Those words could be chosen differently. In Pd, signal means both of those 
things, as it's a single type of wire and a single type of data; and about 
control... I used to often see the phrase "control object" to mean 
"message-system object"... but I don't recall whether that was in Pd or in 
jMax. In any case I think it would be better to say that the 0-to-1 signal 
is intended as a "multiplicator" or "envelope" whereas the -1-to-1 signal 
is intended as a... non-multiplicator... or non-envelope... you may have 
better ideas for names.
