+#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.;
