I think this wasnt clear enough, let me rephrase it better. Sysex is basically meant for users, so using sysex brings the following problems: -It's harder from the developer standpoint to do this, specially from their app. It's harder to code, much less abstracted (since he's not supposed to manage sysex code at driver level) Instead of just using a few simple library calls, he has to capture the input sysex calls, and parse it. And, also being myself such a fan of how clean the alsa sequencer api is, this would be torture ;). Also more annoying for driver developers who instead of just sending the info, they have to encoding as sysex. -It's useless for the user. This is not some kind of sysex you use to set patches or something like that. It's sysex for retrieving information that "interferes" with the normal way you communicate with the driver, so the user has access to things that there isnt any point in it having access to. So, thats why I really think the sysex approach is overcomplicated, kills the clean interface to the alsa sequencer, and since it's only for alsa, it definitively has no point in being there. A library call is simpler to use, simpler to write, and fits much nicer with the overal sequencer api. I know that probably many of you think this is not the right approach just because of the fact that it hasnt been done before in audio APIs. But this only because of midi limitations that no one attempted this. It's only starting to be done recently, and one of the better examples is Steimbergs VST and Sonar's DXi, which both finally allow for this (Althought I dont like the way those apis work since they force you to run an instance of the program per channel) All in all, i think this HAS to be a library call, it's not some extra useless thing, and I'm sure that any programmer of sequencer programs will like to make use of it, as much as users will like the result. (And I'm telling you this from my perspective which is both user and app programmer) regards Juan Linietsky > regards. > > Juan Linietsky > > _______________________________________________ > Alsa-devel mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/alsa-devel > _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
