This pertains to both Analog MKII machines
Since the A4 has multiple destinations per LFO, it benefits from mapping the ‘Fade’ param(s) to a macro to engage/ disengage depths (defaulting to +63 and setting a macro knob to modulate by -63 or vice versa).
This works swimmingly until you go to mute/ unmute said macro (via func + qperf) as the Fade param sticks to the muted state and requires an additional turn of the macro to re-engage the LFO(s) in question.
