MRCC MIDI input 6 use

[QuattroP]

Hi,

Is anyone using the 6th MIDI input on the MRCC? I got my hands on TRS to DIN MIDI cable type A so I tried using the 6th input for the first time. I tried with some synths, connecting the DIN end to them and with the TRS end going into the 6th input. Whatever I do I'm not getting any input in.

What am I doing wrong?

Thanks!
