I had thought to do something similar as you mentioned for blue, but
would have had blue generate the values that would have written to a
global k-sig and the notes would have been written for the tempo
instrument would have been processed by the t-statement itself.  I
think it's good to get the times in an envelope as you mentioned and
have the values processed by t-statement, then have the opcode for
getting the tempo.

Best to save this until after 5.17 though, as it's a bit late now, IMO.
