how to start a sequencing Doepfer case system? |
|
|
Hello to everyone,
This Christmas i receive a Doepfer 6u case from my wife, and now i want to start buylding a modular synth in eurorack format.
Cause i have the Doepfer Dark Energy, i want to start my system oriented to sequencing, to make sequences with the DE.
I thought about sarting with the A-155 and the A-156 modules, and later i will buy a A-190-1 for the system receive midi clock from my software sequencer.
About the clock divider i want to know if its a necessary module for this initial and the later midi configuration, with the A-190-1 (cv/midi/sync module)
If you have a better idea about a sequencer oriented doepfer system, please say something
Cheers

Hi Pedro,
Well I'm not an expert but I think you are going to need some clock generator of some type, a LFO would do or maybe a A-154.
Or you could save the rack space and get a Dark Time
Cheers

Im going to use the Dark Energy LFO1 output to give clock!

Lets see...
I you use your only LFO for clock then you don't have an LFO for modulation. You could clock with the A-191-1 though I believe you would then have to send MIDI clock to use the sequence.
You don't have to get a MIDI to CV converter as a module though there is an advantage to have it inside your system. To some outside the case has advantages too.
The A-156 isn't essential but it makes the use of an analog sequencer much easier and to many people much faster.
An A-150 is not essential but lets you use the A-155/A-154 in 16 step mode rather than 8 step mode |

Any Progress? |

Hi Sonic...
Did you make any progress with this?
From my reading on the Doepfer site, A-150 plus A-155, and A-154 does not give you 16 steps, but you need to add a second A-155. Of course, I could be mistaken on that At that point, or even with only one A-155, A-150, A-154, I would think DarkTime would be better - bit pricier than that combo, but saves a ton of rack space and gives you MIDI I/O also, with clock sync to or from other MIDI.
I do not have this equipment, but have been reading up recently as I am interested in sequencer options right now.

One A-155 and a switch will do 16 steps, you have 2 rows of 8 steps going out on 2 CV outs, you fire the switch on one of the 8 steps and you've switched rows until you file the switch again. What you can't do is something trickier like have one row alter the clock speed or use a second CV in parallel to do something else at the same time like open the filter some amount on some notes. You can do that with 8 but not 16 steps until you get a second A-155.
Dark Time is a ready to go old school sequencing system with nice extras like MIDI clock to tempo, quantitizer, stop/skip/jump switches. I don't have one so I don't know if it's easier to use but it probably looks like the popular uses are easy to use
That said the A-100 series modules will do a pile of more advanced things due to having a lot more CV inputs and outputs. There are a lot of patchable options especially once you add the A-154 controller. Even though the A-100 series modules are admittedly pretty space filling in a rack, what struck me is the patching options goe way beyond many other people's step sequencers |

Hi ndkent
Thanks for the added info. So many choices, I was mostly taken by the stadalone enclosure and MIDI I/O of the DT. However, I have seen videos of people creating great sequences just with things like clock dividers, so maybe just adding clock and switch modules is actually a more flexible way to go. I have some of the Symple SEQkits that I am messing with now, trying to see if they can do what I want, and building simple dividers with CMOS.

One would generally not make a good melodic sequence with *just* clock dividers. Generally you have a mixer that deals with CV. You could take an A-160/161 combo and run each step to a mixer input that passes DC. That means instead of a uniform +5v or whatever the divider puts out you get a pulse of CV you could use for pitch, especially with that combo, since each step holds, so it's not a tiny short pulse that may bot get far. Anyway that's a melodic result.
For a rhythmic result many synthesists divide with different intervals and perhaps logic applied and then take the different triggers and make different sounds for each trigger out. Something like a 4ms RCD puts out lots of different divisions at the same time |

Thanks for elaborating. Do you know any other good tricks for alternative sequencers?

Hi, the switch that you talk to turn the A 155 in a 16 steps sequencer its like a switch module like the A 150 or A 151....Can you explain me better how to do it....Have you ever tryied?
Thanks a lot
