Hello Paul, I do not think that I will ever have any problems with 1volt/oct stuff, as the modules that mostly output more than 12 volts should be the clock/gate trigger sources of the blacet/metalbox modules range. So, I cannot see any problem here with the 1volt/oct tracking... The cv sources modules will most likely not output more than +/-12volts, I guess...so there is no need for passing these signals thru the attenuators. So, the simple a180 modified multi/attenuator idea of Dieter Doepfer is great, for me at least. Many thanks, Best regards, :-) Bakis.

I'd add input protection to all inputs that needed it.. But..... if somebody has a mix of units, AND doesn't want to modify them, then one is going to have to put something in front of the vulnerable inputs. And one thing I *wouldn't* like to have to use is a simple resistive divider (if that is what Doepfer is going to provide the original poster) because, there goes your 1 volt per octave. One good thing about this discussion is that people are now somewhat more informed of the dangers. paul perry Melbourne Australia ----- Original Message ----- From: "Bill Fox" > Limiting the voltage *at the ouput* isn't how I would do it.
