 +  * **select**: reference a TOP from any other location: 
 +   * drag the TOP you wish to reference into the ''TOP'' parameter in the parameter window of ''switch'' 
 +   * it's sort of like a "send" and "receive" for Pd and that's all it does? 
 + * **threshold**: highlight areas (white vs alpha) that are beyond a certain brightness

 === CHOPS === === CHOPS ===
 +//CHOPS can be **single sample** or **multi sample**//
   * ''Select'': filter for a specific output. Example: look for DONE channel name coming out of ''timer'' chop.   * ''Select'': filter for a specific output. Example: look for DONE channel name coming out of ''timer'' chop.

 +    * drag ''moviefilein'' TOP onto this CHOP to get the audio of a specific movie
 +    * to actually get a movie with audio then connect ''moviefilein'' TOP to ''moviefileout'' TOP then drag ''Audio Movie'' CHOP onto ''moviefileout'' TOP
 +  * ''LFO'': send sine, cosine, square, pulse, etc.
 +  * ''Trigger'': sort of like a fully adjustable ADSR
 +    * turn ''time slice'' in the parameter window **off** to see the envelope
 +  * ''Count'': increment
 +  * ''Filter'': smooth the data
 +  * ''Lag'': much like filter but has an accell/decel feature
 +  * ''Fan'': split from a single channel to multiple channels
 +  * ''Math'': can combine CHOPS or combine channels. Also tweak the range of output values/
 +  * ''Merge'': merge multiple CHOPS into 1 CHOP with different channels. Use for example when doing the same math operation on multiple CHOPS
 +  * ''Switch'': switch between multiple sources
 +  * ''Replace'': replace input 1 with input 2 if input 2 has data
 +  * ''Fan'': take a serious of channels and fan in to 1 channel
 +  * ''Timer'':
 +  * ''Event'': similar to ''trigger'' but can handle multiple triggered values at different times
 +  * ''Trail'': record values over time. Set ''Grow Length'' on to increase time window indefinitely.
 +    * can change it to capture only when input data is cooked
 +  * ''Analyze'': Average, Sum, RMS, Peaks, etc.
 +  * ''Logic'': turn on or off depending on the values coming in. For example, turn on when input > 9
 +
 +=== multi sample ===
 +  * ''Pattern'': Sine, Cosine, etc.
 +    * can accept another input multisample which can be combined with the pattern (see ''Combine Channels'' in the ''Channel'' tab of the parameter window) 
 +    * note the "extend region left" and "extend region right"
 +  * ''Trim'': cut or extend the multisample
 +  * ''Audioosc'': you can set the sample rate to match the sample size of a pattern CHOP or similar CHOP
 +  * ''Constant'': make it multisample in the ''Channel'' tab
 +  * ''Shuffle'': sequence or split multisample or single sample CHOPS together
 +    * example: split a multisample CHOP with 10 points into a single sample CHOP with 10 channels by choosing ''split all samples''as the method in the parameter window

 +  - alternatively, with the CHOP viewer window active, drag the CHOP op directly onto the TOP op and choose the parameter to map to in the pop menu.
 +    - With this alternative method the reference is not Python code and therefore may not be as adaptable in some situations?
 +    - This appears to be the same as following the original method but choosing ''Export Chop'' except when choosing ''Export Chop'' you also seem to get a bonus export table that gets created (maybe?)

 ==== Tips and Tricks ==== ==== Tips and Tricks ====

 +  * Collapsing a network: select all ops in the network, R-click and choose "collapse selected"
 +  * ''File''->''Export Movie'' to save a video. Suggestion: turn ''realtime'' off to avoid glitches
 +  * default files are in ''Program Files''->''Derivative''->''TouchDesignerVERSION''->''Samples''->''Map''
 +  * when needing constantly changing values take a look in the ''Channel'' tab of the parameter window at ''Time Slice''

 +==== Composting Operations ====
 +  * **Screen**: add two images together without producing values above white
 +
 +==== Sending and Receiving Video ====
 +  * NDI: video over IP. Can be used for local video sharing
 +    * ''NDI'' DAT shows in a table all courses and streams available
 +    * ''NDI out'' TOP sends an NDI stream
 +    * ''NDI in'' TOP receives NDI stream. Fill in the source name parameter
 +  * Syphon (MacOS)/Spout (Windows): in and out TOPS share textures and images via shared memory on the same machine
 +  * Video Stream Out: stream content over local network or internet. Send to YouTube or Twitch for example. Might be an easy way to send to VLC as well?
 +
 +==== Built-in Variables ====
 +  * ''me.time.frame'': frame # sent by timeline at a given moment
 +
 +==== Units ====
 +  * ''i'': index or sample
 +
 +==== Pattern Matching ====
