Hello!
If I want to output a MIDI note to all channels, what do I have to assign to
snd_seq_event_t *ev;
ev->data.note.channel
Is there a possibility to do so in one strike, or do I ave to iterate
through all 16 channels?
Kindest regards
Julien

I think it's up to your MIDI destination to ignore the channel
information (so called 'omni' mode) is it not?

Thanks Jens, Victor. BUT: There are a few softwaresynths I can't properly
control or even a few of my hardware pieces, because there such options are
hidden deep within some menus.
So: Can I build/enhance a MIDI-router application to do this for me? Would I
really have to rely on just iterating through all possible output_channels?
Or is there a way to drop the channel information from a snd_seq_event_t, so
all channels must receive it, for lack of absolute information?
Kindest regards

For your hardware it is very likely that you can set omni mode remotely.
Its in the spec, wait a sec ...
For each channel do
Controller 125 (with value zero) for omni on
Controller 124 (with value zero) for omni off
In both cases an all-notes-off is implicit.

Hello!
Thanks for the info Jens. I didn't even suspect, that this is standardised.
Kindest regards

Hi,
If you don't mind an extra component, you can easily do this in pd,
csound, etc...
Cheers,
Andrés

AFAIK, yes. Midi receivers can be set to ignore the
channel (omni mode) but there's no such thing as
midi command without a channel number (except for
the system commands).
For the ultimate in MIDI routing & mangling, have
a look at <http://das.nasophon.de/mididings/>
Fully text based, you just need to know some Python.

Thanks again all of you. I now found my solution.

there is no code in MIDI for "all channels".
