[LAD] alsa seq client ids??

hi in an alsa-seq enabled application i would like to automatically connect to all available "hardware" midi devices on startup. however i have found no way to find out, which clients are real midi devices and which are not. my first attempt just connects to everything except itself and client-0 ("system"), which is rather sub-optimal, as it includes the "midi through" which tends to lead to wild midi feedbacks (our application _can_ do midi through too...) unfortunately i haven't found any documentation. what i have found is: - http://www.alsa-project.org/alsa-doc/alsa-lib/group___sequencer.html (saying that "user clients" have ids 128..191; this is fine, to filter out other applications, but not enough for me) - http://alsa.opensrc.org/index.php/Aconnect (which gives a "simplistic guideline for client numbers": 0..63=internal; 64..127==devicedrivers; 128..?==userapps; this would be perfect, but unfortunately this just seems to be outdated information; e.g. i have 4 hw-midi devices connected and they are assigned the numbers 16,20,24,28) any hints? or iam i totally out of my mind for trying to (optionally) a(uto)connect on the application-side? mfg.asdr IOhannes PS: i guess this question might be more appropriate on one of the alsa lists, but since i am subscribed to lad and not to one of these, .... PPS: sorry if this comes through 2 times; i originally sent this email from an non-subscribed account...
