No midi output

Hello.

My mpc500 work well on its own, but doesn't send any midi message.

I've checked with midiox, loaded a defaut (empty) file when turning on mpc, nothing appear...
When tested with same cable, same input port (motu ultralite mk3) and different gear (xboard25) I can see there is midi message received.

Can't find an option, seems like something broken? :/ I hope no.

Please share if you have an idea.

Thanks,
Christophe.

Ok I have the answer: I had to go to track parameters and select a midi channel (per track), none is selected by default.
Thanks circus prod
