How to connect MC6 with HX Stomp and Collider

Hello and thanks for allow me to participate here.

I purchased a MC6 MKII and I’m trying to use it with my HX Stomp and SA Collider. It seems to be working good, but I can’t get bidirectional communication between MC6 and HX Stomp.
My connection scheme is MC6 Out to HX Stomp In, HX Stomp out to Collider In, Collider Out to MC6 In.
Is this a right scheme?, how must I configure MIDI Thru in each device?
