Hi Dennis,
found what I was refferring to in a museum haahaa, I had a 2 or 3 of them. I think it was the filter I had in mind, but not 100% sure now whether it would do the job anyway. http://www.keyboardmuseum.org/ar/a/anat/anat.html

I ended up with a midi patch bay in the end.

best wishes
rikki
