APC40 mk1/iconnectMIDI4+/Octatrack OTB questions

Hi everyone!
I’m a new octatrack mk2 owner and I have some questions regarding midi control with the APC40 mk1 and iconnectMIDI4+. I would like to map my APC40 to control my OT in a more intuitive manner. I have looked around online and haven’t found any real experience with this combo. I’d like to know whether this is possible and the best way to go about mapping the controls? I don’t need suggestions for alternative MIDI controllers, as I have done plenty of research. I am only looking for info regarding the APC40 mk1 specifically.
