Dieter,

i see your point, but in this particular case a common attenuator, 
voltage controlled if possible, acting on all outputs simultaneously 
would be great; there are a lot of possible applications i can imagine 
where one would want to have identical modulation intensities at all 
destinations, just phase-shifted in relation to each other. making all 
those modulation amounts voltage controlled at the destinations by 
inserting VCA's would be a LOT of work in comparison to just modulating 
overall output level on the source.

just my 2 cents ;-)

Has anyone here MOTM'ified a doepfer? Does anyone know of any resources 
to do this? ie make the doepfer safe to run on 15 volts and any front 
panel express panel designs.....

Thanks,
Jim

We have added some information about the planned/discussed modules to our
website:

A-143-9 Voltage Controlled Quadrature LFO: www.doepfer.de/a1439.htm
A-138x Mix Expander: www.doepfer.de/a138x.htm
A-138c Crossfader: www.doepfer.de/a138d.htm

Wouaaahh!!!!

I dont get it all sometimes with complex module technical things... but that 143/9 seems 
really interresting...

what about the 143-4... the synced VCLFO one actually?

also for the mixer expander, once both of them soldered... the ONLY output is from the 
original A138... am I correct?



BUT... its just I'm waiting for my order to arrive at MESI in Paris for more than a month 
now... A188-1 especially... THIS IS TOO LONG... OR MAYBE I'm really not patient enough...


WHY DOES IT TAKE SO LONG TO GET THE THING COMING JUST GERMANY TO FRANCE????

You should try getting this stuff to Australia.

Assuming you can get Australian distributors who don't appear to be
particularly interested in making any sales to give you a quote (I've
been waiting for prices on a number of modules and a 6 unit frame for
6 weeks despite constantly hounding them on the phone) it takes a
couple of months for the goods to arrive once you place the order. 

Cheers,
Adam-V

Yes but... for example if I look at Analog Haven  the US distributor... iT says for most 
modules/products... "ships within 24 hours"...

So I understand distribution is really really different on account of the distributor of each 
country... I guess they just stock the modules in Analog Haven otherwise I dont 
understand how they do... but actually can they stock every single module... ????

We are still working on this module. It' more complicated than we believed.
The first processor we used was to slow after all though it's an LFO only.
The problems are the continous waveforms (saw, triangle) as you need much
more processor power than expected. E.g. if you want to generate a 100Hz
sawtooth with 256 steps of resolution you need a update rate of about 25 kHz
from the processor - not only for one but for all waveform outputs. If only
rectangles are generated it would be no problem. But generating sawtooth and
triangle is not as simple as we assumed.

You have to ask MESI. I'm not dealing with the orders and shipping. As far
as I know we have all products in stock at the moment. It's probably because
MESI (and other representatives too) normally collect orders and order only
about once a month to keep the shipping charges as low as possible.

Please contact our sales department (sales@doepfer.de). Maybe we can sell
directly to you. I don't know the current state of our Australian

Hello Mr. Doepfer,

If the design allows it, I think a reset on the quad-lfo would be very 
nice.

this looks like a nice addition to the A-100

Maybe this has already been discussed, but wouldn't a cv input to sweep crossfading be a 
big plus?

Hello 


In fact its all arrived YESTERDAY

I'm totally excited... A106-1 and A188-1 is JUST SO GREEEEEAAAAAAAATTTTTTTTT... its 
gonna take weeks of study and all to just.... learn working with these....

Hmm, why do you try to generate it completely with digital means? I'd 
create a rough waveform and send it through a VC-slewlimiter, where the 
slew rate is depending on the frequency of the intended waveform. The CV 
for the slewlimiter would be created by the uP itself. A D/A-converter, 
a Demux, and a S&H is assumingly already on board.

In fact: it has been discussed ;-) And the answer is: the A134 is what 
you are looking for. The forthcoming crossfader module is not intended 
for a different approach. See: Message #10213

Good idea. I'll see if it's a practicable solution. It would require a
voltage controlled current source to charge/discharge the capacitor. As long
as the frequency is stable it should work. But if the frequency (CV resp.)
changes it may take some cycles until the waveform output is correct. We
will see if it works.

This module looks quite nice to me, but IMHO, one ore more built-in 
(passive) attentuator(s) would make it even more versatile.

Either a single attn. for all four outputs simultaneously or four 
attns, one for each output.

It might add some extra width to the module, but the added benefit 
seems worth it to me.

Best regards,
Joost

Thanks for your response Dieter. Last time I checked you would not
deal directly with anyone in Australia due to an agreement with the
distributors. This is, of course, the right thing to do albeit much to
my (and I dare say others) utter frustration. I will check again with
your with your sales department though.

The basic concept of the A-100 is that the attenuators are located at the CV
inputs. Only modules that may be used normally as the last module in an
audio chain (e.g. mixers, VCAs) are equipped with attenuators at the
outputs.

Hello Denis,

of course it would be possible to add four VCAs. But this would at least double the price of the module. I think one or two dual VCAs A-132 would be a good solution for this application. But of course we could add the VCAs to the module if the user prefer this solution. How about a poll ? At the current state of the development it would still be possible to add the VCA feature. 

Best wishes
Dieter

hello dieter,
ok, poll is on the way...

hello dieter,

from my point of view it would make sense to add a quad vca
which controls the amplitude of all four lfo's simultaneously
with only one voltage and/or knob. this would not add as much
to the price of the module as fully separate vca's. 

if someone would need separate control of the lfo's, then
external vca's should be a good solution (2x a132 or similar).
it's a modular system and four independent vca's would
be a waste of resources if you could use them for the
lfo amplitudes only.

best wishes

right... exactly!

hi

> of course it would be possible to add four VCAs. 
I thought the LFO is computed in the uP (or do I mismatch with the 
143-4?). If I am right: Why dont't we use a CV-in for the waveform 
level, A/D-convert it, and include the level in the waveform calculation?

The A-143-9 is an 100% analog circuit (a bit like a VCF in self-resonance
with LP = sine and BP = cosine). Only the A-143-4 has a microcontroller with
DACs.

yeah man, that is really taking the back to analogue thing too far!

lol.....actually 1970 i wasn't around to do *anything* (including 
writing not-yet-invented emails)....i guess i should put a new buffer 
battery in my laptop :-)

i fully agree to the notion of one quad vca with common voltage control 
for all outputs, that's what i meant in the first place....as for 
*quadrature* applications this is all you'd really need, just without 
the hassle of 4 extra VCA modules.  for "synchronous, out-of-phase 
modulation" applications aka *individually different* amplitudes you 
can use seperate VCA's with the benefit of increased flexibility.

We discussed the additional VCA option for the A-143-9 and have another suggestion:

How about a separate quad VCA module with one common control (manual + ext. CV) for all VCAs. This module could be used even for other applications than only for the sine/cosine outputs of the A-143-9. E.g. for the other four-fold modulation modules of the A-143-x series like the quad AD, quad ADSR or quad LFO. A separate quad VCA module would not be very much more expensive than four VCAs integrated into the A-143-9 (4 additional sockets plus a separate front panel). After all the quad VCA section of the A-143-9 would be also a separate pc board containing the four VCAs. If we add four input sockets and make a separate front panel we would have a separate quad VCA module which is from my point of view more flexible than four VCAs only for the A-143-9.

Tell me what you think.

Best wishes
Dieter Doepfer

Tops idea.  Eurorack is shy a quad vca something fierce.  Please do  
the blacet thing and break off one of them for use alone, if possible!

hello Dieter,
yes, i think that a separate quad vca module would be
best!

Bakis.

IMHO, this would be most interesting if this Q-VCA could also be 
connected to the A-149-9 behind the front pannels with a flat-cable 
(like A-149-1/2 and A-160/1), omitting the need for 4 extra patch 
cables.

It would offer the combined benefits of efficient prepatching 
functionality as well as modular versatility. Without connecting 
this "under water" flat cable, this VCA could then be used for many 
other modules beside the A-143-9.

Is this perhaps a feasible idea ?

Best regards,
Joost

It should be no problem to add this feature to both the A-143-9 QLFO and the
Quad VCA.

Happy holidays to all of you
Dieter Doepfer

For all users who are interested in low cost DIY cases/supplies/bus for
A-100 we will offer a kit probably from February 2007. Details on our
website on the news page.
