I don’t have maths I just have a function but they are much snappier to my ears.
Watch this:
What’s the module to the left of Braids ?

Thanks ned. Interesting module. I wonder if they’ll add support for other grid controllers, e.g. Launchpad.
I’ve been using my A4 to control a semi-modular synth via CV. P-locking CV works like a charm. But the synth also accepts midi input for note and gate. It would be good to be able to control it through both methods, using a disabled A4 synth track to do the midi duties and then the CV tracks to control non-MIDI parameters.
Does the A4 actually do basic sequencing of external midi devices? The manual is slightly ambiguous, and I couldn’t get it to work when I tried it.
I don’t think it does any external sequencing using midi, only CV.
Ooh, I love my morphing terrarium - so lovely sounding, and so many ways you can modulate those voices! Even with just an LFO on the X, Y, or Z axis… delicious.
@ izzymonkey
fairly interesting module
so i gather you input -cv trig- the axis with simple LFOs or analog 4 lfos?
The E350 will take whatever CV you throw at it. Envelopes, pulses, anything. CV is just CV. That’s the beauty of modular synths, CV is an open-ended and infinitely flexible control system.
Right, no MIDI Out on the A4. One of its biggest shortcomings IMO. Hopefully they will add it eventually but maybe the hardware just isn’t there (takes more than a MIDI jack).
Not sure if this has all been covered (so much in this thread…) but I just wanted to share a setup in case it helps anyone.
You can use the FX track as a dual audio VCA and the LFOs as accompanying AR envelope generators.
On an input of the FX track, set the VOL to min, set LFO mode to HALF, and set LFO destination to VOL. Now any trigs in the FX channel will trigger the LFO which will open the VCA, passing any audio coming into that input. Play with the LFO settings to get the desired envelope shape.
In order to do this with both input channels you have to use trigless trigs, just make sure you are resetting the appropriate lfo(s) per-step. This part can be fiddly, but it means that you can still use the FX track as source for CV/Gate.
A4 is great for sending pitch, LFOs (as you suggest), or triggers.
I’ll often use my mult to send a pitch from the A4 to more than one “voice” module at a time, e.g. E350, Hertz Donut, Braids. (They can be, of course, unison or detuned for whatever effect I’m after.) I can sequence this on the A4, or tell the CV value to track another A4 voice, which if I’m using an external controller, allows me to convert MIDI to CV easily.
Triggers to my Maths or PTG are great for weird & wild envelopes–sent onward to filters, E350, what-have-you…
Various CV values to E350 axis of choice… really the possibilities are limited only by how many things you want happening at a time. 
Ive got my rack arriving today so I can set up my anti osc and rs90 till all the other stuff arrives. Ive kept the A4 not so much for the synth which is great - but for the cv abilities.
Im gonna def grab one of the a4.euro adaptors - how good is the A4 with CV? Does it do +12v to-12v (I thought in the manual i read 10 to 10?)
Tips for the a4 being the primary clock source and sequencer - what can it do?
I think the clock is mostly stable - it does have a tiny bit of jitter so if you’re clocking something like the 4ms SCM or RCD which calculates BPM between every two pulses you might get some strange blips. Alternatively if you pull the clock out from the DIN sync jack it seems pretty stable, plus if you’re getting in there you can pull the ‘run’ logic line out as a nice reset for sequencers and clock dividers to help keep everything in sync.
It does +/-10v on the CV outs, and you would rarely need anything outside this range, if ever - especially in eurorack.
anyone sending clock from A4 CV track to modular gear?
I’m having an issue sending clock (and trig into reset not registering all the time on external gear)…If you are doing so with consistent success what do you have your length set to in CV setup on that CV out?
I guess I’m going to eventually need something like this:

to clock with midi and cv 
I’m using the A4 to clock my entire modular system. No problems whatsoever… what’s happening on your end?
main thing is that some trigs don’t seem to register
i.e. I set one of the CV outputs to type TRIG, V-TRIG, LENGTH (I’ve tried from 1-32), LEVEL +5V, then when I place trigs on the CV track it should send a 5V pulse to my gear that I’m going into RESET, I can see the signal on the Synapse but it just doesn’t reset on the module most of the time, if I manually press the RESET button on the module it resets fine…in this particular case I’m resetting on a sequencer which causes it to start at the beginning.
I suppose I could try a different TYPE…I’m just not quite clear what LENGTH refers to on type TRIG…manual says length of trig signals sent…but length in what measurement?
From my experience the LENGTH parameter seems to be the duration of the pulse where the maximum value is the time between consecutive clock ‘ticks’. It’s kind of like pulse width on a square wave oscillator, except for the clock pulse.
Here’s my setup. It’s changed a bit now. I use a Kenton Modular Solo MIDI interface to take note CV and Gate signals from the Octatrack and then I use the four CV channels from the A4 to P-Lock control signals. The Kenton interface also has four assignable CV outs and two clocks. I have the clocks set up at different rates and generally map the four aux CV outs to MIDI controllers on the OT. This allows me to use the OT LFOs.
Audio from the modular goes into the OT via a Thru machine so I can add FX and sample on the fly.
I’ve found CV control from the A4 to be much more accurate than anything translated from MIDI (locking exact delay rates for example).
For anyone thinking about getting into modular, my advice it to build your modules yourself from kits (my system is all DIY modules now). You will inevitably do a lot of module trading, which is part of the appeal and building your own is a good way to add value to your system. The case you see in the picture cost just £25 from Maplins and I installed a Doepfer DIY power kit inside.

I’m an early adopter of the A4 and a long time modular user. I never really used them together oddly enough. I’m still not really sure what the LFO’s are doing timing wise. 28x8 = what in the world of musical timing?!
Anyways, grabbed a Grayscale and even though it’s nothing more than a cable converter, really, I find that I’m instantly using the A4 and modular together more.
I’ve brought home my RYTM, A4 and a small modular setup from my studio space and am loving it!! SHould bring home the OT so I can start sampling all these noises!

I read this thread every now and then and can’t help be be in awe of the depth of knowledge that you guys have about this stuff!
Have experimented a bit with the A4 and cv - to minibrute and microbrute and minitaur (not all at once).
Brutes track the pitch but start out c - ? A bit wierd
Minitaur, well sometimes tracks, sometimes not. Always perfect with midi so thats the go.
Can anyone suggest a few “get me started” modules?
Would i need…
Envelope generator
Oscillators
Filter
?
Want to get something solid from thA4 cv. Track 6 just sits there waiting…
Have a cp-251 which gets some attention every now and then just so i dont forget what it does.
Just bought myself a Move 104 case to go with my Rytm and Analog4. I will have to buy a modules per month and so far I only have Intellijel uJack. Baby steps of course. Looking for a few filters with a bit of character and a few VCO’s.

Make Noise DPO for a dual Osc. Maths for envelopes, LFO & more. Phonogene for sampling/granular.
They would be my top 3.
Echophon is a wicked delay with pitch shirt
Mutable instruments Ripples is a cool filter as is the Koma but with the DPO wave folding you can live without filters to begin with.
