Multi-channel lookup a data/buffer object (no interpolation)

Description

Multi-channel lookup a data/buffer object (no interpolation). The first argument should be a name of a data or buffer object in the gen patcher. The second argument specifies the number of output channels. The input phase ranges from 0 to 1, and wraps outside this range. The last inlet specifies a channel offset (default 0).

Constructors

  • { arguments={name, channels}, inlets={index, channel_offset} }
  • { arguments={name}, inlets={index, channel_offset} }
  • { arguments={name, channels}, inlets={phase, channel_offset} }
  • { arguments={name}, inlets={phase, channel_offset} }
  • { arguments={name, channels}, inlets={signal, channel_offset} }

  • { arguments={name}, inlets={wave_phase, wave_start, wave_end, channel_offset} }

Inlets

wave_phase[float]

phase to read (between start and end indices)

wave_start[float]

wave start index (samples)

wave_end[float]

wave end index (samples)

channel_offset[int]

channel_offset (zero-based)

index[float]

sample index to read

phase[float]

phase to read (between 0 and 1)

signal[float]

value to lookup (between -1 and 1)

Attributes

boundmode[enum]: ignore
write-only

Handle out-of-range indices: "ignore" returns zero, "wrap" wraps the indices back into the range of the buffer, "fold" and "mirror" wrap the indices back into range by alternating direction, "clip" and "clamp" constrain the indices to the buffer limits. Possible values:

0 = 'clamp'
1 = 'ignore'
2 = 'wrap'
3 = 'clip'
4 = 'fold'
5 = 'mirror'

channelmode[enum]: ignore
write-only

Handle invalid channel indices: "ignore" returns zero, "wrap" wraps the indices back into channels of the buffer, "fold" and "mirror" wrap the indices back into range by alternating direction, "clip" and "clamp" constrain the indices to the channels available. Possible values:

0 = 'clamp'
1 = 'ignore'
2 = 'wrap'
3 = 'clip'
4 = 'fold'
5 = 'mirror'

channels[int]: 1
write-only

Specify the number of channels to read

index[enum]: phase
write-only

Specify how to index the buffer: "samples" indexes by sample offset into the buffer, "phase" converts a signal in the range of 0..1 to span the whole buffer, "lookup" or "signal" converts a signal in the range -1..1 to span the whole buffer, "wave" uses two additional inlets to specify start and end indices of a section of the buffer (in samples), and converts a signal in the range of 0..1 to span this section. Possible values:

0 = 'phase'
1 = 'wave'
2 = 'samples'
3 = 'lookup'
4 = 'signal'

interp[enum]: none
write-only

Specify the interpolation mode: "none" and "step" perform no interpolation, "linear" performs two-point linear interpolation, "cosine" performs two-point cosine interpolation, "cubic" performs four-point cubic interpolation, "spline" performs four-point Catmull-Rom spline interpolation, and "spline6" performs six-point (5th order) B-spline interpolation. Possible values:

0 = 'none'
1 = 'spline6'
2 = 'step'
3 = 'cosine'
4 = 'cubic'
5 = 'fastcubic'
6 = 'linear'
7 = 'spline'

Common Box Attributes

Below is a list of attributes shared by all objects. If you want to change one of these attributes for an object based on the object box, you need to place the word sendbox in front of the attribute name, or use the object's Inspector.

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'

hidden[int]: 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]: 0

Toggles whether an object ignores mouse clicks in a locked patcher.

jspainterfile[symbol]

JS Painter File

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.
