Sorry for the late reply. I think you will need to connect your MIDI
controller keyboard as an output MIDI device for that to work. Usually
d-OutputMidi is sending the message to fluidsynth which synthesizes the
audio and sends that to portaudio.
I'm not sure if you can connect your controller to both MIDI-input and
MIDI-output, I expect you can, but when connecting it as an output MIDI
device you will need to use something (Alsa or Jack) as the connection,
because direct control of MIDI output devices is not done by Denemo
currently. 
(It is a curious coincidence that there was some unused code in Denemo
to operate a queue of messages for a MIDI out device, and I think the
preferences still offer to connect a MIDI device for output, but this
was dropped from the code only last week - it wasn't actually getting
called).
