Next week I am giving a talk at the Peterborough Raspberry Pi Jam, and in the course of preparing for it I discovered that there was a bug which appeared in several of the Musical 12 tone alarm scripts I wrote last year. This occurred in the procedure called getbarlist.
I have amended all the incorrect scripts in the original articles and they should now work fine.
At the same time I have added a new script which plays two parts of the random tunes against each other, written at the same time but not published.
It produces tunes like these:
You can listen to the tune here
All of the corrected scripts and the new addition can be downloaded in a zip file here
Details of how to use them are in the original article series starting here
Here is page 4 of the series containing details of the changes.
