Can't Turn Off Reverb (All Sounds)?

[charmac2nd]

Hi there,

I went to use my Nord Electro 5D this morning and noticed that every sound was drenched in reverb that I can't seem to turn off. I thought it was my DAW at first but even running straight into a speaker, every sound still has reverb even though the effects options are all turned off. Even turning them on and turning it down to 0 does nothing.

Does anyone know how to fix this? I tried standard IT solutions (turning it off and on again, etc) to no avail. My assumption for how it got this way is my cat - he likes to walk on things he shouldn't and in the past has accidentally programmed some weird sounds as a result.
