Detailed Description

OSC Server implementation.

Open Sound Control (OSC) is a protocol for communication among programs, computers, and hardware, like synthesizers or multimedia devices, via networking protocols such as UDP or TCP. It can be thought of as a replacement for the MIDI protocol with rich benefits, like supporting symbolic and high-resolution numerical argument data, providing an URL-style naming scheme in combination with a pattern matching language, and allowing to bundle messages for a better handling of timing and simultaneous processing.

The OscServer class provides an implementation of an OSC server running in a separate thread and handling all incoming and outgoing OSC messages send to or from Hydrogen. Its naming scheme starts with the prefix /Hydrogen/ followed by the name of one of the handler functions implemented as members of this class without the _Handler() prefix. Sending an OSC message to the path /Hydrogen/PAUSE will thus trigger the PAUSE_Handler() to pause the playback. You can play with these features using the command line program oscsend on UNIX-based systems.

Internally, the OscServer is implemented as a singleton and will be created using create_instance() and queried using get_instance(). Using start() all handler functions will be registered to their corresponding paths and the OSC server thread will start to listen for incoming messages. But this will only happen if H2Core::Preferences::m_bOscServerEnabled is set to true. In addition, Hydrogen will send OSC messages about its current state to all clients each time its state changes if H2Core::Preferences::m_bOscFeedbackEnabled is set to true. H2Core::Preferences::m_nOscServerPort contains the port number the OSC server will be started at.

Please note that the way generic_handler() is implemented, the additional registration of commands without argument to require a float input, and the usage of float arguments instead of int are all because of the limitations of TouchOSC.

Catches any incoming messages and display them.

It is also responsible for catching OSC messages at the following paths and invoking the corresponding functions (if only a single argument is present.)

/Hydrogen/STRIP_VOLUME_ABSOLUTE/[x]
/Hydrogen/PAN_ABSOLUTE/[x]
/Hydrogen/PAN_ABSOLUTE_SYM/[x]
/Hydrogen/PAN_RELATIVE/[x]
/Hydrogen/FILTER_CUTOFF_LEVEL_ABSOLUTE/[x]
/Hydrogen/STRIP_MUTE_TOGGLE/[x]
/Hydrogen/STRIP_SOLO_TOGGLE/[x]

[x] Digit specifying a particular instrument.

Parameters

path	The OSC path to register the method to. If NULL is passed the method will match all paths.
types	The typespec the method accepts. In Hydrogen handler functions are registered to listen for floats.
argv	Pointer to a vector of arguments passed by the OSC message.
argc	Number of arguments passed by the OSC message.
data	Unused.
user_data	Unused.

Returns: 1 - means that the message has not been fully handled and the server should try other methods

◆ get_instance()

static OscServer * get_instance ( )

inlinestatic

Returns a pointer to the current OscServer singleton stored in __instance.

Definition at line 123 of file OscServer.h.

◆ handleAction()

void handleAction ( std::shared_ptr< Action > pAction )

Function called by H2Core::CoreActionController::initExternalControlInterfaces() to inform all clients about the current state of Hydrogen using OSC messages send by Hydrogen itself.

The following feedback functions will be used to describe the aforementioned state:

[*] Function will be called for all Instruments in H2Core::Song::__instrument_list.

The constructed messages will contain the Action::parameter2 of pAction as float types (or Action::parameter1 for the actions TOGGLE_METRONOME and MUTE_TOGGLE) and will be associated with one of the following paths:

/Hydrogen/MASTER_VOLUME_ABSOLUTE
/Hydrogen/TOGGLE_METRONOME
/Hydrogen/MUTE_TOGGLE
/Hydrogen/STRIP_VOLUME_ABSOLUTE/[x]
/Hydrogen/STRIP_VOLUME_RELATIVE/[x]
/Hydrogen/PAN_ABSOLUTE/[x]
/Hydrogen/PAN_ABSOLUTE_SYM/[x]
/Hydrogen/PAN_RELATIVE/[x]
/Hydrogen/STRIP_MUTE_TOGGLE/[x]
/Hydrogen/STRIP_SOLO_TOGGLE/[x]

[x] The last part of the URI is determined by Action::parameter1 and specifies an individual strip.

Only called if H2Core::Preferences::m_bOscServerEnabled is true.

Parameters

pAction Action to be sent to all registered clients.

Definition at line 1096 of file OscServer.cpp.

◆ incomingMessageLogging()

int incomingMessageLogging	(	const char *	path,
		const char *	types,
		lo_arg **	argv,
		int	argc,
		lo_message	data,
		void *	user_data )

static

Definition at line 149 of file OscServer.cpp.

◆ init()

bool init ( )

Registers all handler functions.

The path the handlers will be registered at always starts with /Hydrogen/ followed by the name of the handler function without the suffix _Handler. PLAY_Handler() will thus be registered to /Hydrogen/PLAY.

Most handler will be registered for both types "" and "f" (floats). But the following handlers will be registered for floats only:

BPM_DECR_Handler()
BPM_INCR_Handler()
MASTER_VOLUME_ABSOLUTE_Handler()
MASTER_VOLUME_RELATIVE_Handler()
STRIP_VOLUME_RELATIVE_Handler()
SELECT_NEXT_PATTERN_Handler()
SELECT_ONLY_NEXT_PATTERN_Handler()
SELECT_AND_PLAY_PATTERN_Handler()
PLAYLIST_SONG_Handler()
SELECT_INSTRUMENT_Handler()

In case of the session managing handlers the following ones only work with no argument present

SAVE_SONG_Handler()
SAVE_DRUMKIT_Handler()
SAVE_PREFERENCES_Handler()
QUIT_Handler() and others only work by supplying a string "s" type message
NEW_SONG_Handler()
OPEN_SONG_Handler()
SAVE_SONG_AS_Handler()

The generic_handler() will be registered to match all paths and types.

In addition, a lambda function will be registered to match all types and paths too. If the client has not sent any message to Hydrogen yet, it will take care of its registration to m_pClientRegistry using the address of the received OSC message. More importantly, it also will call H2Core::CoreActionController::initExternalControlInterfaces(), which, apart from MIDI related stuff, use handleAction() to push the current state of Hydrogen to the registered OSC clients. This will happen each time the state of Hydrogen does change.

Returns: true on success.
