#X text 30 28 Here is a related issue: if we use a (control) line object
to change an amplitude \, it sends ramping control messages \, once
every 20 msec by default. At left we use this to control the amplitude
of a sinusoid. In effect we're multiplying the sinusoid by a staircase
signal (50 increments per second.) Using the signal version \, line~
\, fixes the problem. Line~ outputs a ramp that is incremented every
sample.;
