MC6 pro not responding anymore as soon as i set up an aux switch

Hi there,

my goal for now is just to use my boss fs-7 to set tap tempo and send it to the mc6 pro, which will then send it to the enzo x and chroma console.

But as soon as i set the omniport as aux switch, the swithces on the MC6 pro itself stop reacting to anything. And in the midi monitor i can also see that no midi info is sent out/generated.

It even made the names of my banks in the editor left side of the screen disappear (all become ‘Empty”, though the pages names on the right side remained…). As soon as i disconnected the FS7, the banks names came back, without doing any reset or anything.

What am i doing wrong ?

Here is my controller setting :

But it did not work either if i set up the RING and TIP+RING to ‘do ‘nothing’.

I found a similar post on the forum, but then it seems the solution was to download a new formware (but that years ago, so now i m using the correct firmware), hence my question again.

It’s most likely the fs7. The MC is compatible with foot switches which are momentary and normally open (NO). The fs7 can be configured to be latching or momentary normally open or momentary normally closed. Set the dip switches of the fs7 to ‘momentary’ and ‘polarity II’ (=NO).

Use a 6.3 mm (1/4”) trs cable to connect the A&B port of the fs7 to the MC.

If it is not set up correctly it might cause the MC to hang because the controller reads the fs to be pressed constantly, which effectively disables the other switches.

Hello, this is how it is set up already, and just in case, i also tried to power the FS7, but it did not change anything.

As soon as i unplug the FS7, i regain control of the MC6 pro, and as soon as i plug it back, the MC6 freezes.

FS-7 needs to be powered for it to work as a normally open footswitch. More info here: Boss

Also, very the polarity and mode switches to check that it matches that in the link above, and that the TRS cable is connected to the correct port on the FS-7.

If the MC freezes when it is connected, then it is simply because the Tip or Ring is being shorted to ground, and the MC is reading it as a switch being pressed down and is waiting for it to be released.
