I finally wanted to get rid of any board and use the FM3 by itself 5and just add when I need my midi expression pedal as I use the 4 stand in switch).
I came with this solution. I designed the enclosure for what I called date FS Extender and printed it with a high quality material.
I did a left side and right side, but Finally kept only the left side.
It is screwed to the FM3 with original screws, it has a pot to change the light intensity of the switches LEDs and it is power dvia FAS Link (like th midi expression pedal when used).
The M-Vave is connected to my phone to start backing tracks with ST3 and ST3 is programed also to change prestes and scenes based on time stamp.
But I change a song on the FM3, it also change in ST3 as it is connected too via the WIDI JACK
So full duplex sync.
Quite happy with the setup and still very portable.
