Templates Engine

Examples

In the Resources/Templates folder, you will find default patch files used in Usine. You can modify, adapt those files to your needs.

Create Templates

Usine includes a powerful Templates Engine.
To manipulate and create your own templates you have to understand how work's the internal messages describes below.

To have an idea of how it works, start to open the Usine console-panel by double clicking on the trace-panel.

Then open a patch and drag&drop a file.

You will see several lines added in the console, something like

SET_VAR patch SENDER_PATCH = noname
SET_VAR integer MOUSE_X = 150
SET_VAR integer MOUSE_Y = 189
SET_VAR integer CONTROL_PRESSED = 0
SET_VAR integer SHIFT_PRESSED = 0
SET_VAR integer ALT_PRESSED = 0
SET_VAR integer ON_WIRE = 0
SET_VAR integer SRC_TERM_IN_OUT = 0
SET_VAR String DROP_FILENAME = /Applications/Usine.app/Usine Library/Audio FX/Delays/Delay.pat
SET_VAR String DROP_FILEEXT = pat
SET_VAR integer SRC_MODULE_ID = 1
SET_VAR String DROP_SHORT_FILENAME = Delay

If you now try to create a wire on the patch, you will see in the console :

SET_VAR integer CONTROL_PRESSED = 0
SET_VAR integer SHIFT_PRESSED = 0
SET_VAR integer ALT_PRESSED = 0
SET_VAR integer MOUSE_X = 233
SET_VAR integer MOUSE_Y = 432
SET_VAR patch SENDER_PATCH = /Applications/Usine/Usine Library/Audio FX/Delays/Delay.pat
SET_VAR integer SRC_TERM_NUM = 1
SET_VAR integer SRC_MODULE_ID = 9
SET_VAR integer SRC_TERM_IN_OUT = 2
SET_VAR module SRC_MODULE =  
SET_VAR integer ON_WIRE = 0

Those values are interpreted by the template engine to offer several choices to user after a wire creation or what to do with a dropped file.

In the folder Templates you will find lots of examples (files *.txt) that you can easily adapt to you own purpose like

Internal Messages Language (IML)

Since the v4.1 Usine provides a powerful internal language to create patch dynamically.

The background idea is very simple: you send messages to the internal messages manager by several ways:

• use the patch-send-internal-msg module
• use the SendInternalMsg in scripts
• use the SDK.

Of course, commands can be sent over the network with OSC modules.

Global variables

TARGET_PATCH

Contains the patch designed as the target patch, in other word it's the patch that executes the commands.

SENDER_PATCH

Contains the patch which actually sending the messages. This variable is automatically set by Usine.

MOUSE_X

Contains the current X coordinate of the mouse. This variable is automatically set by Usine.

MOUSE_Y

Contains the current Y coordinate of the mouse. This variable is automatically set by Usine.

SHIFT_PRESSED

Its value is 1 if the user is pressing the [shift] key, 0 otherwise.

CONTROL_PRESSED

Its value is 1 if the user is pressing the [control] key, 0 otherwise.

ALT_PRESSED

Its value is 1 if the user is pressing the [Alt] key, 0 otherwise.

LAST_CREATED_MODULE_NAME

Contains the name of the last created module by the command CREATE_MODULE. This variable is automatically set by Usine.

ON_WIRE

Its value is 1 if the user has dropped a file on a wire.

BUSES_LIST_DATA

Contains the list of all available DATA buses for the current patch.

BUSES_LIST_AUDIO

Contains the list of all available AUDIO buses for the current patch.

BUSES_LIST_MIDI

Contains the list of all available MIDI buses for the current patch.

CREATE_MODULE modulename id x y [filename] [queryindex]

Creates a new module at the position x y in the patch.

The module type is set by the parameter id (see the list of id's bellow). Then the module is renamed with the modulename.

For subpatches modules (id=6) you must specify the filename of the subpatch.

For user modules (id=95) you must specify the user module filename.

You can also set the queryindex, which is the value of the choice order in the query creation box. ie:for audio modules 0=mono, 1=stereo, 2=4 x channels, etc.

CREATE_MODULE vol 4 100 100  creates an audio volume stereo module
CREATE_MODULE vol 261 100 100 2  creates an audio volume 4channels module (queryindex=2) 
CREATE_MODULE gate 6 100 100 'c:UsineGate.pat'  add the Gate.pat subpatch
CREATE_MODULE matrix 95 100 100 'Matrix.usr'  create the Matrix.usr User module 
CREATE_MODULE reverb 95 100 100 'Reverb.usr' 0  create the Reverb.usr User module in Mono version (queryindex = 0) 

CREATE_PLUGIN modulename x y 'plugfilename'

Creates a new plugin module (for example VST) at the position x y in the patch.

CREATE_PLUGIN myplug 100 100 'ACE(x64).plugin'

RENAME_MODULE oldmodulename [newmodulename]

Changes the name of the module. If the newmodule name parameter is missing, the module name is set to nothing (blank).

RECREATE_MODULE modulename

Recreates the modulename module.

DELETE_MODULE modulename

Deletes the modulename module.

SET_TARGET_PATCH patch

Defines the target patch which will receive Internal Messages

SET_TARGET_PATCH SENDER_PATCH  the active patch is the current patch

SET_TARGET_PATCH subpatchname

CREATE_MODULE MyMIDICreate 78 100 100  //create a Create MIDI note module
SET_VALUE MyMIDICreate create 1  //set the ‘create' inlet of the ‘MyMIDICreate' module value to 1
...
CREATE_MODULE MyDelay 54 100 100  //create a Delay module
SET_VALUE MyDelay delay 100  //set the delay inlet of the ‘MyDelay' module value to 100ms

CREATE_LINK moduleSrcOut terminalSrcOut moduleDestIn terminalDestIn

CREATE_LINK moduleSrcOut termSrcOutNum moduleDestIn termDestOuNum

Adds a new link (wire) between two modules. Always from out to in.

CREATE_LINK Step1 out Delay1 delay

The CREATE_LINK command can also be used with Terminal order number instead of terminal names. Typically, the SRCTERMNUM gives the order of the target inlet. The following example comes from a template (see p226).

CREATE_LINK in1 in SRC_MODULE SRC_TERM_NUM

DELETE_LINK moduleSrcOut terminalSrcOut moduleDestIn terminalDestIn

Deletes a link (wire)

DELETE_LINK Step1 out Delay1 delay

Az above the DELETE_LINK command can also be used with Terminal order number instead of terminal names.

CLEAR_PATCH

Clears the target patch. No prompt is made.

STORE_FOR_UNDO

Stores Undo information's. So the user will be able to cancel the last operation.

For example, if you send the single command

CLEAR_PATCH

Then undo is impossible...

Now, if you send

STORE_FOR_UNDO
CLEAR_PATCH

The user will be able to undo the Clear patch operation.

UNDO_PATCH

Executes an undo on the target patch

REDO_PATCH

Executes a redo on the target patch

LOAD_PATCH filename

Loads a new patch in the target patch. Be careful, no prompt for save is done…

SAVE_PATCH filename

Saves the target patch as a new name

RELOAD_PATCH

Reloads the current Target patch.

RENAME_PATCH newfilename

Renames the target patch without saving it.

LOAD_RACK filename

Loads a new rack in the current workspace. Be careful, no prompt for save is done…

ADD_GROUP filename X Y

Opens a patch and add new modules to the actual patch (without clear it before).

INPUT_QUERY_VALUE textToDisplay VarName DefaultValue

Ask the user to enter a numerical value and stores the result in VarName.

SET_TARGET_PATCH SENDER_PATCH
INPUT_QUERY_VALUE 'Enter the fader value' FADERVALUE 50
SET_VALUE FA1 fader FADERVALUE

INPUT_QUERY_STRING textToDisplay VarName DefaultValue

Ask the user to enter a string and stores the result in VarName.

SET_TARGET_PATCH SENDER_PATCH

SET_COMMATEXT LB1 list COMMATEXT

INPUT_QUERY_LIST WindowTitle Question List ResultStringVariableName ResultIndexVariableName(optional)

Generally used with the following variables:

• BUSES_LIST_DATA
• BUSES_LIST_AUDIO
• BUSES_LIST_MIDI

For example

SET_TARGET_PATCH SENDER_PATCH
