Does that mean, i have to do following:
1.) open sequencer
2.) create my own port on client
3.) subscribe sender=my port receiver=midi device
4.) create events set source to my client/port destination=midi device
5.) send events
is this the correct way of doing it ?
are there some extra things, which are not neccessary ?
