I need three MIDI switches that have one in and two outs with a switch that can choose the destination of either output. So if I had a master keyboard outputting into the MIDI switch in then I could switch between the two outputs. My searching on the net found Phil Rees and Kenton MIDI switches. They are both discontinued products. This makes me think the need for MIDI switches has changed over the years. I need three of them. Roman Pirie.
