Re: [PD-dev] midiout

There's already a sysexin so sysexout makes sense.

I can help testing it on Os X.

I agree it's a bug. So far I've done a simple c program that outputs the sysex correctly, so I would be able to patch. The thing is that if we keep midiout object we need to change it's interface (because it would have to accept a list instead of a float). So maybe better to create a new object sysexout?

PS: On the other hand I need some help building/configuring, I open another thread...

    Hi.
    I've been trying to use midiout but it does not work when
    sending sysex
    because it sends 1 byte at a time.
    Chatting with matju on #irc where he showed me the source
    code, I think
    the problem is that midiout uses ultimately
    sys_alsa_putmidibyte to send

    snd_seq_ev_set_sysex(&ev,1,&data)

    one byte at a time

    So we thought about writing an external that uses alsa-midi
    functions
    and he guided me the first steps.
    Now, the problem is that this external would need access to
    structure
    midi_handle, and variables alsa_midioutfd and alsa_nmidiout
    which are
    defined in s_midi_alsa.c (because creating and opening ALSA
    ports is
    handled there). The functions provided by s_midi are not good
    enough as
    I need to

    snd_seq_ev_set_sysex(&ev, data_array_size,data_array)

    So my question is: is it possible to write such external? or I
    need to
    patch the sources?


IMHO this is a bug, so you should patch the source, then submit
the patch to the tracker. Also it seems to bug differently on
different OSs, only linux uses alsa. Pd's sysex implementation
didn't work properly on WIN32 either last time I checked.
