#X text 9 -75 curve~ is similar to line~. It produces a signal that
goes from an initial to target value over a specified number of milliseconds.
However \, it produces non-linear ramps using a piecewise approximation
of an exponential function. You specify the parameter to this exponential
function in the curve~ object's right inlet. Values from 0 to 1 produce
an "exponential" curve when increasing in value and values from -1
to 0 produce a "logarithmic" curve. The closer to 0 the curve parameter
is \, the closer the curve is to a straight line \, and the farther
away the parameter is from 0 \, the steeper the curve. curve~ can also
accept a list of up two or three arguments (the previous curve parameter
is used if there are two arguments) \, or a list with two or more value
\, time \, parameter triples. curve~ is limited to 42 such triples
in a single list. The object's approximation of the exponential becomes
better when the vector size is smaller \, but the object also becomes
more computationally expensive.;
