All bets are off with that version.

Also fails in current version.  Write $drumnotes instead of #drumnotes :
it would appear that \repeat does not take unqualified Scheme
expressions as its music argument.

Which is a pity since $drumnotes will cause an unnecessary copy but I
don't see a good way around it right now short of writing the whole
thing completely in Scheme rather than using #{ #} .
