The Axe 1 would ignore 5% movement in either direction before allowing an external controller to take over, whether block state via auto-engage or any parameter using PC RST. The Axe II (FW 10.00) only does this for PC RST. This causes a pedal parked in the "on" zone to randomly autoengage blocks after switching to a preset. This happens invariably with the Axe pedal port (usually within 2-5 seconds, tried with 2 different pedals & cables) and any change in value via CC.
