In left inlet: The zigzag~ object responds to a bang message according to its mode of behavior, which is set using the mode message.

If the zigzag~ object is set to mode 0 or mode 1, a bang message will cause the zigzag~ object to go to the start point (or end point if the direction is negative) and begin outputting values from there.

If the zigzag~ object is set to mode 2, a bang message will cause the zigzag~ object to jump to the next index in the list (or the previous index, if the current direction is negative) and begin outputting values from there.

In left inlet: Converted to float.

In right inlet: Specifies the rate at which the value and time pairs will be output. A value of 1.0 traverses the list forward at normal speed. A playback rate of -1 traverses the list backwards (i.e. in reverse). A value of .5 traverses the linked list at half the normal speed (effectively doubling the delay time values).

(In left inlet: Converted to float.)

In left inlet: Each element in the zigzag~ object's linked list is a pair that consists of a target value (y), followed by a second number that specifies a total amount of time in milliseconds (delta-x). In that amount of time, numbers are output regularly in a line from the current index value to the target value. The list 0 0 3.5 500 10 1000 describes a line which begins with a value of 0 at time 0, rises to a value of 3.5 a half second later, and rises again to a value of 10 in 1 second.

In right inlet: Specifies the rate at which the value and time pairs will be output. A value of 1.0 traverses the list forward at normal speed. A playback rate of -1 traverses the list backwards (i.e. in reverse). A value of .5 traverses the linked list at half the normal speed (effectively doubling the delay time values).

Sets and triggers a function as (value) (ramp-time) pairs to define points in a ramp. Sending a list message will immediately trigger the ramp.

The word append, followed by a list, will add new (value) (ramp-time) pairs to the end of the current list. Sending an append message will immediately trigger a ramp only made of the new points.

In left inlet: The word bangdelta, followed by a float or int, specifies the time over which the transition between values occurs when the zigzag~ object receives a bang. The default is 0 (i.e., and immediate transition).

In left inlet: The word bound, followed by two numbers which specify start and end indices (where 0 is the first element), sets the start and end points of the zigzag~ object's linked list.

In left inlet: The word delete, followed by an int which specifies a position (where 0 is the first element), will delete the value and time pair associated with that index from the list. A list can follow the delete message if you want to remove multiple event pairs from the list. The message delete 0 will remove the current first value and time pair from the list; the second value and time pair (i.e. the value and time pair at index 1) will now become the first values in the list.

In left inlet: The word dump will cause a list consisting of all currently stored value and time pairs in the form

index value delta-x

to be sent out the zigzag~ object's 3rd outlet.

In left inlet: The word end, followed by an int which specifies a position (where 0 is the first element), sets the point at which the zigzag~ object ceases its output when triggered by a bang.

In left inlet: The word insert, followed by an int which specifies a position (where 0 is the first element) and a list, will insert new event pair(s) before the index specified. The message insert 0 5 500 will create a new first entry in the linked list (at the 0 index) with a value of 5 and a time of 500 milliseconds.

In left inlet: The word jump, followed by an int which specifies a position (where 0 is the first element), skips to that point in the linked list and begins outputting value and time pairs from that point. An optional int can be used to specify the time, in milliseconds, over which the transition to the next value will occur (the default value is 0).

In left inlet: The word jumpend causes the zigzag~ object to immediately jump forward to the last value (y)on the linked list.

In left inlet: The word jumpstart causes the zigzag~ object to immediately jump to the first value (y)on the linked list and then output the currently selected list or selected portion of the list.

The word line followed by a list of breakpoints in line~ format (as output by the function object) defines a ramp for zigzag~. The list should consist of alternating value, time pairs.

In left inlet: The word next skips to the next value and time pair in the linked list. An optional int can be used to specify the time over which the transition to the next value will occur (the default value is 0).

In left inlet: The word prev skips to the previous value and time pair in the linked list. An optional int can be used to specify the time over which the transition to the previous value will occur (the default value is 0).

In left inlet: The word print causes the current status and contents of the zigzag~ object to be printed out in the Max Console. The output consists of the current mode, loopmode, the start, end, and loop length of the current list, the pendulum state, and moving value of the object, followed by a listing of each index in the linked list, along with its y and delta-x values.

In left inlet: The word ramptime, followed by a number, sets the ramp time, in milliseconds, at which the output signal will arrive at the target value.

Prepending the word set to user-defined value and ramptime messages allows for setting zigzag~ ramps without triggering playback.

In left inlet: The word setindex, followed by an int which specifies a position (where 0 is the first element) and a pair of floats, sets the target value (y) and transition time amounts (delta-x) for the specified position in the list.

The word setline followed by a list of breakpoints in line~ format (as output by the function object) defines a ramp for zigzag~ without triggering it. In order to trigger the ramp, a bang needs to be sent to the first inlet. The list should consist of alternating value, time pairs.

In left inlet: The zigzag~ object responds to signal values according to its mode of behavior, which is set using the mode message.
If the zigzag~ object is set to mode 0, the current index of the list is determined by the input signal value; any previously set speed, loopmode, start, and end messages will be ignored.
If a signal is connected to the left inlet of the zigzag~ object in mode 1, the input signal functions as a trigger signal; when the slope of the input signal changes from non-negative to negative, the object will be re-triggered as though a bang were received.
If a signal is connected to the left inlet of the zigzag~ object in mode 2, the input signal functions as a trigger signal; when the slope of the input signal changes from non-negative to negative, the object will be re-triggered as though a bang were received.

In right inlet: A signal value specifies the rate at which the value and time pairs will be output. A value of 1.0 traverses the list forward at normal speed. A playback rate of -1 traverses the list backwards (i.e. in reverse). A signal value of .5 traverses the linked list at half the normal speed (effectively doubling the delay time values). The value of the input signal is sampled once per input vector. Therefore, any periodic frequency modulation with a period which is greater than the current sample rate/(2*vector_size) will alias.

In left inlet: The word skip, followed by a positive or negative number, will skip the specified number of indices in the zigzag~ object's linked list. Positive number values skip forward, and negative values skip backward. An optional integer can be used to specify the time over which the transition to the next or previous value will occur (the default value is 0).

In left inlet: The word speed, followed by a positive or negative floating-point number, specifies the rate at which the value and time pairs will be output. The message speed 1.0 traverses the list forward at normal speed, speed -1 traverses the list backwards, speed .5 traverses the linked list at half the normal speed (effectively doubling the delay time values).

In left inlet: The word start, followed by an int which specifies a position (where 0 is the first element), sets the point at which the zigzag~ object begins its output when triggered by a bang.

Sending the stop message causes the ramp to stop at the current position.
