Actually the phenomenon disappeared today, no particular action carried out.

Out of curiosity - what is InsA's effect name?

Be aware that the dry/wet or other parameters important to "hearing" this effect may be under control of superknob, assignable knobs, assignable switches, expression pedals, foot pedal, etc. Inadvertently twisting a knob or pushing a button may have "dialed back" the effect making it difficult to hear. Recalling the original Performance would reset all of that and restore the controllers in a way that perhaps doesn't minimize the insertion effect's ... effect.

Usually when it seems the carpet is being pulled out from under you by a "ghost in the machine" - the cause is actually programming and the keyboard is responding correctly to what it has been programmed to do. The biggest category of this "ghost" are the control assigns under "Mod/Control" -> "Control Assign". You can look for "InsA" in all of the destinations (set the filter to "All" and page through all pages looking for InsA). If you find InsA has some parameter modulated by a controller, then look at the Source for this destination (touch the InsA destination and look at the "Source" field) to find out which controller would be modulating this parameter. Then you could purposefully move/push the given controller to see if you can replicate the problem. And if this were something you never want to happen to "protect" this from happening then you could remove the assignment and adjust the destination parameter (the "real" value in the InsA parameter menu) accordingly if needed. It's (unscientifically) a 50% 50% if any "touch up" after deletion would be needed. If the source is an MS Lane or Envelope then these cannot be directly "pushed" and "turned". You could, however, turn off Motion Seq altogether which "resets" it. And Envelopes seem rare (so I'll just ignore having to worry about that for now).

Another item that may attenuate the effect's "detectability" is some form of modulator within the effect itself. Some effects have modulators/side-chain and I suppose having these pegged a certain way could diminish the "detectability" of the effect.

I forget exact details, but another thing to watch out for is Left vs Right interplay between Elements and Stereo Insert Effects.

Example, an Element can be hard panned Left, into the Dry "Left" Channel of the Effect... so you never hear the "Wet".

As I say, I forget exact mechanics, just be aware.

Hello,
Thanks for replying.
Effect is Tempo Cross Delay/Dotted 1/8 Echo.

Thanks for those reminder 😉
