Generates a linear ramp driven by incoming bang messages. It takes a list of breakpoint segments (and the number of events to span) and outputs a smooth ramp between values.
bline is similar to the Max line object, except that it is driven by bang messages sent to its left inlet. This gives the object a flexible timebase, which is useful when working with events that have a variable processing time (such as rendering matrices in Jitter). It works with integer and floating point numbers, can be stopped (with the stop message), and can use multi-segment lists (similar to the MSP line~ object).
Optional. An argument may be used to set the initial value to be stored and the output type for the object--if the first argument is an int, the bline object outputs integer values, and a float will set the bline object to output floating point values. If there is no argument, the initial value is 0 and the output type is int.
Common Box Attributes
Sends a new step in the breakpoint list out the left outlet. If the current list of ramp segments is finished, a bang message will be sent out the right outlet
Sets the bline object to the specified integer value. Any and all pending breakpoint segments are forgotten (i.e. the time is considered 0 and bline outputs the target value when it receives a bang).
Sets the bline object to the specified float value. Any and all pending breakpoint segments are forgotten (i.e. the time is considered 0 and bline outputs the target value when it receives a bang).
The bline object sets breakpoint segment values using lists of data composed of pairs of numbers. The first number in each pair can be either an int or a float specifying a target value, followed by an integer that specifies the number of bang messages that will have to be received before reaching the target value--note that this differs from other Max breakpoint objects like line, which specify a time-to-target value in milliseconds.
Sets the bline object to the specified value. Any and all pending breakpoint segments are forgotten (i.e. the time is considered 0 and bline outputs the target value when it receives a bang).
Stops bline from sending out numbers, until a new list of ramp segments is received.
Out right outlet: When bline has arrived at its target value, bang is sent out.
Out left outlet: Numbers are sent out in response to received bang messages, describing a straight line toward a target value. If a list of breakpoint segments is specified before the line is completed, the new line starts from the most recent output value in order to avoid discontinuities.
If a value is received in the left inlet without an accompanying time value, it is sent out immediately.
