Hi folks,
I just bought a brand new Doepfer A100 basic system to dive into modular world. I want to pair it with my Elektron Analog 4 MK2 and Octatrack. How would I hook up the Doepfer A100 to the Elektron and my studio monitors? Sorry to ask a dumb question but modular is new to me.
Do you want to sequence the modular from the A4mk2 cv track while being able to capture samples/apply fx with the Octatrack?
yes that would be ideal! Make use of both Elektrons and have the fun of the new Doepfer A100 modular system and throw in my Make Noise 0-coast for good measure.
Ok. Do you have a mixer, audio interface or something like that or is it just OT/A4/0-Coast/A100 and monitors?
I’ve heard several times that you can go directly from ‘modular level’ into A4, not sure about OT, but you can try. Turn down amp volume and if needed track level on OT.
Ofc you can always turn down the level on your modular with a simple vca before you hit OTs inputs.
OT should be master and A4 synced to OT (so that when you press play on OT, you want the A4 to also play and you want the A4 to follow all pattern changes from the OT (so both basically always play the same patterns)?
Or do you have that part already set up and the question is only about how to connect modular?
A4 does take modular levels without any problems.
Many also go directly into OT, seems to work, but not sure they take it without any harm…
I would go from the modular into the A4 inputs. Then A4 into OT, and from the OT into studio monitors.
This way you can sample A4 and modular with the OT, and mix down your track there if wanted. You can apply the nice delay and reverb of the A4 to the modular.
i would use the A4 cv outputs to sequence and modulate the modular.
I would use the OT as master midi clock, sync the A4 via midi, and clock the modular via cv from the A4 if needed
What @Unifono said!
Plus you can even use the modular incoming sound as a source in A4. In such setup, I use the audio track as CV + gate source signal, this way you trigger and treat the modular signal in the same A4 track.
Go slowly, ie first only with 0-coast and once the setup is working good for you, that you have a smooth enough workflow, put your whole system in the loop!
thanks, I will try it out once my Doepfer A100 system arrives later this week. Should be tons of fun.
You can already practice with 0-Coast, even if it’s only to check that this setup is what you’re looking for.
Proceed one step at a time 
I have that working for some time now. My new modular gear arrives this week and will be fun to use the A4 as clock and sequencer to the Doepfer and other modules. I want to also send clock to a eurorack modular envelope generator/sequencer so will be good to know how to do that as well.
A nice thing with A4 is the complexity of envelopes and LFOs. As you can use them to shape your CV signal, make sure you don’t output only simple clocks and gates
Can you send both a clock and envelope from the A4 to different Eurorack modules and if so how exactly would that work? Being new to modular is thinking how to accomplish that. Stupid me bought an extra envelope module called Malekko Quad Envelope Generator that requires a clock to sequence the various EG settings. It would be cool to send clock to that module from the A4 and then use the A4 to trigger the modular VCO over CV outs.
A4 can output 4 different signals at a time.
Clock is meant to synchronize periodic signals (sequences, synchronized LFOs…)
To trig an envelope, you’ll most likely send a gate signal (goes from 0 to 1 when the note is on, 1 to 0 when note is off).
To give a pitch, you’ll send a voltage (usually 1 volt per octave.
So a note to a module (or 0-Coast) is a gate and a pitch.
From A4 you can also send CV values, and use the sequencer + LFOs + envelopes to shape such signal.
no stupid 
looks like a great module, and you never can have enough modulation sources (and VCA‘s )
You would usually use the gate inputs for the envelopes in the malekko. There is a seperate gate input for each envelope.
You could send four different gates from the A4 if you want.
But you can also send clock if you need.
As @LyingDalai mentioned, you have four different cv outputs from the A4, you can send them all to different modules, using different kind of modular signals (clock, gate, trig, volt/oct, lfo, envelope…)
wow that is super awesome! So glad I bought my A4 now that I am getting into modular gear. Saves me a lot on space and having to buy a sequencer.
You can do so much with cv on the A4, it can output pitch cv, gate, trig, clock and linear cv.
Each track can be the trig source (choose cv track and fx track as sources to have two tracks, that do not interfere with the four synth tracks in any way).
When you choose linear cv and modulate it with envelope or lfo, you basically send the env/lfo from the A4 and as you know, lfos and envs are pretty powerful on the A4.
Ofc p-locks and other seq magic also applies
I am able to connect my Elektron Analog 4 MK2 via CV A out to 1v/oct connection on the Doepfer VCO for my A100 Basic system. However, not sure how to hook up the A4 to sequence the modular? Any ideas?
What BS is it. BS1, BS2 or Basic Starter?
What are you having the actual problem with , connections on the modular or connections on the A4?
If it’s the modular you need to make a patch up , a basic eg. one…
VCO waveform out to VCA audio input, VCA audio output to your external mixer, ADSR output to VCA CV2 input.
You need to put the A4 CV out to the VCO CV1 input and the A4 Gate to the ADSR Gate input.
A100 BS1- at the moment trying to get OT to work over the Doepfer A100 MIDI CV. If I can get that up then I will be a very happy camper!
there are many threads on this forum already that explain it in detail.
But basically, set the second cv output to gate and patch it to the gate input of your envelope module.
Patch your vco to the filter, the filter to the VCA and the VCA to your output. Then patch your envelope to the VCA cv in. Now you can put trigs into your A4 cv sequencer track and play it like a A4 track…
