Thank you, I'll have a look in this.
What I can't understand is if it is possible, with the jack API, to
actually *create* midi note on/off messages. The examples I've seen
(like midimon too, it seems to me) only handle (reroute etc.) midi
coming from other sources, like an external keyboard or another program.
In my case instead I'll have to actually create those messages, as for
example midi sequencers do.
May this is the reason why programs that generate midi (seq24 for
example) use alsa? (see my confusion in point 1) in first message)
