[LAD] Session Handlers and 'level 1' support

Hi, I don't know who locked himself up after the 'LADI' discussion to actually write an session handler for Linux. :) But in meantime Ladish has added 'level 1' support: "When ladish studio is being saved, applications that are run at level 1 receive the SIGUSR1 UNIX signal. In signal handler function, a global variable can be set to mark that save is needed. On next main loop iteration, the global variable is checked and eventually save is made. Save of the internal state can be made in a fixed file path, but it is more useful to supply the file path through commandline. When starting, app loads its internal state from the file specified. When saving, app saves its internal state to the file specified." http://ladish.org/wiki/level1 Ams, Jack_Mixer and calfjackhost (in progress) has already added level 1 support, and it seems to work OK (all though there are some improvements ahead). An advantage compared to 'LASH' or 'Ladish' support seems to be that level 1 is pretty easy to implement by the application developers. Now I'm wondering whether this 'level 1' could be a point of agreement between different (potential) Session Handlers for Linux. If other Session Handlers also adds 'level 1' support, it would make the implementation of more then one Session Handler more easy and less problematic for the Linux Audio world in my opinion. What do you think? Regards, \r
