CMC midi pulse


I have 3 CMC controllers connected. AI, TP, and QC. Whenever these controllers are connected, I constant MIDI pulse on the MIDI out. I can actually hear it if I am holding a PAD sound on my TRITON. I would really like to keep using these controllers, so is there any way to get rid of the MIDI pulse?

Thank you

Nevermind resolved. Midi pulse still happening, does not affect sound.
