The CPC+ has an added function for sound - it can automatically set AY registers from a 'script' within memory without the Z80 doing anything (known as DMA - Direct Memory Access)

This means we can play a digital sound without using ANY cpu power - unfortunately the 'script' is quite large, so it takes a lot of memory...
