Blooper control with my mc6 via TRS


I’m trying to link my blooper to my mc6.

I’ve tried the omniports in various ways - MIDI out (standard) and both ring and tip settings.

The blooper seems to react to the mc6 being connected (the lights flash and it behaves oddly).

I’ve tried various TRS cables, I’ve tried disconnecting the tip of a cable.

Has anyone got this working? I did and then it stopped again so I’m sure it’s user error.

Any thoughts, tips, advice much appreciated!

Happy Christmas
