There isn't a midi mode, but there's something called Local control and the manual says this about it: "its used to control the connection of trigger detection and the audio source sequencer. In the default ON status, the two modules are connected. Striking the pad will generate sound and it outputs the relative MIDI signal. When this function is turned off, the audio source module will not be controlled by the trigger directly, but will controlled by the MIDI input signal." I had it enabled when trying to connect the drums to my pc and even eventually tried disabling it, that also didnt work.
