I’d been mentioning that it would seem to be a simple program to create music on your computer. Simple enough to include as a free program – like solitaire, or mine sweeper. The old Apple IIs had one tone – that you could modify the duration and frequency of – and that was over 25 years ago. There should be a simple program to allow you to choose notes and let you play simple tunes. I’m not talking ‘ode to joy’ or anything, but you should be able to make a simple ‘jingle bells’ or something.
Maybe there’s one in there somewhere, but I haven’t found it yet.
