The ones mentioned above outline a variety of techniques for note generation in both simple and complex manners, as well as details of the filters used to give the various "voices"

At grammar school in the 60's the electronics club started building one for the school, but it was still unfinished when I left from upper 6th

That’s some brill info Ed. Did they ever get it finish or was it scrapped?

My idea is to just have some very basic oscillators forming 2 octaves worth of notes. Do you know if these booklets are available online?

Thanks
