setting up soundtower's tetra vst editor with mpc soft?

Hi everybody, first of all please be patient with my english as its not my native language, sorry

just got an mpc studio and im trying to use it along with my dsi tetra, im using the soundtower vst editor but as everything is fine when using the tetra with track type set to midi in mpc software, when using it in plugin mode, nothing happens, theres no sound nor midi signals.

i have the tetra midi-in connected to a maudio midisport 2x2 midi-out, the mpc studio's midi out to the midisport's midi-in and a lpk25 keyboard usb to the pc

so in mpc software preferences, i've it like this:



when loading the soundtower vst, it has a midi conf that i set like this:



and theres no even midi signal from the mpc or the lpk25 to the midisport

so, has anyone try this setup before? could someone give a helping hand?

thanks,
