Description
The hostsync~ object provides information about the current state of the ReWire host.
Discussion
Sample count information is available in any host; even Max. The validity of the other information output by the object is dependent upon what synchronization capabilities the ReWire host implements; the value from the flags (10th) outlet tells you what information is valid. Output from hostsync~ is continuous when the scheduler is running. Alternatively, you can bang its inlet to report the current values.
Arguments
None.
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] (default: 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'
hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.
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] (default: 0)
Toggles whether an object ignores mouse clicks in a locked patcher.
patching_rect [4 floats] (default: 0. 0. 100. 0.)
Sets the position and size of the object in the patcher window.
position [2 floats]
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] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 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]
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]
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 [float]
Sets the color for the object's text in RGBA format.
textjustification [int]
Text Justification
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.

Output
float
Out 4nd outlet: The current beat fraction, from 0 to 1.0. If the ReWire host does not support synchronization, there is no output from this outlet.
float
Out 6th outlet: The current tempo in samples per beat. This number can be converted to beats per minute using the following formula: (sampling-rate / samples-per-beat) * 60. If the ReWire host does not support synchronization, there is no output from this outlet.
float
Out 7th outlet: The current number of beats, expressed in 1 PPQ. This number will contain a fractional part between beats. If the ReWire host does not support synchronization, there is no output from this outlet.
int
Out left outlet: 1 if the ReWire host's transport is currently running; 0 if it is stopped or paused.
int
Out 2nd outlet: The current bar count in the ReWire host sequence, starting at 1 for the first bar. If the ReWire host does not support synchronization, there is no output from this outlet.
int
Out 3rd outlet: The current beat count in the ReWire host sequence, starting at 1 for the first beat. If the ReWire host does not support synchronization, there is no output from this outlet.
int
Out 8th outlet: The current sample count, as defined by the ReWire host.
int
Out 10th outlet: A number representing the validity of the other information coming from hostsync~. Mask with the following values to determine if the information from hostsync~ will be valid.
Sample Count Valid 1 (always true)
Beats Valid 2 (2nd, 3rd, 4th, and 7th outlets valid)
Time Signature Valid 4 (5th outlet valid)
Tempo Valid 8 (6th outlet valid)
Transport Valid 16 (left outlet valid)
Loop Info Valid 64 (9th outlet valid)
list
Out 5th outlet: The current time signature as a list containing numerator followed by denominator. For instance, 3/4 time would be output as the list 3 4. If the ReWire host does not support time signature information, there is no output from this outlet.
list
Out 9th outlet: The loop info output as a list of three numbers containing loop on/off state (0,1), the loop start point (in 1PPQ ticks), and the loop stop point (in 1PPQ ticks). For example, if the time signature was 4/4 and looping was on from the start of the fifth measure for four bars the list would be 1 16 32.
