Can confirm but it's not just wah, it's whatever is assigned to an external pedal. The presets or the modifier has changed so it's not honoring the values from the stored preset when I operate the pedals.
I'm seeing it with two EV-2 on pedal inputs 1 and 2 on my FC-12 attached to the FX3. The FX3 is running the 19.04 firmware, the FC-12 is on v1.12, the editor is 1.10.10. Prior to this they've worked without problems.
My volume is on External 1 in the preset. MIDI Extern control 1 is assigned to FC1 Pedal 1. The Wah is on External 2 in the preset and correspondingly MIDI Extern control 2 is assigned to FC1 Pedal 2. Bypass is set to 95% (toe down) on both. Auto Engage is set to SLOW SPD, but no position makes a difference.
Recalibrating the pedals shows the FX3 can see them and responds to pedal movement.
I have the VOL and WAH blocks assigned in a number of presets, and they'd worked fine until this update.
I'm continuing to experiment to see if I can figure out how to get them working again. The next step is a reset of the system settings. :-/

PS - I reset the MIDI/External settings. No difference after reassigning them to the FC1 pedals. I reloaded the blocks from my block library, and they immediately bypassed, where previously they had been ignoring the settings. So, currently I think the solution is to reset and reassign the pedals in MIDI/External…. I saw some related confusion during the beta, but at that point simply reloading the block fixed it in several presets. Attached is a preset that I haven't touched, which is demonstrating the problem with both the Wah and Vol blocks.
