I understand what you say, and would usually agree in every word, but this time Arwin gave me the impression of wanting something like what I suggested, he is playing carefully, and does everything here so this may be reversible. I see no risk of harming this nice instrument working this way. I really hope Arwin reads what you say, and considers it well. I will not make more suggestions in this thread until someone asks for it. I have learned lots from this forum, and I hope I may give something back from time to time. My best fettle (so far) was to make connections between my SXS PBX and IP telephony. It is still not perfect, but it have got more options then it had as new in the 1940'ies. (and I have not soldered or desoldered a single wire in that PBX)
