      "description": "From Derivative\n\t\t\n\t\t\n\t\t\n\t\t\n\t\tJump to navigation\n\t\tJump to search\n\t\t\nThe MIDI Out  sends MIDI events to any available MIDI devices when its input channels change. More flexibly, the Python midioutCHOP Class can be used to send any type of MIDI event to a MIDI device via an existing MIDI Out . In Tscript, the midi command can output MIDI events.\t\t\nThe MIDI devices can be other software programs (such as midisynth) or devices attached to the serial ports. Channels are used to control the sending of the MIDI events. The channels are evaluated over the last time slice (from the last Timeline position to the current).\t\t\t\nThe MIDI Out  sends MIDI events based on any changes to its input channels. The channels have to be named appropriately, like ch3c14 and ch7n60.\t\t\t\nAn event is sent every time a channel changes its value during this slice. All timing is preserved, as long as the Timeline is running in realtime (the \"Realtime\" flag is in the top menu bar). \t\t\t\nNaming the  channels: Channels are mapped to events by their name. Events like notes, controllers and velocities must be followed by the note/controller number (n65, c7). If the number is left off a note event, the note number is the value of the channel. Other events, which are sent to the entire channel, do not need a trailing number (pc, pw). The channel prefix can be used to identify the MIDI channel the event should be sent on (i.e. \"ch1n45\" assigns that TouchDesigner channel to note 45 messages on MIDI channel 1).  Channels can always be renamed with a Rename CHOP before entering the MIDI Out CHOP.\t\t\t\nThe MIDI Out  sends MIDI velocity as well. The values of the channels entering the MIDI Out CHOPs are sent as the velocity of the note. If Normalize is \"None\", the channel needs to be 0 to 127. If Normalize is \"0 to 1\", channel values between 0 and 1 are scaled to be MIDI 0 to 127.\t\t\t\nThe \" Every \" option cooks the  every frame, even if the  isn't being displayed. All Volume Off and All Volume On flags are new and emit events for Controller 7 of all 16 channels. MIDI output go in a separate thread to allow output that slows TouchDesigner less. It now works in  mode for note events and controller events. (Not for Program Change or Sysex messages yet) Note channels only trigger anew Note On when the input channel goes from 0 or less to a value greater than zero. Similar for Note Off events.The channel name determines how it is interpreted.\t\t\t\nFor example,\t\t\t\n\nch3n60 - this channel is interpreted as channel3 note 60. A Note On event is sent when the value goes from 0 or less to greater than zero\nch5n - This channel will contain note numbers.¬† The value quantized to an integer, and when the integer value changes, the note of the old value goes off and the note of the new value goes on. If the channel steps from 53 to 78, it sends a Note Off event for note 53, and a Note On event for note 78.\nch14c7 - the value of the channel is sent to controller 7 (volume) of channel 14. By default, the values 0 to 1 are mapped to MIDI value 0 to 127.These features work in  mode:\t\t\t\n\nBy default, channels are to start with \"ch\" followed by the channel number (1-16). In the case of notes, it is followed by \"n\" for notes, then digits for the note number. In the case of controllers, it is followed by \"c\" and a controller number. These prefixes can be altered. MIDI Out now interprets aftertouch, pressure, pitchwheel channels, and outputs these events to the MIDI stream. Note-normalization is added allowing 0 to 127 and 0 to 1 ranges. MIDI Out reads a bar ramp channel to output MIDI clock events¬† (with a channel popup menu to the parameter to select the channel name). Program change events are implemented through the \"pc\" channels.both 7 and 14 bit controller events can be output. You can capture a MIDI stream and output it to a file.See also the MIDI In DAT, MIDI Event DAT, MIDI In Map CHOP, MIDI In CHOP, midi command.\nmidioutCHOP_Class\n\nContents\n \n \n \n \n \n \n \n \n \n \n \n\n\n\n\n\n  active - Enable or disable the MIDI Out .\n\n\n\t\t\n  destination -  - Where the MIDI events are sent to.

An operator cooks when (1) its inputs change, (2) its Parameters change, (3) when the timeline moves forward in some cases, or (4) Scripting commands are run on the node. When the operator is a Panel Component, it also cooks when a user interacts with it. When an operator cooks, it usually causes operators connected to its output to re-cook. When TouchDesigner draws the screen, it re-cooks all the Dependencies - the necessary operators in all Networks, contributing to a frame's total \"cook time\".\n\n\n\nThe term \"Frame\" is a measurement of time used (1) in the Timeline, (2) as a time-unit in CHOPs, and (3) as a time unit in movie files that are read into TOPs and written out from TOPs. The frame rate is the frames per second (FPS).\n\n\n\nA 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 contain the CHOP channels' samples between the last and the current cook frame.\n\n\n\nThe location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.\n\n\n\nThe sub-Family of Component types that are used to define and render 3D scenes. A Geometry Component is an Object that contains the 3D shapes to render. A Camera COMP and Light COMP are other Object types. Separately, \"Objects\" also refers to Python objects.\n\n\n\nAn Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a python Script or GLSL Shader, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.\n\n\n\nA 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. TOPs have Channel Mask, a similar feature.\n\n\n\nsamples-per-second of a CHOP. Each CHOP in your network has a sample rate. In contrast, the overall timeline has a Frame Rate, which is the number of frames to cook and display per second, generally your monitor display frequency, default 60.\n\n\n\nExporting 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 CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.\n\n\n\nEvery 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.\n\n\n\nTouchDesigner is a hierarchy of components. \"root\" is the top-most network in the hierarchy. The Network Path or Path for root is simply /. A typical path is /project1/moviein1.\n\n\n\n\n\n\n\n\nRetrieved from \"https://docs.derivative.ca/index.php?title=MIDI_Out_CHOP&oldid=30517\"\n\t\tCategory: CHOPs",

      "description": "The MIDI Out  sends MIDI events to any available MIDI devices when its input channels change. More flexibly, the Python midioutCHOP Class can be used to send any type of MIDI event to a MIDI device via an existing MIDI Out . In Tscript, the midi command can output MIDI events.\t\t\nThe MIDI devices can be other software programs (such as midisynth) or devices attached to the serial ports. Channels are used to control the sending of the MIDI events. The channels are evaluated over the last time slice (from the last Timeline position to the current).\t\t\t\nThe MIDI Out  sends MIDI events based on any changes to its input channels. The channels have to be named appropriately, like ch3c14 and ch7n60.\t\t\t\nAn event is sent every time a channel changes its value during this slice. All timing is preserved, as long as the Timeline is running in realtime (the \"Realtime\" flag is in the top menu bar). \t\t\t\nNaming the  channels: Channels are mapped to events by their name. Events like notes, controllers and velocities must be followed by the note/controller number (n65, c7). If the number is left off a note event, the note number is the value of the channel. Other events, which are sent to the entire channel, do not need a trailing number (pc, pw). The channel prefix can be used to identify the MIDI channel the event should be sent on (i.e. \"ch1n45\" assigns that TouchDesigner channel to note 45 messages on MIDI channel 1).  Channels can always be renamed with a Rename CHOP before entering the MIDI Out CHOP.\t\t\t\nThe MIDI Out  sends MIDI velocity as well. The values of the channels entering the MIDI Out CHOPs are sent as the velocity of the note. If Normalize is \"None\", the channel needs to be 0 to 127. If Normalize is \"0 to 1\", channel values between 0 and 1 are scaled to be MIDI 0 to 127.\t\t\t\nThe \" Every \" option cooks the  every frame, even if the  isn't being displayed. All Volume Off and All Volume On flags are new and emit events for Controller 7 of all 16 channels. MIDI output go in a separate thread to allow output that slows TouchDesigner less. It now works in  mode for note events and controller events. (Not for Program Change or Sysex messages yet) Note channels only trigger anew Note On when the input channel goes from 0 or less to a value greater than zero. Similar for Note Off events.The channel name determines how it is interpreted.\t\t\t\nFor example,\t\t\t\n\nch3n60 - this channel is interpreted as channel3 note 60. A Note On event is sent when the value goes from 0 or less to greater than zero\nch5n - This channel will contain note numbers.¬† The value quantized to an integer, and when the integer value changes, the note of the old value goes off and the note of the new value goes on. If the channel steps from 53 to 78, it sends a Note Off event for note 53, and a Note On event for note 78.\nch14c7 - the value of the channel is sent to controller 7 (volume) of channel 14. By default, the values 0 to 1 are mapped to MIDI value 0 to 127.These features work in  mode:\t\t\t\n\nBy default, channels are to start with \"ch\" followed by the channel number (1-16). In the case of notes, it is followed by \"n\" for notes, then digits for the note number. In the case of controllers, it is followed by \"c\" and a controller number. These prefixes can be altered. MIDI Out now interprets aftertouch, pressure, pitchwheel channels, and outputs these events to the MIDI stream. Note-normalization is added allowing 0 to 127 and 0 to 1 ranges. MIDI Out reads a bar ramp channel to output MIDI clock events¬† (with a channel popup menu to the parameter to select the channel name). Program change events are implemented through the \"pc\" channels.both 7 and 14 bit controller events can be output. You can capture a MIDI stream and output it to a file.See also the MIDI In DAT, MIDI Event DAT, MIDI In Map CHOP, MIDI In CHOP, midi command.\nmidioutCHOP_Class\n\nContents\n \n \n \n \n \n \n \n \n \n \n \n\n\n\n\n\n  active - Enable or disable the MIDI Out .\n\n\n\t\t\n  destination -  - Where the MIDI events are sent to.
