sending single notes around...

i want to send single note (note on + note off).. i tried this:

[0000:00]> dnew 0 "24:0" wo
[0000:00]> tnew traka
[0000:00]> taddev 0 0 0 {non {0 1} 49 120}
statelist_done: non {0 1} 31 78: unterminated frame
[0000:00]> taddev 0 0 1 {noff {0 1} 49 64}
[0000:00]> p
[0000:02]> s

24:0 is alsa's 24:Virtual Raw MIDI 2-0

for monitoring i did:
amidi -p hw:2,0 -d

and it shows these notes:
91 31 78
91 31 00

both korg padKontrol and korg electribe send this to trigger sound on electribe:
99 31 78
89 31 40

am i doing something wrong? how would you send single notes around?
