After having mail contact with Chris from Doepfer who offerd excellent service to take care of a new processor I couldn't resist also order a new A160-5 at Thomann.
Once installed in my system it worked like a charm, no latency issues or whatsoever.
Thank you again Chris for your help with this and with sending me the long
awaited update software for my A157's.
