IWS Icon Wotja Script 20

Powerful Music Engine Scripting

Note: "Generators" is the name used in Wotja 20, for what was referred to as "Voices" in older versions.

Wotja contains a powerful scripting engine which, while entirely optional to use, offers tremendous power.

The Wotja Script Editor is accessed from Wotja as follows:

The Wotja Script Sandbox is accessed from Wotja as follows:

Wotja Scripting is aimed at generative music fans who want to "hack" Wotja, coders and hackers who want to play with music, and anybody who uses Wotja and wants to push the outer limits of what Wotja can do out of the box.

New in the IWS 20:

  • Improvement: "Generators" is the name used in Wotja 20, for what was referred to as "Voices" in older versions.
  • Improvement: Some things in the IWS have been renamed:
    • In Scripts you should now use the "Generator" object type name rather than the previous "Voice" nomenclature (though "Voice" is still supported)
    • The following changes are auto-applied to any old scripts:
      • Replace "Voice" with "Generator" in scripts
      • Replace "Piece" with "Cell" in scripts
    • Renamed imeVoiceEnvelopePercentGet > imeGeneratorEnvelopePercentGet
    • Renamed imeVoiceEnvelopePercentSet > imeGeneratorEnvelopePercentSet
    • Renamed imeVoiceMIDIChannelGet > imeGeneratorMIDIChannelGet
    • Renamed imePieceElapsedPercentGet > imeMixElapsedPercentGet
    • Renamed onImeVoiceComposed > onImeGeneratorComposed
    • Renamed onImeVoiceUserController > onImeGeneratorUserController
  • Improvement: Other IWS related changes:
    • Renamed "Voice" button to "Generator" - shown when panel not embedded
    • Renamed "Generative Piece Rules" button to "Generative Cell Rules"
    • Renamed "Piece Script" to "Cell Script" in Cell Parameters
    • Renamed "Voice Script" screen to "Generator Script"
    • Renamed "Piece Script" screen to "Cell Script"
  • Improvement: Added Cell Cookbook/Change Root Randomly At Start.wotjascript
  • Fixed: Script references to the "Next Note Rule" object type name now work correctly

The Wotja Script language is based on the widely used ECMAScript scripting langauge (ECMAScript E5/E5.1). ECMAScript (also referred to commonly by the name JavaScript), is very powerful, fast and easy to learn. ECMAScript is a very popular embedded scripting langage, and is widely used in the web, gaming and multimedia worlds. Wotja adds various Wotja-specific functions to the language. These extensions are outlined later in this document; we call them "Event Handler Script Functions" or "Triggers". We give you lots of examples to get you started.

Wotja Scripts and Wotja Scripting (hereafter just "scripts", scripting etc.) can be used in two separate contexts:

  • Event Handler Script Functions ("Triggers")

    The most common way to use scripting in Wotja is to use the Script Editor Window accessed from the IME Generator Scripts and Cell Scripts cells. This allows you to create Event Handler Script Functions ("Triggers"), which are small bits of code in the widely used ECMAScript language. The specially named Event Handler Script Functions in these scripts are triggered when various events happen when a mix is playing. Using Event Handler Script Functions allows you to tell the Generator or Mix Objects to behave in very powerful ways while the mix is playing.

  • Sandbox Scripts

    You can use the Wotja Sandbox script window to experiment with Script code. You can show the Wotja Sandbox from the main Mix screen (press the Action menu button, and select the Script Sandbox item).

Why would you want to use Scripting?

Are you a generative music fan who wants to see what your own custom code can achieve when leveraging a hugely powerful app such as Wotja? Are you code hacker who want to play with music? Are you a Wotja expert who wants to push the outer limits of what Wotja can do out of the box?

With careful use of Wotja's Event Handler Script Functions, you can do a lot of cool things, while turning Wotja into a custom hyperinstrument.

You can, if you wish, create Event Handler Script Functions to run in response to the following events:

  • start of playback
  • every bar
  • when a note is composed by the IME
  • end of playback
  • in response to external MIDI CC via e.g. keyboard controller
  • in response to external MIDI Note on/off via e.g. keyboard controller

Every script can manipulate a large number of things in Wotja in real-time. Some examples: manipulating music rules, playing with mutation, altering patterns; and what have you.

By creating code to respond to external MIDI events, you can in turn manipulate various properties of Wotja, such as auto-chording parameters, rule settings etc.

User Interface Updates

If you change a property with a script function such as imeParameterSet, the user interface doesn't always update to reflect your call; you'd need to refresh the table that displays your updated parameter, to see the change in the user interface. We hope to be able to improve this behaviour at some future point.

If you change a parameter with the user interface, and that parameter is later changed by a script; the latter script call will override your user interface change. Don't get confused by this!

If you have a script which copies a parameter value at start, and then resets it when the mix stops; where you've in between changed the parameter through the user interface; the latter script call will override your user interface change. Don't get confused by this!

Latency and Timing

The IME composes events a little bit in advance of when you'll hear them. This is to ensure that the notes are composed, in time for them to be picked-up by the ISE; the system also does the audio processing required by the ISE a little ahead of time before you actually hear it. Added together, this means that script code run in response to, say, onImeBar won't always appear precisely synchronized to what you're listening to!

Infinite Loops

Please be careful not to implement so-called Infinite Loops in your script code, as that might cause the Wotja application to crash.

Recursion (recursive function calls)

Please be careful not to write script code that results in a lot of Recursion, as that might cause the Wotja application to crash.

Scripting Interface

Wotja Script Editor

Click image for large

The Wotja Script Editor Window

When you decide to edit a Cell Script or Generator Script parameter, or if you select the Script Sandbox menu item, you are presented with the Script Editor window. It supports syntax-colored code editing and a console window at the bottom lets you capture logs from your scripts.

  • Cell/Generator Script Editor

    In this mode, the top panel allows you to edit Wotja Script Functions associated with your Cell or Generator..

  • Script Sandbox

    In this mode, it is used to create and run scripts that aren't saved, and that don't access Mix properties. It is there for you to experiment with Wotja Script!

The top panel allows you to edit Wotja Script Functions associated with your object.

The panel can contain as many functions as you want, or as few as you want. Leave it blank if you don't want to use any scripting.

Here is an example with just one trigger script function:


// Just one function!

function onImeBar(bar) {
  wjsLog ("onImeBar: Bar number=" + bar)
}

Here is an example with three trigger script functions:


// Three functions!

function onImeStart() {
  wjsLog ("onImeStart!")
}

function onImeBar(bar) {
  wjsLog ("onImeBar: Bar number=" + bar)
}

function onImeStop() {
  wjsLog ("onImeStop!")
}

Test & Apply (only for Generator or Cell Script)

Pressing this button will compile any Wotja Script that you type in the large text area at the top of the window, and if the script looks valid, it will send the script to be stored within the Mix. It will take effect immediately (if your Mix is running).

Run Script (only for Script Sandbox)

Pressing this button will compile any Wotja Script that you type in the large text area at the top of the window, and display any results in the bottom panel. Use Run Script to quickly check your script for obvious syntax errors.

Note that any changes you make here aren't saved within the mix.

Open

Pressing the Open button displays the Wotja Scripts Window, where you can select a Wotja Script file from either built-in examples, or from ones you've saved yourself (which have a .wotjascript extension). Your saved custom scripts are listed in the top section; you can save your own custom scripts in this section, by using the Save button.

Save

Pressing the Save button lets you save the contents of your Script editor window to a document with the .wotjascript extension. You can then easily find and re-open that Script using the Open button (your saved custom scripts are listed in the top section).

Help

Pressing the Help button displays help on Wotja Scripting system!

Back (<)

Pressing the Back (<) button will close the screen. If you're editing a Generator or Cell script, you'll first be prompted to save or discard any changes you might have made.

Cancel

Pressing the Cancel button will discard your changes.

Test Results

Any test results are displayed in the Test Results area at the bottom.

Clear

Pressing the Clear button in the bottom area, quickly erases the text in the bottom panel.

Event Handler Script Functions ("Triggers")

Triggers can be assigned to most Objects, including the Cell and Generator Objects.

You can enter these scripts using the following parameter groups / views:

Logging output to the Script console with wjsLog

The wjsLog function may be used to write text to the Script Console; this is very useful for debugging your scripts!

Wotja Scripts Window

The Wotja Scripts window lets you select from a number of built-in scripts that are provided by Intermorphic. There are simple implementations of each of the Event Triggers functions for both Generator and Cell scripts, and there are a large number of Cookbook scripts for both Generator and Mix. The Cookbook scripts which are often quite detailed, and which are designed to help you get started with writing your own scripts.

When in this Window, select the item you wish to use in the Script Editor.

The top section lists any Scripts that you might have saved yourself; you can press the "Trash Can" icon to delete your user script.

Generator - Scripts

The Generator Scripts parameter allows you to embed small Event Handler Script Functions, which are small bits of code in the widely used JavaScript language, that are triggered when various events happen when the Generator is playing. Specially named Event Handler Script Functions in these scripts are triggered when various events happen when a mix is playing.

Start

The onImeStart Event Handler Script Function is called once at the start of the Generator's owning cell, when that cell starts playing.

The function has no parameters.


function onImeStart() {
  wjsLog ("Generator start!")
}

Bar

The onImeBar Event Handler Script Function is called at the start of every bar while the mix is playing in its cell, starting from 1.

The function has one parameter:

  • bar   the bar number, starting from 1.

function onImeBar(bar) {
  wjsLog ("Generator Bar number=" + bar)
}
  

Stop

The onImeStop Event Handler Script Function is called once at the end of the Generator's owning cell, just as that Cell stops playing.

The function has no parameters.


function onImeStop() {
  wjsLog ("Mix stop!")
}
  

Composed

The onImeGeneratorComposed Event Handler Script Function is called when the Generator composes a note. Use this to emit MIDI CC events and what have you.

The function has five parameters:

  • generatorIndex   the generator index, starting from 0.
  • noteon   a value indicating if this is a note on event - true means note on, false means note off.
  • channel   the MIDI Channel, from 0 to 15 (MIDI channel is actually displayed in the IME Network screen as 1 to 16)
  • pitch   the MIDI pitch of the composed note, from 0 to 127.
  • velocity   the MIDI velocity of the composed note, from 1 to 127.

function onImeGeneratorComposed(generatorIndex, noteon, channel, pitch, velocity) {
  wjsLog ("Generator Composed index=" + generatorIndex + ", noteon=" + noteon + ", channel=" + channel + ", pitch=" + pitch + ", velocity" + velocity)
}
  

User Controller Changed

The onImeGeneratorUserController Event Handler Script Function is called when either of the Generator's User Controllers output value changes.

The function has three parameters:

  • generatorIndex   the generator index, starting from 0.
  • controllerIndex   the zero-based index of the controller; 0 means User Controller 1, 1 means User Controller 2.
  • value   the controller's new value, from 0 to 127.

function onImeGeneratorUserController(generatorIndex, controllerIndex, value) {
  wjsLog ("onImeGeneratorUserController, generatorIndex=" + generatorIndex + ", controllerIndex=" + controllerIndex + ", value=", + value)
}

  • cc   the CC event identifier, from 0 to 127.
  • value   the value of the CC event, from 0 to 127.

Note that your script will only respond to MIDI In CC Events that target the MIDI Channel that your generator is attached to.


function onMIDIInCC(channel, cc, value) {
  wjsLog ("Generator onMIDIInCC channel=" + channel + ", " +  cc + ", " +  value)
}
  

MIDI In Note

The onMIDIInNote Event Handler Script Event Handler Script Function is called whenever a MIDI Note On or Off event is received by the MIDI Input device.

The function has four parameters:

  • channel   the MIDI Channel, from 0 to 15 (MIDI channel is actually displayed in the IME Network screen as 1 to 16)
  • noteon   a value indicating if this is a note on event - true means note on, false means note off.
  • pitch   the MIDI pitch of the note event, from 0 to 127.
  • velocity   the velocity of the note event, from 0 to 127.

Note that your script will only respond to MIDI In Note Events that target the MIDI Channel that your generator is attached to.


function onMIDIInNote(channel, noteon, pitch, velocity) {
  wjsLog ("Generator onMIDIInNote channel=" + channel + ", noteon=" + noteon + ", " +  pitch + ", " +  velocity)
}

Script Function Reference


Wotja Script Utility functions

Wotja Script Utility functions all start with the wjs prefix


wjsLog ()

The function wjsLog may be used to display text in the Script Console; this is very useful for debugging your scripts!

Example:


function onImeStart() {
  wjsLog("Hello World!")
}

wjsGetRandom ()

This function returns a random integer.

The function has no parameters.

Example:

var value = wjsGetRandom ()

wjsRandomGetFromTo (minimum, maximum)

This function returns a random integer in the range of the two supplied values.

The function has two parameters:

  • minimum   the minimum value that can be returned
  • maximum   the maximum value that can be returned

Example:


function onImeStart() {
  // Get a random integer between 0 and 50 inclusive.
  var value = wjsRandomGetFromTo (0, 50)
  wjsLog("random value=", value)
}
          

IME related functions

The IME contains many powerful scripting features. The IME related functions all start with the ime prefix.


imeParameterSet (parameterName, newValue)

This function is used to set the object's parameter to the supplied value, for the object within whose trigger script you place this call.

The function has two parameters:

  • parameterName   the name of the parameter for which you want to set the value.
  • newValue   the new value to use.

Example:


function onImeStart() {
  // Set the Chord Depth to 4 (assuming we make this call from within a
  // Generator's trigger script!)
  var chordDepth = 4
  imeParameterSet("Chord Depth", chordDepth)
}
          

imeParameterGet (parameterName)

This function returns the value of the named parameter, for the object within whose trigger script you place this call. Note that the value returned is always a string, which you can convert to a number using tonumber().

The function has one parameter:

  • parameterName   the name of the parameter for which you want to determine the current value.

Example:


function onImeStart() {
  // Get the current Chord Depth (assuming we make this call from within a
  // Generator's trigger script!)
  var chordDepth = imeParameterGet("Chord Depth")
  wjsLog ("Chord Depth=" + chordDepth)
}
          

imeGeneratorMIDIChannelGet()

This function returns the MIDI channel (assuming the script is called from within a generator script!). The value returned is a value from 0 to 15 (MIDI channel is actually displayed in the IME Network screen as 1 to 16).

The function has no parameters.

Example:


function onImeStart() {
  var channel = imeGeneratorMIDIChannelGet ()
  wjsLog ("Channel=" + channel)
}
          

imeRuleElementGet (ruleObjectType, ruleObjectIndex, ruleElementIndex)

This function returns the rule element value of the specified index, for the indexed rule object. The value returned is a value between 0 and 127.

The function has the following parameters:

  • ruleObjectType   the object type i.e. one of "Scale Rule", "Harmony Rule", "Rhythm Rule", "Next Note Rule".
  • ruleObjectIndex   the index of the rule object of interest, starting at 0 for the first object.
  • ruleElementIndex   the index of the element; starting at 0 for the initial element.

Example 1:


function onImeStart() {
  // Dump out the scale rule element values, for the first scale.
  var scaleRuleIndex = 0
  var itemIndex = 0
  while (itemIndex < 12)
  {
    var value = imeRuleElementGet ("Scale Rule", scaleRuleIndex, itemIndex)
    wjsLog ("value=" + value)
    index = itemIndex + 1
  }
}
          

Example 2:


function onImeStart() {
  var scaleRuleCount = imeObjectCountGet("Scale Rule")
  wjsLog ("Scale Rule objects=" + scaleRuleCount)
  
  for (var scaleRuleIndex = 0; scaleRuleIndex < scaleRuleCount; scaleRuleIndex++) {
    // Dump out the scale rule element values, for the scale!
    var ruleName = imeObjectNameGet("Scale Rule", scaleRuleIndex)
    wjsLog ("Scale=" + ruleName)
    
    var itemIndex = 0
    while (itemIndex < 12)
    {
      var value = imeRuleElementGet ("Scale Rule", scaleRuleIndex, itemIndex)
      wjsLog ("itemIndex" + ", " +  itemIndex + ", " +  "value" + ", " +  value)
      itemIndex = itemIndex + 1
    }
  }
}
          

imeMIDISendCC (channel, cc, value [, delay])

This function emits the specified MIDI CC event.

The function has the following parameters:

Scripting Cookbook

Trigger Script Cookbook

A great way to start thinking about Event Handler Script Functions, is to look at various real examples of how to do various interesting things with Event Handler Script Functions!

Example: How to choose a random Mix Root every time the mix starts


// Choose a random root

function chooseRandomRoot() {
  var roots = ["A", "A#", "B", "C", "C#", "D", "D#", "E", "F", "F#", "G", "G#"]

  var rootIndex = wjsRandomGetFromTo(0, roots.length-1)
  var newRoot = roots[rootIndex]
  return newRoot
}

function onImeStart() {
  wjsLog ("onImeStart!")

  var newRoot = chooseRandomRoot()
  imeParameterSet("Mix Root", newRoot)
  wjsLog ("Mix Root now=" + newRoot)
}
 

Example: Change the scale to use depending on time of day

This is a script that you could use as a cell-level Bar trigger script.


function onImeStart() {
  var date = new Date()
  var hour = date.getHours()
  if ((hour > 20) || (hour <8)) {
    imeParameterSet("Scale Rules", "early morning scale")
  } else {
    imeParameterSet("Scale Rules", "middle of day scale")
  }
}
          

Example: randomly select a pattern to use for a generator

This is a generator-level Bar trigger script.


function onImeStart() {
  // Get a random integer between 1 and 3 inclusive.
  var value = wjsRandomGetFromTo (1, 3)

  wjsLog ("value=" + value)

  var patternString = ""
  if (value == 1) {
    patternString = "<100 B 240 1>"
  } else if (value == 2) {
    patternString = "<100 B 120 1 120 2>"
  } else {
    patternString = "<100 B 60 1 60 2 60 3 60 4>"
  }

  imeParameterSet("Patterns", patternString)
}
          

Example: script trigger that allows Event Handler Script Functions to emit MIDI CC events, with an optional delay

This is a script that you could use as a cell-level Bar trigger script.


function onImeBar(bar) {

  // Generator trigger...
  // Apply a pan sweep through the bar from left to right,
  // to show-off the use of imeMIDISendCC.
  
  wjsLog ("onImeBar(" + index + ") - Generator")

  var barDuration = imeBarDurationGet()
  
  wjsLog ("barDuration=" + barDuration)

  var midiChannel = imeGeneratorMIDIChannelGet()
  var delay = 0
  var ccController = 10 // Pan controller!
  var value = 0
  while (delay <= barDuration) {
    var value = (127 * delay) / barDuration
    // Note that the "delay" is optional; we're using the in this specific
    // demo, to get a sweep effect from start to end of the bar.
    imeMIDISendCC(midiChannel, ccController, value, delay)
    delay = delay + 20
  }
}
          

Example: cell bar event trigger, that automatically adjusts the mix root and tempo every 2 bars

Example: cell start event trigger, that automatically adjusts the tempo to suit the time of day


function onImeStart() {
  wjsLog ("Mix!")

  // Wotja script to get hour of day as 24-hour clock value
  // ... and adjust tempo accordingly!
  var date = new Date()

}
          

Example: generator start event trigger, that automatically cycles the Chord Depth every time it starts playback


function onImeStart() {
  wjsLog ("Generator!")

  var chordDepth = imeParameterGet("Chord Depth")

  // Convert any string value to integer, then add one.
  chordDepth = parseInt(chordDepth) + 1
  
  // Loop the value around if it gets larger than we want.
  if (chordDepth > 8) {
    chordDepth = 1
  }
  imeParameterSet("Chord Depth", chordDepth)
}
          

Example: generator event trigger, that automatically changes Chord Depth every bar


function onImeBar(bar) {
  wjsLog ("onImeBar, bar=" + bar)
  var chordDepth = imeParameterGet("Chord Depth")

  // Convert any string value to integer, then add one.
  chordDepth = parseInt(chordDepth) + 1
  
  // Loop the value around if it gets larger than we want.
  if (chordDepth > 8) {
    chordDepth = 1
  }
  
  imeParameterSet("Chord Depth", chordDepth)
}
          

Example: bringing generators into the mix

In this example, imagine that you have a mutating drum Generator that you want to have muted at the start of the mix and come in with a bang at the start of bar 20. And you don't want the mutations to start until bar 21...

How would that work in the world of script?

Here is the Generator Start trigger:


function onImeStart() {
  // When we start, disable mutation for this Generator!
  // And set mute, too!
  imeParameterSet("Mute", "Yes")
  imeParameterSet("Mutation Factor", 0)
}
          

Here is the Generator Bar trigger:


function onImeBar(bar) {
  if (bar == 20) {
    // At bar 20, unmute the generator!
    imeParameterSet("Mute", "No")
  }

  if (bar == 21) {
    // At bar 21, adjust the mutation factor!
    imeParameterSet("Mutation Factor", 20)
  }
}
          

The power of using scripts like this, is that:

  • The drums alway start on the bar specified.
  • They don't morph until they are audible.
  • The drum elements can now make staggered entry despite all being on the same MIDI channel.

Example: Emit MIDI CC in response to composed note events


var GLastNote = null

function onImeGeneratorComposed(generatorIndex, noteon, channel, pitch, velocity) {
  // Keep track of last composed note using the global (for this generator)
  // called GLastNote ...
  // Note that the "pitch" parameter should be ignored when noteon is false.

  midiChannel = imeGeneratorMIDIChannelGet()

  if (noteon) {
    if (GLastNote != null) {
      imeMIDISendCC(midiChannel, 11, GLastNote, 10)
    }

    GLastNote = pitch
    imeMIDISendCC(midiChannel, 11, pitch, 0)
  } else {
    if (GLastNote != null) {
      imeMIDISendCC(midiChannel, 11, GLastNote, 10)
      GLastNote = null
    }
  }
}
         

Example: Change TTM Text for Generator At Start of Mix


function makeRandomText() {
  // Make some random TTM text.
  // We show 3 different techniques!
  // Choose one of these to use at random.
  var technique = wjsRandomGetFromTo(0, 2)
  var ttmText = ""

  switch (technique) {
  case 0:
    // Make a string with 3 random words
    ttmText = iteRandomWordsGet(3)
    break
  case 1:
    // Make a string that is a random shuffle of words
    ttmText = "Shuffle these four words"
    ttmText = iteShuffleWords(ttmText)
    break
  default:
    // Make a string that is a random shuffle of characters
    ttmText = "Shuffle these characters"
    ttmText = iteShuffleCharacters(ttmText)
    break
  }

  wjsLog("random ttmText=", ttmText)

  return ttmText
}

function onImeStart() {

  // Generate some random TTM text!
  var ttmText = makeRandomText()

  // Now that we have our string, set it!
  imeParameterSet("Text Pattern Text", ttmText)
}
          

Example: Change TTM Repeats at Start


function onImeStart() {
  // Set the TTM property "Text Pattern Repeats" to 2

  imeParameterSet("Text Pattern Repeats", 2)
}
          

Example: Change TTM Text At Start Then Restore After 4 bars


// Complex scripting example:
// - At mix start, apply random TTM Text.
// - After 4 bars, or at mix stop - restore the original TTM Text.

// The original TTM text is stored in this "global" variable
var GOriginalTTMText = ""

// The value we last set in onImeStart
var GLastSetTTMText = ""

function setRandomTTMText() {
  // Take a copy of the original TTM text
  GOriginalTTMText = imeParameterGet("Text Pattern Text")
  wjsLog("GOriginalTTMText=" + GOriginalTTMText)

  // Make a string with 3 random words
  var ttmText = iteRandomWordsGet(3)
  wjsLog("ttmText=" + ttmText)

  GLastSetTTMText = ttmText

  // Now that we have our string, set it!
  imeParameterSet("Text Pattern Text", ttmText)
}

function restoreOriginalTTMText() {

  var ttmNow = imeParameterGet("Text Pattern Text")
  wjsLog("restoreOriginalTTMText, ttmNow=" + ttmNow)

  if (ttmNow != GLastSetTTMText) {
    wjsLog("The user value has changed since last random set - keep the current value")
  } else {
    wjsLog("Restoring TTM Text to=" + GOriginalTTMText)
    imeParameterSet("Text Pattern Text", GOriginalTTMText)
  }
}

//
// Trigger script functions
//

function onImeStart() {

  wjsLog("onImeStart")

  setRandomTTMText()
}

function onImeBar(bar) {
  // On the 4th bar, restore the TTM text... UNLESS the user
  // has already changed the value through the UI.

  wjsLog("onImeBar, bar=" + bar)

  if (bar == 4) {

    wjsLog("onImeBar, bar 4!")

    restoreOriginalTTMText()
  }
}

function onImeStop() {
  wjsLog("onImeStop")
  // At the end, restore the TTM text... UNLESS the user
  // has already changed the value through the UI.
  restoreOriginalTTMText()
}

Hyperinstrument

What is a hyperinstrument?

A hyperinstrument can be defined as being an instrument that can have extraordinary, semi-automated response to relatively simple real-time inputs.

Wotja is a hyperinstrument in many ways. For example from simple interaction in real-time through mouse and keyboard, you can have it generate extraordinary, ever-changing music that responds to your inputs. Wotja also directly responds to any real-time MIDI note data fed into it, for example from a MIDI keyboard or other MIDI controller; where you feed MIDI data into Wotja, you will find that Wotja can automatically harmonise its generators with all incoming MIDI note data. You can also configure Wotja to respond in many advanced ways to both MIDI note events and MIDI control events (otherwise known as "MIDI CCs").

Wotja can function as a hyperinstrument for 2 main reasons: The IME can real-time harmonise with incoming MIDI note events and control events (otherwise known as "MIDI CCs"), and Wotja's generative engine is an instrument that creates more than the sum of your direct inputs with keyboard, mouse, and MIDI. In other words, Wotja's generative engine, MIDI control, scripting and direct MIDI input harmonisation all work together to make itself greater than the sum of its parts; a customisable generative hyperinstrument!

See the Hyperinstrument - Quick Start if you want to get started quickly.

How does Wotja work as a hyperinstrument?

You can respond to any incoming MIDI CC however you want; for example, to change the current scale or adjust a harmony rule in real-time in response to incoming MIDI CC events.

You can also respond to any incoming MIDI Note on/off event however you want; for example, you could use some notes (such as accidentals in a scale) to change parameter values. In other words, you can use certain specific notes to trigger various complex responses by Wotja, for example; or to enable/disable the chording parameters only for certain notes (immediately that a note is triggered!); or to change scale; or pretty much whatever you can imagine.

Here is an example of a Generator MIDI In Note trigger script that you could use in your own mix.


function onMIDIInNote(channel, noteon, pitch, velocity) {
  if (channel == imeGeneratorMIDIChannelGet()) {
    wjsLog("onMIDIInNote for our channel!")
  }
}
          

Quick Start - Listening generators / Hyperinstrument

To have a Generator "listen" to incoming MIDI data, you need to follow the instructions below.

  1. Set "MIDI Input" to be your MIDI input device.
  2. Set the generator you want to listen to MIDI input, such that:

    • the Generator Type is Listen
    • the MIDI In Script is something like this:
    
    function onMIDIInNote(channel, noteon, pitch, velocity) {
      if (channel == imeGeneratorMIDIChannelGet()) {
        wjsLog ("onMIDIInNote for our channel!")
      }
    }
                  
  3. You might want to set your Listening generator to auto-chord with depth of 2 or greater.

  4. If you want an different Generator to also make sounds in response to your incoming MIDI note event, set it to FOLLOW the Listening Generator.
