conn_jack

Classes for managing jack client connections.

These differ from the JACK Client for Python (jack), in that it makes possible connecting and disconnecting ports which are not "owned" by a client created in your process.

There is also an (optionally installed) QtJackConnectionManager which emits signals when events of interest happen. In order to use the QtJackConnectionManager class, you must install with the "[Qt]" option, like so:

$ pip install conn_jack[Qt]

Using the plain (non-Qt) version

Import JackConnectionManager:

from conn_jack import JackConnectionManager

Create an instance using standard constructor syntax ...

self.conn_man = JackConnectionManager()

... or use it as a context manage:

with JackConnectionManager() as conn_man:

The non-Qt version uses callbacks to inform your program when events of interest happen. Register your functions as callbacks using the "on_" methods:

self.conn_man.on_client_registration(self.jack_client_reg)
self.conn_man.on_port_registration(self.jack_port_reg)
self.conn_man.on_shutdown(self.close)

Using the Qt version:

In order to use the Qt version, you must import "QtJackConnectionManager" from the conn_jack.qt module.

from conn_jack.qt import QtJackConnectionManager
self.conn_man = QtJackConnectionManager(client_name = "DescriptiveClientName")

The Qt version forsakes callbacks for the Qt signal/slot mechanism. To subscribe to signals which are generated on events of interest:

self.conn_man.sig_client_registration.connect(self.slot_client_registration)
self.conn_man.sig_port_registration.connect(self.slot_port_registration)
self.conn_man.sig_shutdown.connect(self.slot_shutdown)

Refer to the help text to determine the function arguments to use in the callbacks or slots.
