>>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.

H.
