Type: palindrome :: Pattern a -> Pattern a

The palindrome function applies rev to a pattern every other cycle, so that the pattern alternates between forwards and backwards.

For example this:

d1 $ palindrome $ sound "arpy:0 arpy:1 arpy:2 arpy:3"

... is the same as this:

d1 $ slow 2 $ sound "arpy:0 arpy:1 arpy:2 arpy:3 arpy:3 arpy:2 arpy:1 arpy:0"


... and indeed this:

d1 $ every 2 rev $ sound "arpy:0 arpy:1 arpy:2 arpy:3"
