This is a really comprehensive music making program, a masterpiece of presentation and programming in Basic.
It allows you to input your own creations in standard music notation, play the tune back, store it on tape and even print it out using the ZX Printer.
Although not fully error trapped, it is most impressive, particularly the re-definition of lower case characters as notation.
There is however a strange contradiction in the purpose of this program.
To use it to the full, you need to know standard music notation very well.
If you do, then it's unlikely that you have access to an instrument which sounds much better than a Spectrum, and you could write your music down with a pencil!
If, on the other hand, you are a computer freak who wants to see the sound capability of the Spectrum explored, then you will have to get to grips with the notation before this program is of value
And, in my opinion, standard musical notation is harder to understand than assembly language programming!
