?;
Hears my current example sketch;

Does anyone know what wourds I should use instead of ‘tone and noTone’, to get this working?
