>>Speaking of being *very* useful, what is this thing exactly?<< I patch my 1V/Okt signal(s) to it. those are coming mostly from a Seqeunzer. Basically i have just one Sequenzer patched to it to the first input. With the related switch i can switch the sequenze between minus and plus. this gives me a first possibility to "play" with my groove. then i can add with the switches 1Volts and shifting the SEquenz up and down this way. In combination with other Knob and Switch tweakings this is a nice way to "play" with my grooves. since having more then one Sequenzer i sometimes patch both Sequenzers to the a-185. so i can mix them together in many Ways. hmmmm......Yes i use it as a precise mixer. You're right ;) I got this way really nice grooves. another thing is that the a-185-2 works also as a Buffer. Not unimportant when you use to patch 1V/okt signals over multiples to many destinations as i do allways do. Now ilike to have a second one or maybe two more. i thought when use it to patch FM it might be good to have the Voltage Adding very precise.
