I've just started looking at MIDI stuff in PD, and could use a pointer to some basic information that I'm not seeing in the online help.
I've hooked up a MIDI keyboard (Midiman Oxygen 8) to a laptop (running under Windows for now, since I haven't yet been able to get the USB MIDI to work under Linux). From what I can tell, the built in notein function is monophonic, and only handles "note in" but not "note off" coming in from the keyboard. Is this correct? Is there a way to catch "note off" messages? (If so, that would be a way around the polyphonic issue for what I'm trying to do now.) Is there another way to handle a polyphonic keyboard?
I have a feeling I've just missed something that will be obvious when explained. Thanks for any enlightenment.

Notoff messages also comes in (upon release of a key). You may want to check your setup. The stripnote object it there to actually remove the noteoff messages.

MIDI really is monophonic (only one note at a time). If you put a print object at the outlet of notein you will see that all notes do come in. If you want to build a polyphonic instrument in PD you should take a look at the sampler.poly example in the audio example folder. The poly object takes care of polyphony for you.

[notein] has 3 outlets: pitch,velocity,MIDI channel. A note-off is a note with velocity=0. Maybe you're not monitoring the velocity?

Ah! OK, my MIDI knowledge was rustier than I thought. Looking at the example patch (I haven't written any MIDI-based patches myself yet), I see that it, indeed, is sending the note with velocity 0. This makes things much simpler.
Thanks! (to you and to the several others who responded.)

I use an Oxygen with standard midi-in, but it should work with this driver as a Midisport 1x1, as others have reported on LAD: http://member.nifty.ne.jp/Breeze/softwares/unix/usbmidi-e.html ciao,
