Re: Raspberry Pi random music composer

I still have, somewhere, a number of BBC computer programs, typed in from Acorn User magazine, where one set of Data statements (representing the pitch and duration of each note of the theme) were played, and then played again a bar (or some other time interval) later, at the same or at a different...

Re: first note of music file via HDMI is missing

I could perhaps add a very quiet note before the midi tune starts to try and kick the audio into action, but this would probably be equally obje...
