not to appear too snobbish, but this is linux, and we don't do stuff like that in the kernel. at this time, there isn't any equivalent of OMS-like filtering for the ALSA sequencer, but its pretty simple to write a sequencer client that collects all the data and represents some or all of it at its own sequencer port(s). you would then connect other applications to the filter's ports, and see a filtered version of the MIDI stream. > How can I use the piano to control the computer ? >(while I am recording, or some third app is consuming >the MIDI stream on its own, and I have no control over >that app) the sequencer can multiplex MIDI data to multiple clients. several clients can connect to the same sequencer port, and they will all see the data. i don't know that this scales to very large multiplexing systems, but it will certainly work fine for a few clients. --p _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
