Then you can fall back to regular Haskell function arguments.

If there is a uniform internal data structure like Binary or String, you
do not even need a new record type per UGen. If a record is the right
internal structure you might compose records on the fly from bricks like
this:
data Freq more = Freq Double more
data Phase more = Phase Double more
data Empty = Empty
type Osc = Freq (Phase Empty)
