accum
An additive accumulator
Description
The object adds to, and then outputs, an internal sum. This occurs at sample-rate, so the sum can grow very large, very fast. The value to be added is specified by either the first inlet or argument. The internal sum can be reset to the minimum by sending a nonzero value to the right-most inlet. The minimum value is 0 by default, but can be changed with the @min attribute. An optional maximum value can be specified with the @max attribute; values will wrap at the maximum.
Constructors
- { arguments={incr}, inlets={reset} }
- { arguments={}, inlets={incr, reset} }
Inlets
incr[float]
amount to add
reset[float]
nonzero reset
Attributes
init[float]: 0
write-only
Specify initial value stored in the accumulator
max[float]:
write-only
Specify optional maximum value. If @max is given, the count will reset to @min whenever it reaches @max.
min[float]: 0
write-only
Specifies the internal count when the reset signal triggers (or the @max value is reached, if @max is specified.)
resetmode[enum]: post
write-only
Specifies whether the count is reset before or after the accumulation. If the mode is 'pre', the count is reset before accumulating the new input. The default is 'post' (after accumulation).
Possible values:
0 = 'pre'
1 = 'post'

patching_rect[4 floats]: 0. 0. 100. 0.
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation[int]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 0. 0. 0. 0.
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect[4 floats]
