Summary
[edit]

The MIDI Event DAT logs all MIDI messages coming into TouchDesigner from all MIDI devices. It also includes MIDI messages originating from TouchDesigner. It outputs columns in a table format: message, type, channel, index, value.

The table is FIFO "first-in first-out" and limited to parameter-set number of lines. An optional script may be run for each packet received.

See also the MIDI In DAT, MIDI In Map CHOP, MIDI In CHOP, MIDI Out CHOP, Tscript midi() Command.

Parameters - Connect Page

Active active - Logs MIDI events when turned on.


Parameters - Filter Page

Skip Sense skipsense - Does not log sense messages when this is turned on.

Skip Timing skiptiming - Does not report timing messages when this is turned on.

Filter Messages filter - Turning this on enables the message filtering parameters below.

Message message - Filter by the MIDI message content. Example "Control Change"

Channel channel - Filter by the MIDI message channel. Channels range from 1 to 16.

Index index - Filter by the MIDI message index. Indices range from 1 to 128.

Value value - Filter by the MIDI message value. Values range from 0 to 127.

Dir dir - Filter by the message direction, "input" or "output".


Parameters - Received Messages Page

Callbacks DAT callbacks - Runs this script once for each row added to the table (ie. MIDI event recieved). See midieventDAT_Class for usage.

Execute from executeloc - - Determines the location the script is run from.

  • Current Node current - The script is executed from the current node location.
  • Callbacks DAT callbacks - The script is executed from the location of the DAT specified in the Callbacks DAT parameter.
  • Specified Operator op - The script is executed from the operator specified in the From Operator parameter below.

From Operator fromop - The operator whose state change will trigger the DAT to execute its script when Execute is set to Specified Operator. This operator is also the path that the script will be executed from if the Execute From parameter is set to Specified Operator.

Clamp Output clamp - The DAT is limited to 100 messages by default but with Clamp Output, this can be set to anything including unlimited.

Maximum Lines maxlines - Limits the number of messages, older messages are removed from the list first.

Clear Output clear - Deletes all lines except the heading. To clear with a python script op("opname").par.clear.pulse()

Bytes Column bytes - Outputs the raw bytes of the message in a separate column.


Parameters - Common Page

Language language - - Select how the DAT decides which script language to operate on.

  • Input input - The DAT uses the inputs script language.
  • Node node - The DAT uses it's own script language.


Edit/View Extension extension - - Select the file extension this DAT should expose to external editors.

  • dat dat - various common file extensions.
  • From Language language - pick extension from DATs script language.
  • Custom Extension custom - Specify a custom extension.


Custom Extension customext - Specifiy the custom extension.


Word Wrap wordwrap - - Enable Word Wrap for Node Display.

  • Input input - The DAT uses the inputs setting.
  • On on - Turn on Word Wrap.
  • Off off - Turn off Word Wrap.

An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.

TouchDesigner's original built-in Command scripting language prior to Python.

Operators that have 1 or more input, like a Math CHOP, are called filters. See Generator.

A CHOP outputs one or more channels, where a channel is simply a sequence of numbers, representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. See also Export.

The generic thing that holds an Operator, and includes Flags (display, bypass, lock, render, immune) and its position/size in the network. Whether you "lay down an Operator" or "lay down an Node", you're doing the same thing.

Any of the procedural data operators. OPs do all the work in TouchDesigner. They "cook" and output data to other OPs, which ultimately result in new images, data and audio being generated. See Node.
