rpnout
Description
Format 14-bit MIDI Registered Parameter Number messages to be transmitted using the midiout object.
Discussion
A Registered Parameter message comprises several groups of bytes to specify a 14-bit parameter number (2 groups for the for the most significant byte of the parameter number (MSB) and one for the least significant byte of the parameter number (LSB)), a 14-bit value (2 groups for the MSB and LSB of the value) or a 7-bit delta value (1 group), followed by a Null Function (2 groups) to terminate changes to the parameter.
Arguments
parameter-channel [list]
The initial argument is an initial registered parameter number (in the range 0-16383) to be used in parameter changes messages formatted by nrpnout. registered parameter numbers are automatically limited between 0 and 16383. The parameter number can also be expressed as a symbol formatted 'MSB:LSB' (for instance, '1:0' would specify parameter 128). If there is no controller number specified, the initial controller number is 0.
Following the controller number argument is an initial value for the channel number with which to format control messages. If the channel argument is not present, rpnout initially formats control messages on channel 1. In order for this argument to be used, a controller number argument must precede it. The channel number is clipped to the range 1-16.
Attributes
hires [int] (default: 1)
When enabled, rpnout formats high resolution, 14-bit RPN messages for the provided input. If you know that the parameter you are working with only responds to 7-bit values using the MSB, set hires to 0 to avoid inaccurate output from the object. If the parameter you are working with responds to 'high resolution' 7-bit values using an MSB of 0 and a value in the LSB, this setting will have no effect.
running [int] (default: 0)
If running status is enabled, the status byte of all but the first group of bytes in the formatted RPN messages will be eliminated.
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.
jspainterfile [symbol]
JS Painter File
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 [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.

Arguments
lsb [int]
set
Arguments
The set message also accepts an argument list comprising most signficant byte (MSB) followed by least significant byte (LSB). The 7-bit MSB will be bitshifted and ORd with the 7-bit LSB to specify a 14-bit parameter number. For instance, set 1 0 would specify registered parameter number 128.
The parameter number argument can also be expressed as a symbol formatted 'MSB:LSB'. For instance, set 1:0 would specify registered parameter number 128.
Registered parameter numbers outside of the range 0-16383 will be ignored.
Output
int
When a value is received in the left inlet or 2nd inlet (value or delta), the complete MIDI RPN message is sent out the outlet, byte-by-byte.
