| − | FTM is a shared library for Max/MSP providing a small and simple real-time object system and optimized services to be used within Max/MSP externals. | + | * [[A brief introduction to FTM]] |
| | + | * [[Credits]] |
| | | | |
| − | The main purpose of FTM is the representation and processing of sound, music and motion capture data in Max/MSP extending the data types processed and exchanged by the Max/MSP objects.

| − | == Data Structures ==
| |
| − | | |
| − | FTM allows for static and dynamic creation of complex data structures. The following classes are currently implemented and documented:

| − | FTM objects can contain references to other FTM objects. A simple garbage collector handles transparently the destruction of dynamically created FTM objects referenced by multiple elements of a patch. | |
| − | | |
| − | Static FTM objects are created in a patcher using a dedicated Max/MSP external called ftm.object.
| |
| − | They can be named within a local or global scope and marked persistent to be saved within the patcher. FTM provides a serialization mechanism to recursively save the content of objects and the contained objects.

| |
| − | | |
| − | FTM externals can refer to FTM objects and dynamically create objects. FTM objects can be sent in lists or as single values using a dedicated FTM object message.
| |
| − | | |
| − | While basic operations of FTM objects are implemented as methods of the FTM classes, more complex interactions with FTM objects use operators in form of Max/MSP externals.

| − | == Operators ==
| |
| − | | |
| − | FTM comes with an extended message box - the ftm.mess external - which integrates classical Max message syntax with FTM names, infix expression evaluation, function calls and method invocation including return values.
| |
| − | | |
| − | [[Image:About.ftm.mess.gif|frame|examples of the FTM message box]]
| |
| − | | |
| − | Apart from ftm.object and ftm.mess, FTM includes a set of externals implementing basic functionalities such as iteration, playing, interpolation, etc. and the conversion between FTM objects and Max values or lists.

| − | [[Image:About.ftm.operators.gif|frame|example of FTM externals operating on FTM objects (the MIDI parsing objects convert a MIDI byte stream into a stream of FTM MIDI events)]]
| |
| − | | |
| − | Operators specific to a certain field of applications are assembled to separate object sets such as Gabor for sound analysis/resynthesis and MnM for mapping and recognition techniques.

| − | == Editors and File Formats ==
| |
| − | | |
| − | The editors for FTM objects are implemented in Java and integrated into Max/MSP using mxj. Simple double-clicking on an FTM object in a patcher opens its editor.
| |
| − | | |
| − | [[Image:About.ftm.trackeditor.gif|frame|screen shot of the track editor for score objects]]
| |
| − | The communication between FTM objects in a Max/MSP patcher and their Java editors is hidden by the FTM library. By using a transfer protocol such as OSC the GUI could be easily detached from Max/MSP to allow for the distribution of patches and editors among multiple machines.
| |
| − | | |
| − | FTM currently supports simple text files and standard MIDI files. Import and export of SDIF files is currently being finalized and a score interchange format such as MusicXML will be supported in the near future.
| |
| − | | |
| − | Most of these import and export methods are implemented for the FTM track class as it provides a generic container for temporal sequences.

| − | == FTM and Jitter ==
| |
| − | | |
| − | From a certain point of view one can look at FTM as something like Jitter. Like Jitter, it is a shared library installed next to the Max/MSP application. Like Jitter, it extends the set of things one can send through the connections and process by Max/MSP objects.
| |
| − | | |
| − | A bridge between FTM and Jitter converts FTM matrices into Jitter matrices and vice versa (from FTM 2).
