I seem to remember this happening with another device of mine (maybe the H9?). With the PC & CC messages being received serially – a few milliseconds apart – perhaps the Program load is ‘swallowing’ the CC value.
I’ll try this later on, inserting a fixed delay time between messages. Straightforward in a Morningstar, but I didn’t find a similar option in the Boss. One possible workaround: Trigger the “internal pedal” with the ES8 patch, and delay it with the adjustable ‘Tim’ parameter. As a diagnostic, if anything.
