Sorry, maybe I was doing something wrong all the time...
So what you are saying is you place the cursor in some other column than SETUP, press TEST, construct another curve, press TEST again and the original curve is still there?
Or do you EXIT, SAVE and reenter every time you shift the cursor to another column?
So if I understand you correcrly, you CAN end up with 6 different curves?
What is the purpose of LOCK, then?

Well, yesterday evening I played around with the Behringer again, problem is there's no level control, and for some reason it doesn't sound so "clean" as the SMS-1.
Of course I can haul my now extinct Outlaw analog bass management from the attic, but I don't really want more cabling with extra hum and noise...
Another good thing about the SMS-1 was you can have several volume settings- I had made 6 buttons on my Pronto remote plus mute which worked very well.
So I may reuse the SMS-1 and "play it by ear"...
