mc.line~
Description
Use the line~ object to generate a signal ramp or envelope. It uses the Max time format syntax; envelope times can be either single valued fixed or tempo-relative.
Arguments
initial-value [float or int]
Optional
Sets an initial value for the signal output. The default value is
.Attributes
maxpoints [int]
Specify the maximum number of user defined points allowed in the line. The default is 129 points.

Arguments
target-value/delta-time
[int]
In left inlet: The number is the target value, to be arrived at in the time specified by the number in the right inlet. If no time has been specified since the last target value, the time is considered to be 0 and the output signal jumps immediately to the target value.
In right inlet: The number is the time, in milliseconds, in which the output signal will arrive at the target value.
In right inlet: The number is the time, in milliseconds, in which the output signal will arrive at the target value.

list
Arguments
target-value
[float]
delta-time [number]
delta-time [number]
In left inlet: The first number specifies a target value and the second number specifies a total amount of time (in milliseconds) in which line~ should reach the target value. In the specified amount of time, line~ generates a ramp signal from its current value to the target value.
line~ accepts up to 128 target-time pairs in a list, to generate compound ramps. (An example would be , which would go from the current value to 0 in a second, then to 1 in a second.) Once one of the ramps has reached its target value, the next one starts. A subsequent , , or in the left inlet clears all ramps yet to be generated.
In right inlet: A list may be used to specify time in one of the Max time formats.

pause
In left inlet: Pauses the internal ramp but does not change the target value nor clear pending target-time pairs. line~ will continue outputting whatever value was its current value when the message was received, until either it receives a message or until a new ramp is input.
resume
In left inlet: Resumes the internal ramp and subsequent pending target-time pairs if the line~ object was paused as a result of the message.
stop
In left inlet: Stops the internal ramp and clears pending target-time pairs. line~ will continue outputting whatever value was its current value when the message was received, resetting its target value to that value.

Output
bang
Out right outlet: When line~ has finished generating all of its ramps, is sent out.
signal
Out left outlet: The current target value, or a ramp moving toward the target value according to the currently stored value and the target time.
