quickthresh
Fast chord detection
Description
Combines numbers when they are received close together. quickthresh is a faster, low-latency alternative to thresh that is optimized for chord detection.
Arguments
threshold[number]ms
optional
The base threshold time in milliseconds; all notes received within this time period The default value for the base threshold is 40 ms.
fudge[number]ms
optional
The "fudge" time in milliseconds - if any notes are played within this amount of time at the end of the base thresh time, the threshold is extended. If not provided, the default value is 10 ms.
extension[number]ms
optional
The thresh extension time in milliseconds. This is an additional time frame added to the first argument, if necessary, in order to capture additional notes (due to sloppy playing) into the list. The default value is 20 ms.
Attributes
Common Box Attributes
annotation[symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background[int]: 0
Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.
color[4 floats]
Sets the color for the object box outline.
fontface[int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname[symbol]
Sets the object's font.
fontsize[float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'
hint[symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.
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]
write-only
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size[2 floats]
write-only
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor[4 floats]
Sets the color for the object's text in RGBA format.
textjustification[int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
varname[symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.
Messages
bang
bang will reset quickthresh and output the notes in its buffer.
int
The incoming values which appear within a certain time threshold are stored and output as a list. See the argument descriptions to learn how the time thresholding works.
- input
[int]
(inlet1)
Sets the millisecond value for the base thresh time. All values received in the left inlet within this time period are collected into a list.
- threshold
[int]
(inlet2)
Sets the "fudge" time in milliseconds. If there are any incoming values within this amount of time at the end of the base thresh time, the threshold is extended to allow more values to be added to the list.
- fudge
[int]
(inlet3)
In fourth inlet: Sets the threshold extension in milliseconds. This is an extension of the base thresh time, which is used if values arrive in the object's inlet in the "fudge" time zone.
- extension
[int]
float
In left inlet: The incoming values which appear within a certain time threshold are stored and output as a list. See the arguments' descriptions to learn how the time thresholding works.
- input
[float]
(inlet1)
In second inlet: Sets the millisecond value for the base thresh time. All values received in the left inlet within this time period are collected into a list.
- threshold
[float]
(inlet2)
In third inlet: Sets the "fudge" time in milliseconds. If there are any incoming values within this amount of time at the end of the base thresh time, the threshold is extended to allow more values to be added to the list.
- fudge
[float]
(inlet3)
In fourth inlet: Sets the threshold extension in milliseconds. This is an extension of the base thresh time, which is used if values arrive in the object's inlet in the "fudge" time zone.
- extension
[float]
set
The word set , followed by three millisecond values, can be used to set the three threshold parameter values (base thresh time, "fudge" time and thresh extension).
- threshold
[int]
- fudge
[int]
- extension
[int]
Output
float
When quickthresh has used up its threshold time, any incoming values that were played within the time threshold are output as a list.
