Jack Session Management

When a project uses more than one JACK application, a session manager will help by automatically starting all applications needed for a project and making any connections in JACK needed as well.

In order for the session manager to do it's job, it needs a "clean" system with no jack connections made. However, many applications auto connect on startup to the system inputs and outputs 1 and 2. Other applications will make more connections on startup. JACK provides a Self Connect Mode that can prevent an application from making these connections.

Connect Mode has five modes:

• Don't restrict self connect requests is the default mode for JACK. JACK allows any client to make any connections.
• Fail self connect requests to external ports only will allow a client to connect it's own ports only to ports that are not hardware but will fail to connect to hardware ports. A fail means the application is aware the connection was not made.
• Ignore self connect requests to external ports only will silently ignore requests for an application to connect its own port to hardware port.
• Fail all self connect requests will not allow a JACK client to connect any of it's own ports and will respond with a fail.
• Ignore all self connect requests will silently ignore a JACK clients request to connect it's own ports.

There are also three convenience buttons to start session manager controls. There have been a number of session managers for Linux but the one that seems to have remained is NSM. The original Non Session Manger was a part of the Non group of applications, but because of licensing issues was not packaged for many distributions. Development also slowed down and bugs were not being fixed. However, more applications are "NSM ready" than any other session manager. Raysession was started for this reason as a reimagined NSM controller followed by the New Session Manager which was Non Session Manger ported from NTK to FLTK and with bugs fixed and some enhancement. Then Agordejo was developed as a modern graphic interface to go with New Session Manager.

• Agordejo sets itself as the main graphic user interface to the New Session Manager. It was developed by the same development team as the New Session Manager.
• RaySession is another session manager that uses the same interface as New Session Manager.
• New Session Manager will start the legacy NSM GUI ported to FLTK.
