Hi Nick, thanks for the detail. I guess (in my view) the point of the A/B bypass is for live use or improvisation – to get more out of the unit – ie use as 2 independent FX units. In this regard for it to work reliably one needs a defined on/off state for each block controllable via a hands free controller that can be received by the Eclipse from a Prog Change (from the Ground Control) that includes CC information. Most other units work in this way – my POD Pro is excellent in this regard. My Ground Control does not have the ability to program sys ex. Are you suggesting in your message this will be fixed in a future OS?
