I'm currently writing an application that will be able to 'auto subscribe' itself to a certain sequencer client when that client becomes available to the system. I want (for example) to be able to plug in a USB MIDI interface, and when I do that then my application detects this and does a subscription on it, just like aconnect would do.
A possible solution is polling; every second or so, i could generate a list of clients with snd_seq_query_next_client and look for a certain client name (libpcre comes to mind here;), but I was wondering if there is a better solution? ..in other words, is it possible to get such events from the system in a similar way like one would receive regular MIDI events?
Subscribe to SND_SEQ_CLIENT_SYSTEM:SND_SEQ_PORT_SYSTEM_ANNOUNCE. Try "aseqdump -p 0:1" to see what events you get.
