connection to a synthetizer

Anything that doesn't fit into other topics goes here!
Hello!
I discovered LMMS about a weeks ago, and I really like it!
But I would like to know if it's possible to connect an external keyboard ( a PSR E313 from YAMAHA, with MIDI input and output plugs ) to use it into LMMS to produce music.
If possible, could someone please explain me how to?

Thanks in advance for your answers ;)
LMMS does not yet have midi out.

Futher more if they are the, what I call real midi plugs , how are you gonna connect those to your pc?
You would need a soundcard with midi connections, but

LMMS can record midi, through usb, so if the yamaha has an usb connection, its simple. ( assuming you're pc has an usb port)

Midi out (from lmms) is on the request list. Would be awesome, but it can't be done yet.

If only Atari ST was still around. :P
1980 midi in and out (no through)

And how to connect:

I have no idea though, if this works with the cable I showed above.
And you can do this on all instuments, like the triple oscillator and also vst.
Welcome to LMMS forums, I just posted the same video and deleted it.
