MPC Sample with melodics

Has anyone used it with Melodics? I tried it on macOS, and it works. The only thing you need to do is configure the MIDI settings on the MPC Sample: press SHIFT + Pad 8 to open the MIDI configuration, then set the MIDI port to USB.
It doesn't work with the iPad or iPhone, though. Hey, developers, could you please look into this issue?

Worked fine on the app on windows, except for some reason I couldn't claim my free lessons. Just kept erroring. Will try again.
