Doepfer

The following Doepfer_a100 poll is now closed.  Here are the 
final results: 


POLL QUESTION: Which of the followinmg versions of the A189-1 VC Bit Modifier would you prefer Doepfer to manufacture?
*Version 1: Leave it as it is (price ~ Euro 70, release date ~ April 2008, 8 HP
width).
*Version 2: Replace the mode selection via rotary switch by voltage control, i.e.
manual control + CV input with attenuator or polarizer (price ~ Euro 80-90,
release date ~ May 2008, ~ 14 HP width).
*Version 3: Add also a switch to select between voltage control of the sample rate
and external clock, i.e. additional switch and socket (price ~ Euro 90-100,
release date ~ May/June 2008, ~ 14 HP width).
*Version 4: Add also a (digital) VCA at the signal input, i.e. additional manual
control + CV input with attenuator or polarizer (price ~ Euro 100-120,
release date ~ June 2008, ~ 14 HP width), it is not sure that this last
feature can be realized, we still have to test if the microcontroller is
fast enough for this function (additional multiplication).

No reason to feel sorry every now and then the designer knows it better.

Dear members,

thank you for the poll results. For the A-189-1 that's what I expected. For
the A-137-2 I'm a bit surpised that only 8% vote for a manual phase shift
control. From my point of view this is a very important function. Without
this additional controls only symmetrical signals (like LFOs) can be used
meaningful to control the phase shift. With an ADSR or another unipolar
(only positive) CV only 50% of the phase shift can be covered. Maybe I will
override the poll results in this regard. Sorry :-(

Even for the A-189-1 we think about a solution that would cover the other
options too. E.g. one of the 16 positions of the rotary switch will address
the voltage controlled mode selection and we will add a terminal on the pc
board that can be used to connect an external CV (e.g. the output of a mixer
or polarizing mixer).

Thank you
Dieter Doepfer

Please override the poll on the A-137-2, I (and I presume more people)
didn't understand it.

i agree with Dieter!
that's what i tought too about the a137-2!
best regards,
Bakis.

Hi I wish to use the 154 + 155 sequencer to do

1: Sequence a Yamaha CS-30 by CV and gate----do I need another  
Doepfer module that converts the signal to Yamaha format?
2: Sync to a Roland System 100 104 sequencer as the slave via clock  
in----do I need another Doepfer module that converts the signal to  
Roland clock in format?
3; Sync to Pro Tools or Logic ?????? Do I need to use a Kenton Pro  
Solo or 190 module and sigh use midi clock??? surely there must be a  
better way than Midi clock which freaks me out

thanks Dave

Dear Mr Doepfer,

What about normalled cv inputs and polarizers instead of attenuators ?

The "4 HP expansion module with 8 sockets" is also attractive.

I'm not interested in a manual phase shift control because I would
like to control the A1372 with an A1431.

Finally, I would like to say that I love affordable 8HP Doepfer
modules. They leave space and money for your other great modules (A103
, A107, A1112, A143x, A155 ... too numerous to mention).

Best,

Pierre,

Very cool

cheers

Sells new for $699. I'll sell for $475 shipped to continental U.S. I'll
throw in the necessary a-100 AD5 5v adapter, if you need it.

This one has the adapter for the Doepfer case.

Polarizers are a good idea. But I don't know what you mean with "normalled
cv inputs". Controlling all CV inputs with the same signal does not make
much sense for this module.

Without the offset control you will not be able to cover the full phase
shift range with a unipolar signal (like the A-143-1). With a bipolar signal
(e.g. A-143-3) the full range is covered as with zero CV the phase shift is
in the center position.

Dear Dieter,

I believe it would be possible to obtain different shifted sawtooth
with a single CV signal thru different scales. Because the resulting
(polarized/scaled) comparison levels would be different.

NB1 : I do not  know what "normalled" mean, but I read it several times
on the doepfer home page : A1011 "The filter inputs are normalled";
A1432 "All Gate inputs are normalled from top to bottom"

NB2 : "For manual shifting the two upper inputs are normalled to +5V
and -5V" : this is also an interesting feature. I trust you to choose
the most user friendly and musical one. But I believe I won't be able
not to plug something into those CV inputs.

Best,

Pierre
