Midi input issue

I have a modal 02 synth thats works fine with other gear b and other gear works fine into the squarp but I just cannot get the 02 to send midi notes into the squarp … why could this be …ive done all the trouble shooting …there is some kind of setting im missing

weird thing …if I go through my mpc the squarp receives midi from modal …??? im stumped …

Could it be a channel thing with the MPC routing the input to a different MIDI channel then passing it through?

oh, that modal synth looks awesome!
