Hi,
I've read about SysEx continuations aka. divided SysEx http://www.allegro.cc/forums/thread/607445 http://www.sonicspot.com/guide/midifiles.html
What it means is that within a MIDI file, a long sysex could be split across several events with different delta times, giving the receiver some processing time in between (e.g. flash EEPROM etc.). The delta times tell when to send the parts.
Now, is that truth? How to do that with ALSA? The documentation on snd_seq_ev_set_sysex insists: "the sysex data must contain the start byte 0xf0 and the end byte 0xf7." http://www.alsa-project.org/alsa-doc/alsa-lib/group___seq_middle.html#ga1048...
Would it be the sole business of the low-level ALSA driver to slowly send large (and complete) sysex data, out of application control (e.g. the delta times would get lost)?
Should apps always coalesce partial sysex data and hand out the complete blob to ALSA's snd_seq_ev_set_sysex?
Is divided SysEx too rare to worry about?
I'm asking because we've seen a user of Wine & KORG stumble upon a non-F7-terminated SysEx.
