I have Mavericks running ableton live sequencing via a Motu XT interface out to my synths.

I tried routing via the software so I could have the PE coming in Midi input 1 on the motu and then in ablteon having that pass through to whatever output of the synth that I wanted to control whihc would also have incoming note-data from ableton.

The synths only receive the note data and the PE does not control the synth params this way.  Please assist or let me know if you require a more in depth explanation.
