(as I am trying a new setup the problem could be on my side…
so… if anyone can confirm this behavior …)
it seems that when we are on the 2ND + TRACK menu
the Pyramid correctly receives the Program Change messages from midi input (and it updates the information on the 2ND + TRACK screen)
by cons, it does not receive the LSB / MSB messages…
(I deactivated the filters for CCs in the settings)
is it a bug or I have to check something else in my setup?
