table~ Reference

Signal Table Lookup

table~

Description

Use table~ to remap incoming signal values with a table object.

Arguments

None.

Attributes

embed [int] (default: 1)

When the embed attribute is enabled, table values are saved in a patcher file and restored when it is reopened.

extend [int]

The extend attribute controls how table~ responds when an input index value (either signal or float) is less than zero or greater than the table size.

Possible values:

0 = 'Zero' ( Output zero )
When extend is Zero (0), a zero signal is output when the index is outside the table bounds.

1 = 'Extend' ( Output lowest or highest table values )
When extend is set to Extend (1), table~ outputs the value at index 0 is output when the input index less than zero. It outputs the value at the highest table index is when the input index is greater than the table size.

2 = 'Wrap' ( Wrap index )
When extend is set to Wrap (2), table~ performs a modulo operation on the input index. Example: if the table size is 128 and the input is 130, the value at index 2 (130 mod 128) will be output.

3 = 'Ignore' ( Don't change output )
When extend is set to Ignore (3), any input index outside the table size is ignored and does not change the output.

inmap [atom]

The inmap attribute specifies a range of input samples to map to table indices. For instance if your input signal will be between 0 and 1, you can use an inmap of 0 1, which will scale to the current size of the table. If the table changes size, the current input map adjusts automatically. To clear the current inmap, use a value of none or 0 0.

inputmode [int]

Input Mode

Possible values:

0 = 'Lookup'
1 = 'Increment Index'
2 = 'Random Distribution'

interp [int]

The interp attribute determines how input values between integer table indices produce output.

Possible values:

0 = 'None' ( Truncate Index )
When interp is set to None (0), an incoming value is truncated to its integer value before the lookup. No interpolation is performed.

1 = 'Linear' ( Linear Interpolation )
When interp is set to Linear (1), the output for any input value between two table indices is linearly interpolated between the table values at those two indices. For example, an input of 1.5 -- with table values of 5 at index 1 and 10 at index 2 -- produces an output of 7.5.

2 = 'Round' ( Round Index )
When interp is set to Round (2), an incoming value is rounded to the nearest integer value before the lookup. No interpolation is performed.

name [symbol]

The name attribute permits table data to be shared among multiple table objects (table~, table, or itable) with the same name. Changing the name switches the table used for lookup.

outscale [atom]

The outscale attribute specifies a range of output samples. The current range of the table will map to the specified range. For example, if you want the output of table~ to range from 0 - 1, set outscale to 0 1. The output scaling adjusts automatically to keep output values in the specified range even if the table range changes. To clear the current outscale use a value of none or 0 0.

parameter_enable [int]

Enables use of this object with Max for Live Parameters.

parameter_mappable [int] (default: 1)

When parameter_mappable is enabled, the object will be available for mapping to keyboard or MIDI input using the Mappings feature. (default = 1).

range [int]

Sets the range of table values. If the signed attribute is not enabled, the maximum table value is one less than the range. For example if the range is 128, table values range from 0 to 127. If signed is enabled, table values range from +/- the range value. For example if the range is 128, table values will be -128 to 128.

signed [int] (default: 0)

If the signed attribute is enabled, table values range from +/- the range value. For example if the range is 128, table values will be -128 to 128. Changing the state of signed attribute does not modify table values.

size [int]

Sets the number of elements in the table. Indices range from 0 to one less than the size.

triggermode [int]

Trigger Mode

Possible values:

0 = 'Zero to Non-Zero'
1 = 'Change'

Parameter Attributes

Order

Typeint

Sets the order of recall of this parameter. Lower numbers are recalled first. The order of recall of parameters with the same order number is undefined.

Parameter Mode Enable

Typeint

Parameter Mode Enable (not available from Parameters window)

Link to Scripting Name

Typeint

When checked, the Scripting Name is linked to the Long Name attribute.

Long Name

Typesymbol

The long name of the parameter. This name must be unique per patcher hierarchy.

Short Name

Typesymbol

Sets the short name for the object's visual display. The maximum length varies according to letter width, but is generally in a range of 5 to 7 characters.

Type

Typeint

Specifies the data type. The data types used in Max for Live are:

Float
Int
Enum (enumerated list)
Blob

Note: By convention, the Live application uses floating point numbers for its calculations; the native integer representation is limited to 256 values, with a default range of 0-255 (similar to the char data type used in Jitter). When working with Live UI objects whose integer values will exceed this range, the Type attribute should be set to Float, and the Unit Style attribute should be set to Int.

Range/Enum

Typelist

When used with an integer or floating point data type, this field is used to specify the minimum and maximum values of the parameter.
When used with an enumerated list (Enum) data type, this field contains a space-delimited list of the enumerated values (if list items contain a space or special characters, the name should be enclosed in double quotes).

Modulation Mode

Typeint

Sets the Modulation Mode used by the Live application. The modulation modes are:

None
Unipolar
Bipolar
Additive
Absolute

Modulation Range

Typelist

This parameter is only used with the Absolute modulation mode. It specifies defines the range of values used.

Initial Enable

Typeint

When checked (set to 1), the UI object can store an initialization value. The value is set using the Initial attribute (see below).

Initial

Typelist

Sets the initial value to be stored and used when the Initial Enable attribute is checked.

Unit Style

Typeint

Sets the unit style to be used when displaying values. The unit style values are: Int: displays integer values
Float: displays floating point values
Time: displays time values in milliseconds (ms)
Hertz: displays frequency values (Hz/kHz).
deciBel: displays loudness (dB)
%: Percentage
Pan: displays Left and Right values
Semitones: displays steps (st)
MIDI: displays pitch corresponding to the MIDI note number
Custom: displays custom data type
Native: defaults to floating point values

Custom Units

Typesymbol

Sets the units to be used with the 'Custom' unit style (see "Unit Style", above). Custom unit strings may be simple symbols (e.g. "Harmonic(s)"), in which case the parameter's value will be displayed in its 'Native' display mode, followed by the symbol (e.g. "12 Harmonic(s)" for an Int-typed parameter or "12.54 Harmonic(s)" for a Float-typed parameter). For additional control over the numerical component displayed, a sprintf-style string may be used (e.g. "%0.2f Bogon(s)", which would display a value such as ".87 Bogons").

Exponent

Typefloat

When set to a value other than 1., the parameter's input and output values will be exponentially scaled according to the factor entered in this column.

Steps

Typeint

The number of steps available between the minimum and maximum values of a parameter. For instance, if the parameter has a range from 0.-64., with Steps set to 4, the user can only set the parameter to 0, 21.33, 42.66 and 64.

Parameter Visibility

Typeint

For automatable parameters (Int, Float, Enum), 'Stored Only' disables automation, although parameter values are stored in presets. 'Hidden' causes the parameter's value to be ignored when storing and recalling data. Non-automatable parameters (Blob) are 'Stored Only' by default, and can be set to 'Hidden', if desired.

Update Limit (ms)

Typeint

Speed limits values triggered by automation.

Defer Automation Output

Typeint

Defers values triggered by automation.

Messages

bang

The bang message treats the table as a probability distribution and outputs a signal corresponding to a randomly chosen index within the table. A location in the table with a higher value is more likely to have its index selected.

int

See description for float

float

When a signal is not connected to the inlet of table~, a number sets the index to use for table lookup output. If the number contains a fractional part and interp is set to Linear, the output will be interpolated between two table values. The number is also mapped to an index according to the current setting of the inmap attribute and the table value is scaled according to the outscale attribute.

(mouse)

Double-clicking on a table~ object opens a window where you can edit the values of the lookup table.

goto

The word goto, followed by a table index, sets the next table index used by either the prev or next messages as they increment or decrement through the table. Unlike a float or int, goto itself does not change the output of the table~ object and its index is not modified by the inmap attribute.

next

When a signal is not connected to the inlet of table~, the next message adds one to the most recent table index set by the int, or float, then causes the table~ to output the value at this index as a signal. If a goto message immediately preceded next, the value at the specified index is output. Note that next does not force the table index to an integer value, so it preserves any fractional part of the index caused by a previous float message. When next increments the index and it is larger than the table size, it wraps around to zero.

prev

When a signal is not connected to the inlet of table~, the prev message subtracts one from the most recent table index set by the int, or float, then causes the table~ to output the value at this index as a signal. If a goto message immediately preceded prev, the value at the specified index is output. Note that prev does not force the table index to an integer value, so it preserves any fractional part of the index caused by a previous float message. When prev decrements the index and it becomes less than zero, it will wrap around to the end of the table.

signal

Incoming signal values are used as indices for table lookup.
