Jacko Midi In fails?

[tjingboem]

all examples for the Jacko opcodes have been updated, the note that Jack daemon should run and no -+rtaudio=jack in CsOptions has been added as well,
but there is an issue with the Jacko Midi In connection. In that it does not work.
My keyboard is generating notes, and i think i am using the right kind of code in the csd but there is no sound generated.

; The example shows how to connect a Midi port (Edirol) to the Midi In of Instrument 1

JackoInit   "default", "csound6"		       	        ; Csound as a Jack client
JackoMidiInConnect "UM-3:midi/playback_2", "midiinEDIROL" 	; create 1 Midi in port
JackoAudioOutConnect  "audioout", "system:playback_1"

instr 1	; get notes to the EDIROL Midi port	
midinoteoncps p4, p5
print p4
;print p5

kvel = p5/127
aout    vco2    kvel, p4
JackoAudioOut "audioout", aout
endin
