Sequential Parameters

Sequential parameters are used to create copies of a parameter or group of parameters that a user can repeat indefinitely. They are numerically ordered starting at 0 or 1. For example, the Constant CHOP to create multiple channels, or the GLSL TOP to create multiple vectors, arrays, and matrices.

You can add and remove sequential parameters to/from the end of the list using the +/- buttons at the bottom of a parameter "block". You can also right-click on a sequential parameter and use 'Insert Parameter' to splice in an extra parameter. Note that inserting shifts the parameters below down one position which has the effect of changing all the parameter names (tokens) for every parameter below the insertion point. It should be used with caution if you are exporting, referencing, or binding any of the channels.

You can manage sequential parameters with python using the Sequence Class.

An Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.

An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

Every operator in TouchDesigner has a set of control Parameters that can be integer or floating point numbers, menus, binary toggles, text strings or operator paths, which determine the output of the operator.
