I have a MOXF8 and a Hammond SK1 that I use as my stage rig. I want to use the MOXF as a lower organ register on some songs but not most. So I would like to be able to turn on and off the MIDI out so that when I am using the MOXF for something other than organ (using the SK1 as the engine) I do not get the organ playing through. A good use case would be on song 1 I need the lower organ register and will not be using any internal MOXF voices, easy enough just dial sown the volume on the MOXF and I get a beautiful dual register organ and no MOXF voices. Scenario 2 is where I have problems, when I have the midi cable attached and I need to use both keyboards in their native environment. In this case I may have the MOXF set to Concert Piano for example and the SK1 is cranking, I get organ from the MOXF through the midi to the SK1, this is not good as the parts are different. How do I use the foot switch to toggle between these scenarios without pulling and replacing the midi cable?

Thanks
Greg
