I’m not sure if this is a bug, or intended to work this way, but I have had this issue on my HX Effects through multiple devices, resets and upgrades, and it is an issue on all of them.
Currently using HX Effects on 3.5
I have a mission spring loaded effects pedal that is inactive on the snapshots, but is set to activate the effect when the pedal is moved and then deactivates once it returns back to normal (0%) position.
If I engage the pedal for a wha effect, then release and quickly change to a different snapshot, the wah pedal is active on the next snapshot when it should not be, and does not inactivate even though the pedal is back in its (0%) position.
This basically activates the muffled wah effect on my snapshots where it the effect should not be engaged and there is not a good way to disengage it, because the pedal is already at its (0%) position.
