Organelle is a USB host (like your computer!) , that is why it has a Type A USB port… and not a Type B.
generally you cannot connect to usb hosts together, its usb host to usb device.
so if you want to connect to a computer, you either need to go via usb to MIDI DIN, then DIN to usb.
however, there are a couple of gadgets that can do host to host, like this one.

the other popular one is iConnectMidi , but that’s quite expensive, just for this.
