If the green circle below represents the original MuMidi HubLink, we might visualise the its internal routing as a bi-directional link between its two USB sockets.

[This might show the USB ports as comprising separate "In" and "Out" nodes, but we know that both "In" and "Out" are contained within the same connector. "USB1" indicates the upper port on the MuMidi HubMidi. "USB2" indicates the lower port on the MuMidi HubMidi. ]

MuMidi HubMidi adds a serial MIDI In port and a serial MIDI Out port and internally provides communication with one of the USB ports.

If the blue circle represents MuMidi HubMidi, we might visualise this as below.

[In this case the serial MIDI "In" and "Out" ports each represent a single MIDI DIN connector.]

In addition to providing bidirectional communication between the two USB Devices, MuMidi HubMidi also provides  bidirectional communication between one USB Device and the serial MIDI ports.

This creates what we call a "Common USB" routing.

For Customers who require more esoteric routing options (e.g. "Common MIDI" or "One-way"),  we can also supply a "special order" variant, "HubMidi-S", that includes a switch to select between various routing options.

Typical MuMidi HubLink Applications
Thru

One potential use for MuMidi HubMidi is to connect one controller to two modules. For example, one USB-MIDI keyboard connected to USB1 might be used (perhaps with a keysplit on MIDI different channels) to control two separate synthesizers, one connected to USB2, one connected to serial MIDI Out. All MIDI messages arriving from the keyboard are sent by the MuMidi HubMidi to both Synthesizers.

Merge

Another use for MuMidi HubMidi might be to connect two controllers to one module. For example, with a USB-MIDI keyboard connected to USB2 and a MIDI drum sequencer connected the MIDI In, a multi-timbral module connected to USB1 would play both rhythm and melody parts. MIDI messages from both controllers would be routed to the module.

MIDI Merge is a technically challenging task (which is why MuMidi HubMidi has been subjected to such rigorous testing), but all this happens automatically within the MuMidi HubMidi.

HubLink routing

With both serial MIDI cables disconnected, MuMidi HubMidi behaves like MuMidi HubLink.

USB-MIDI Host

With USB2 disconnected, MuMIDI HubMidi behaves like a USB-MIDI Host.
