Doepfer

hi to all,
please tell me what you think...which vco do you prefer?
i personally like the sound of the a111 more than the a110(i think 
the a111 has a more warm,mellow sound and the a110 has a more 
agressive,sharp,cutting sound...).
but,after all ,i like to have both kinds of sound in my doepfer 
system...
i'm waiting for your opinions!

The A-111 is much more stabile, has a much better linearity over the
whole frequency range. Additionally it has hard- and(!) soft-sync and
linear frequency modulation. Soundwise I think the A111 bites more. The
A-110 can have a little highe outputlevel, so you might mix up the
distortion in the next module with "brighter" sound.

Hi,

I´ve just compared both VCOs and think the 110 sounds fatter and indeed much
sharper than the 111; especially when you mix one 111 & one 110 the sound is
not as thick as when mixing two 110s. My opinion. Might be the effect of the
lesser stability of the 110s.
Both VCO´s Hard Sync is nice, but totally different.

Personally, I don´t have a favorite. Both sound very good. The 110´s price
is unbeatable. The 111 *is* expensive, but the linear FM feature is worth
the cash.


Curiosities:
-The 110´s output  is louder than the 111´s.

- The front panel on the A-111 shows a SAW waveform ( the sawtooth starts at
the top and goes down to the bottom then resets at the top),  but in reality
the module generates a RAMP waveform ( ramp goes up to the peak, then resets
at the bottom and "ramps" up.).  Why is that?

- When I plug my oscilloscope into the 111´s PULSE out, the offset seems
wrong to me. It looks something like this (i hope you all can see that):
  ___       ___
_|__ |__  |__ | __  ___
        |      |     |      |
        |      |     |      |
        |___|     |___|

Within ten to twelve seconds it "glides up" to a normal offset:

  ___       ___
  |     |      |      |
_|__ |___|___|__  ___
        |      |      |     |
        |___|      |__ |

the whole effect is inaudible, but interesting nevertheless. Is it an error
in the CEM 3340 or in my ´scope (I don´t think so, because it works OK with
my 110s)?

Hi Paul

Thats why you think, the 110 sounds fatter. Turn down the level of the
110's signal (measuring with your scope) and compare then.

There is no difference between the "Ramp" or "Saw". A simple inverter
changes inbetween. Forget it.

In general Doepfer modules have not DC-offsetted outputs. Instead the
inputs of the following modules have capacitors for offsetting from the
DC.


> Within ten to twelve seconds it "glides up" to a normal offset:
This is an effect of your scope.
