Caduceus

The other five modes are for Thru and Merge. The PDF I included is the only mode for a USB output.

I have been using a MidiBox for some time and it appeared to stop working so I bought a new one. It doesn't really have a name, just USB MIDI BOX 4i4o + Merge 2i4o. I have four keyboards (one is a pedalboard). The MidiBox only works on Channel One. Each of the keyboards works okay if it is plugged into Channel One so there is obviously nothing wrong with the keyboards. Is there some setting somewhere that I may have missed or changed inadvertently? Help would be appreciated. I have attached a PDF of the manual that came with the MidiBox. MidiBox.pdf
