DIY cv out module to accompany A152 question

DIY cv out module to accompany A152 question

2016-03-13 by Neal Layton

Dear all- I have a DIY question for you...

The doepfer a152 is one of my favourite doepfer modules- a classic!

What I'd like to do is build an 8 x CV OUT module to accompany it.

I'm imagining 8x (0-10v) out jacks each controlled by an individual pot.

Sat beside my a152 using 8 x patches into the a152 would turn it into a voltage controlled sequencer.

Firstly is such an idea practical? (With my simplistic electronic knowledge I was imagining resistors from power rail to drop the voltage to the 8v range in series with each pot and jack…) And secondly, if it is practical where I can find any schematics or advice to build it. I've googled but found nothing...

I should probably mention I've got good soldering skills having made many projects, but scant electronic design knowledge!

Many thanks,

Neal

Should work. Simply connect each potentiometer between GND and +12V (or use a 10V regulator 7810 if you want 10V). Important:
install a protection resistor (~1k) beteen the center terminal of each potentiometer and the corresponding CV out socket. That's
necessary as for a short time a short circuit is made when a plug is inserted into the socket. If the potentiometer is fully CW you
would establish a short curcuit between +12V (or +10V) and GND.

Dear Dieter (and all),

Many thanks for taking the time to reply to me!

Further to your advice could you (or anyone else) tell me if this circuit I have drawn will work using an LM7808 8v voltage limiter?


(I have only drawn 4x CV outs on it)

Best wishes,

Neal

PS Dieter I cannot thank you enough for your A100 Eurorack system– it has always been my dream to own my own modular synthesiser– and because of your designs, I can...! :)

Since we are talking about expansion modules for the A-152, I thought I would put a suggestion for achieving something similar with the A-154. I think a good and inexpensive expansion module for the A-154 would be a small panel with 8 jacks that a stand alone A-154 would plug into, that would provide 16 sequentially addressed gate outs controlled by the A-154. Basically a gate sequencer instead of the standard A-155. It would be nice if the module had a header to accept the ribbon from the A-154 and also have a “pass-through) header allowing the connection to more than one module to run in parallel. 

I have always loved the idea of a “modular” sequencer with all the functions of a classic sequencer broken out into separate modules that could be combined to make a custom sequencer of your own design. With the A-154 as the “brain” of the system, you could have expansion modules like this gate out module I just described, a small panel with pots for the CV generating part (that could be chained for more rows), a 16-position sequential switch module, and other modules that would connect up. This way you could design a “sequencer” with as many rows of CV out, Gate outs, Trigger outs, or whatever you wanted. It could be as big or small as you wanted. 

I started to make a system like this with my PGM-4X4 series which can be stacked as high as you have cabinet space. in programmer mode, it can address its columns using a internal, very basic, sequencer or manually or via external gates. I currently run two of them with the outputs from a A-152 but the A-154 would be a MUCH better controller since it provides clock outs too. 

I asked Dieter a long time ago about accessing the header on the A-152 and was given the pinout (Thanks Mr.D) which when buffered for protection reasons, can provide a trigger when the A-152 changes stages. This makes the A-152 a much easier module to use when using the CV stage address method. If a add-on expansion module was made for the A-152, adding this trigger out would be a BIG plus for me.

Yes, this circuit should work. But I'd reduce the value of the potentiometers a bit (e.g. 10k) to obtain a more linear control
behaviour. A 100k potentiometer with a 100k load (typical load value) has a very non-linear control scale. With a 10k pot that's
much better. Of course the best solution would be a buffer for each potentiometer output but that's probably a bit over the top.

Hello James,

thank you for the detailed annotation. If there are sufficient inquiries we could develop such an expansion unit. But I fear that
this application is a bit too special (generally the A-152 is far a way from being a good seller)

I would not wish to take any sales away from Dieter because his stuff is fabulous, but there are of course many others out there following in his footsteps and making modules. For a series of fully "modularised" sequencer modules (!) take a look at the 'S' series from www.ladik.eu which is a system with masses of potential to make sequencer configurations in many different ways.

Re: [Doepfer_a100] DIY cv out module to accompany A152 question

Dieter - 
The A-152 is a bit of a specialty module for sure. To many the features are very obscure. I imagine that most people mainly use the Digital outs and not many use the other columns very much. For me that is the case anyway. The Voltage addressable digital outs is a vert cool feature and the main one I use on it. It is not a very expensive module though so other than space reasons, it is a great module to have.

Here is a simple addition that would do basically what I originally talked about with a A-154. This would add the voltage addressed digital outs to a A-154. How hard would it be to create a cable that would connect a A-154 to two A-161 (or maybe two A-149-2) modules? With an adaptor cable like that, An A-154 and two A-161’s would make a great little 16 step gate unit.

I'll see if that's possible. But at the moment I'm snowed under with work because I have to prepare for the Superbooth in Berlin.
The prototypes of a few new modules have to be finished (e.g. a new high end VCO, a micro VCO with 4HP only and a performance
mixer).

2016-03-18 by Bakis Sirros

New High-End VCO...wow! will it be triangle core? 
i guess it will include linear and exp FM, TZ FM of course. 
will it have an on-board wave folder ? will it have an on-board modulation (2nd) vco ?

A-111-2:

triangle core: yes
frequency range: ~ 14-15 octaves
waveforms: tri, saw, pulse, sine
linear FM: yes (manual control, down to ~zero + CV input with attenuator)
exponential FM: yes (manual control + CV input with attenuator)
PWM: yes (manual control + CV input with attenuator)
hard sync: yes
soft sync: yes
TZ FM: no (this will follow in another new VCO A-111-4?, not yet included in the A-111-2 and a more expensive)
wave folder: no
second VCO: no (from my point of view another VCO can to the same job)

A-111-3:

slim version of the A-111-2, 4HP only, less controls and less in/outputs

Details will follow soon on our website
