CS80 indeed. There is an almost identical patch for the Arturia CS-80v if interested:

The CS80 was decades ahead of it's time. I love playing with CS-80v, but I need a keyboard with polyphonic aftertouch to do it justice, and the Ensoniq models are now way too pricey. Wish I'd bought one 10 years ago when they were unpopular, available, weird and cheap.
Regarding the Oberheim brass... it's incredible :) , I probably wanted it to be the OB.
