In which timing? Those two SysEx messages are the (immediate) response to the initialisation string. The first seems some generic "yes, bay attached, speaking protocol 2.3" reply, while the second is your initial jack status. You could time out on not receiving the "bay attached" message and then not enable your SysEx listener at all. The actual message will arrive within a single second, but 5 seconds should be a safe bet. Once this sequence completes, you will then get jack/button/volume updates as the event occurs on the bay. To confirm, the initialisation string is: echo -en "\xf0\x00\x20\x21\x61\x00\x00\x00\x7f\x00\xf7" > /dev/snd/midiC0D1 > thanks, > Takashi Regards, Tony V. --=-YpnNdURY6QEIVN1VdhXu Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEABECAAYFAkhqBoAACgkQp5vW4rUFj5rhgwCgjJAODRgaRrIb4QUZpocJpBkZ xTkAnj32xs1Eq6x8N/xanj357IdekFvG =x+X5 -----END PGP SIGNATURE----- --=-YpnNdURY6QEIVN1VdhXu-- --===============5498888740678326048== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel --===============5498888740678326048==--
