Who's using an A4 cv to Modular?

All sequenceing and clocking from A4 all modular sounds

nice !!! really great sounds !

Thank you.

Does anybody tried the inexpensive XOX Heart ?

A4 CV to a pair of semi-modular synths

A4 CV sequencing both the MS-20M and the Microbrute at the same time.

3 oscillators into the MS-20 filters, the LPF being modulated by the A4 envelope (fast modulation) and LFO (slow & random modulation). The FM and sync have been engaged in the MS-20M.

Finally, the sound from these 3 osc, after going through the MS-20 filters, go directly into the A4 Ext input in order to take advantage of a great amount of <3 Chorus, Delay & Reverb <3

I especially appreciate the junction sockets on the MS-20M. It functions like a CV cable splitter (you can see one unused at the bottom edge).

Here are the CV parameters of my system:

My first track from this setup:

Im in this boat now at the min. Was working fine the other day except tonight the A4 only sends out notes to the Temps Utile when the arp is on or I play the A4 key board. Won’t play from trig notes. Anyone experienced this?tks

ericg · 2018-01-21T22:54:22.576Z

ok noticed that I need to have Note length on the note page down to minimum unless Im using the arp.

KaOsphere · 2018-01-21T22:55:45.944Z

Got something similar the other day, solved it by tweaking the voltage output/clock div on the A4.

ericg · 2018-01-21T23:02:35.720Z

Ok thanks will keep that in mind. Was getting worried when it just stopped sending out notes or gates.

Dapifer · 2018-01-22T14:39:41.291Z

So you can send lfo via CV from the A4?

slicetwo · 2018-01-22T14:41:36.098Z

Yes.

Dapifer · 2018-01-22T15:06:20.453Z

Ah so you can attenuate the signal within the A4? I have some pedals that will only accept 5v so would be good to be able to attenuate it without having to buy extra cables.

avantronica · 2018-01-22T15:13:20.624Z

You don’t attenuate - you just define upper and lower voltage limits - this voltage high e.g. becomes the peak of an env or lfo

The Max is +10V , min -10V and it can be set in mV (10mV steps)

phil71 · 2018-01-22T23:01:45.575Z

Yes, you can.
In my table (a few posts above), the CV C is connected to the cutoff frequency of the low-pass filter of the MS-20. You just have to set the destination of one of the two LFOs from the A4 to the value of CV C

AGP1 · 2018-01-23T00:04:32.109Z

i have just the rings and clouds powered by my A4 right now. LFOs from CV b/c/d doing … stuff to both modules and CV A doing pitch on the rings (doesnt need a gate control here)

I’ve been looking at expanding into some other modules but not quite sure where to go with them. 4ms spectral resonator looks pretty special…

Dapifer · 2018-01-23T09:29:47.536Z

Thanks. So would I be right in saying I can use 4 tracks using the A4 voices, 1 track sending CV gate and pitch, and then utilise the FX track as CV for modulation?

avantronica · 2018-01-23T09:32:07.512Z

Not really - you can use the FX track for sequencing - so only pitch gate as modulation sources

You can use the CV track for sequencing and simultaneously for separate control of envelopes/lfos/clock/etc - the Value Lin(ear) Mode used to generate general modulation CV signals is only on the CV track as a destination

ylelocat · 2018-01-23T09:51:39.592Z

I think it depends which direction you want your modular integration to go.

After I started with Rings/Clouds I got Braids so I could have another voice to control from A4 (Braids already has a built in AD envelope). After that it was really about adding more modulation so I picked up Tides. Then I wanted some mixing/VCA so I picked up Veils.

The breakthrough for me was to get Pamela’s New Workout and its exp1 expender. Pam is now the main clock with MIDI out to A4. Check https://www.youtube.com/watch?v=Alu_cCDJIts where there is a section at the end on the A4.

After getting more modulation then I thought I needed to get more utility modules, I know they are important and I don’t understand them all yet, I just know I need them and it’s just a matter of understanding why.

So I recently added Links/Kinks and Blinds. I also got Ripple as an extra filter.

Next I can get more interesting flashy modules I supposed. I am thinking the ER-301 so I don’t need to get an octatrack.

Damn this rabbit hole…

A few days in with the A4MK2 and the most enjoyable thing for me so far is the CV possibilities and the audio in, I had no idea it would be so much fun. I don’t even have a eurorack system but it has brought the 0-Coast to life in way I didn’t think possible and to think I had been toying with the idea of selling the 0-Coast. I even got a little thing going with the Koma Field Kit where I sent a seq to the 0-Coast and the 0-Coast square out to the Koma so the DC Motor is vibrating in pitch with the sequence against a contact mic, basically having the motor as an oscillator. I discovered this little trick when using the Beatstep pro but now having the possibilities to play it through envelopes and filters makes it sound great and more than just a gimmick. Now I’m gonna try parameter lock my Moogerfoogers.

On the downside, this will probably now probably lead me down the eurocrack rabbit hole and subsequently ruin me.

I use the Analog Keys (and before it, the Analog Four) with my modular quite a lot. I have a room full of modular and vintage synths of all sorts, with lots of different voltage/gate/trigger requirements and I have never encountered a better companion for these instruments. I so loved using the A4 with my vintage gear that I swapped it out for the AK in order to make it my “master CV keyboard”. All four of the AK’s CV outputs are routed to a patchbay so that I can easily send any of them to any synth in the room. I actually wish I’d kept the A4 so that I could have double the CV on hand, but lacked the space. Maybe I’ll eventually make room for a MkII.

The coolest thing about the A4/AK is how flexible the CV stuff is. I’ve used it with my modular, Minimoog, 2600, VCS3, original MS-20 and Odyssey. Most of these have different requirements (s-trig vs v-trig, Hz/V vs V/Oct, 10v gates vs 4v triggers, .032v/Oct vs 1v/Oct, etc). The A4/AK never let me down.

For the past few days I’ve had a big ‘Berlin School’ thing set up in which the AK is sending 8th-note gates to the modular to act as a master clock. It’s also sending a master pitch voltage for each gate. I’ve got three different sequencers clocked to it and each set up to play a different sequence in C-minor. I’ve got the remaining two AK CV outputs sequencing an ARP 2600 - also in C-minor. The four other tracks on the AK are also sequenced. All of this is on a single pattern. By programming all sequences in C-Minor, I can then use the AK’s Transpose function to transpose all of the various sequencers in realtime. It’s really, really, cool.
