MIDI In Map CHOP

Summary
[edit]

See first the MIDI In DAT. The MIDI In Map CHOP reads in specified channels from the MIDI Device Mapper Dialog which prepares slider channels starting from s1, s2, etc. and button channels starting with b1, b2 and so on. The MIDI In Map CHOP selects from these channels.

NOTE: (Apr 12 09) This page needs to be updated with the info in the release notes.

Another CHOP, the MIDI In CHOP retrieves MIDI data more directly but it is less portable as it addresses the MIDI channel numbers, note numbers and controller numbers in the CHOP, so in order to change the MIDI mapping, you need to change the settings in TouchDesigner, whereas with the MIDI In Map CHOP, users need only set the mapping in the Dialogs -> MIDI Device Mapper.

See also the MIDI In DAT, MIDI Event DAT, MIDI In CHOP, MIDI Out CHOP, midi command, MIDI Device Mapper Dialog.

Parameters - MidiInMap Page

Device Table device - Path to the MIDI device Table DAT.

Device ID id - Specify the id of which device to use.

Sliders sliders - The slider controllers to import from the MIDI Mapper. For example to import the first 16 sliders, slider 20 and sliders 32 to 40, type:

 s[1-16] s20 s[32-40]		

Buttons buttons - The buttons to import from the MIDI Mapper. For example to import the first 16 buttons, button 20 and buttons 32 to 40, type:

 b[1-16] b20 b[32-40]		

Include Velocity in Buttons bvelocity -

Parameters - Common Page

Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.

Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.

Sample Rate Match srselect - - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.

  • Resample At First Input's Rate first - Use rate of first input to resample others.
  • Resample At Maximum Rate max - Resample to the highest sample rate.
  • Resample At Minimum Rate min - Resample to the lowest sample rate.
  • Error If Rates Differ err - Doesn't accept conflicting sample rates.

Export Method exportmethod - - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.

  • DAT Table by Index datindex - Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
  • DAT Table by Name datname - Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
  • Channel Name is Path:Parameter autoname - The channel is the full destination of where to export to, such has geo1/transform1:tx.

Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.

Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).

An which operate on (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.

The location of an operator within the TouchDesigner environment, for example, /geo1/torus1, a node called torus1 in a component called geo1. The path / is called . To refer instead to a filesystem folder, directory, disk file or http: address, see .

samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.

A Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.

A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator.

Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See .

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

Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a by pressing the keyboard shortcut 'p'.

TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The is simply /. A typical path is /project1/moviein1.
