The best and perhaps easiest way to get sample-accurate timing would be to support JACK MIDI, which is in the currently-released JACK, and will be in the 1.0 JACK release too. This will also enable a very cool feature: with JACK MIDI, one can dump an entire MIDI-based sequence to a wav file, in "freewheeling mode" (faster than RT), in sync with audio tracks using a DAW, an excellent feature for dumping mixes. The JACK MIDI API is also reported to be easier and saner than ALSA, and more reliable, and sample-accurate using the same clock as JACK transport. - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGagFme8HF+6xeOIcRAs6RAJ4nqVBO9j1MUmjH0pDBDkkM7CK8WACgknnA kToXusjZxlLoJZSYDGTQstg= =RHFL -----END PGP SIGNATURE----- _______________________________________________ fluid-dev mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/fluid-dev
