Never tried Zadar, but it looks Interesting.

For me, building complexity from simple elements means that making changes is closer to the sources rather than being dependent on a complicated algorithm…

I have a pretty modest setup and while I don’t have a Cold Mac yet the thought of a Cold Mac, Maths, ochd plus some attenuation combo is much more exciting to me than a Zadar. And I try to stay away from menu diving which I think is required for one-module, high-level competency.

But as always can’t go wrong with both.

My two favorite modulation sources are the Zadar and the Omnimod. I think they’re excellent for coaxing out the really interesting quirks of especially filters, but I guess it depends a lot on what type of music you’re making (I’m mostly into things sounding a bit glitchy). I always use these two up long before any traditional LFO in my rack. Zadar is just excellent, I love it to bits, and it’s really not menu divey at all - it’s also the easiest modules of all I have to perfectly scale the outcoming CV of (the display will show you exactly the maximum amplitude of the CV coming out of it).

Thanks all. I think I’ll end up somewhere in the middle. Love CV mangling with my cold mac and mixers so far, and I think as long as I keep the screens to 1 or 2, and maintain some knob-per-function modulation, it will still be playable!

There are some great waveshaping tools which can preserve your modulation’s phase info while mangling the output: Shapeshifter, Piston Honda, Geiger Counter, Omnimod, and Flexshaper (my personal favorite) all share this capability.

hiya, looking for some help as I take first steps in Eurorack. Basically since, hearings sounds from this Klangbau filter module
Klangbau Köln Twin Peak Resonator - Eurorack Module on ModularGrid, I want to build a very small system around it (around 40hp). I am also going to get a radio music module and a function generator (needs a trigger) by the same maker, as he suggested them together.

I am bit unsure about options to trigger the logic module, and whether it might just be fine to use CV tools from Ableton, as I have a Motu interface which I think can send triggers at the right level. When I asked the maker of the modules about CV out of the interface he said this, which confused me;

"All devices should not be DC coupled, this blocks low frequencies and CVs. To work modular with a Max or PD patch, you need an interface without DC coupling and gain within 10Vpp.

Could someone help me understand this a bit better? I’m ideally looking to have enough cv control for the said modules but without spending too much or expanding the size. There should be space for a VCO in there and also a mixer or eq.

thanks for the help!

I’m a little confused by that statement too; DC coupling doesn’t block low frequencies and CV; AC coupling does: its a simple a high pass filter with a very low cutoff. The majority of audio interfaces are AC coupled as this eliminates DC bias in and incoming/outgoing signal and makes things like offsetting voltages to known ranges simpler. DC coupling is the “less common” design which is electrically simple but usually requires some sort of calibration to eliminate residual offsets.

Interfaces sold primarily for audio that offer DC coupling often only provide audio voltage ranges (around to 0-2v) but don’t live in the rack. The “within 10Vpp” is a bit confusing: I guess they want bipolar voltages, I.e +/-5V. It’s also not uncommon for DC coupled interfaces to cover 0-5V. Some devices sold specifically for CV (think the beatstep pro) offer extended ranges with DC coupling, but still 0-10V (no negative voltage). If you want negative voltages you usually need a device that lives in your rack where you get access to +/-12V supply. They can be large and moderately costly (check out expert sleepers).

My inclination would probably be to get some sort of pseudo random or generative sequence creator; maybe Turing machine? In such a small case you might want to consider a few (not too many as they affect usability) modules in the 2/3HP range (check out Erica synths Pico and 2HP). Also, if you are considering a 40HP system, perhaps consider a case with a 1U row to place a few utilities (I think the intellijel palette cases are quite popular for this).

I’ve often accidentally written “DC coupled” when I meant AC, and vice versa – looks like that happened there.

thanks! I need to check the voltage range of my interface (Motu Ultralite mk3) but think it should work ok. Only planning on sending CV out but just don’t want to break anything! I think at the other end it should just be a case of attenuating the signal.

thanks for the tip, the Turing looks interesting indeed. Re cases, its complicated a bit by the Resonator module being very deep (55mm) which is more than most low cost and small powered cases I’ve seen. Perhaps a custom case might be best. The Intelligel ones look nice too just so expensive!

@Starthief yeah must be the wrong way around, he was probably tired of my annoying questions!

Was wondering if there are any modular synth modules that do what Glut does? Pitch separate from speed and with granular clouds?

Basically can scrub through audio really slow at original speed but adding a gaussian cloud so there is no stutter

You can get similar things going in the ER-301

Morphagene can do separate pitch and speed in several ways depending on modulation sources. Nebulae 2 should be able to do it more easily. ER-301 is probably the best bet though if you want flexibility. Also the inbound ADDAC, IME, Miso modular granulators should all be able to do it with their own unique features.

Many thanks for the replies!

I’m curious how the Morphagene could have separate speed and pitch control? When I had one I thought they where tied together?

The varispeed knob does control both. But of you turn gene size knob so that you are only looping a small section of audio, the slide knob can control the start point of the loop, which can be effectively used as a time control.

You can also do stuff with the clock input too

If you’re still looking for cables with LEDs, this place seems to be a new run of them. Either the description is wrong or they’re using red for n̶e̶g̶a̶t̶i̶v̶e̶ positive and green for p̶o̶s̶i̶t̶i̶v̶e̶ negative, which would be a strange choice.

Thanks for the tip! Funny, I always thought red for negative made more sense but I’ve seen it both ways.

Ha, whoops, you’re right. I got mixed up while saying that it seemed mixed up.

Hi everybody,
I’m going crazy to understand how to obtain this simple process on my setup using just eurorack modules.
First of all, I wanna thank you for your help.
To have a sidechain is quite simple I know, but the trouble is that I’m using as main mixer a WMD Performance Mixer and I’d like to use all its features.
OK, I show you a picture of the setup so I can start from there.


I’ve a kick running from Blackbox OUT1 (red line) going to 333, from there the signal is splitted into two, one runs to the Mixer channel, the other to MakeNoise Function input. I’ve also a drone going from Blackbox OUT3 (yellow line) to another Mixer channel. That’s the signal must be triggered by the kick. The “-” out of Function is patched (green line) to the CV which must control the Level of the sinewave output in a “negative” way, so, when the kick plays the drone level has to reduce its volume.
The trouble is that the CV inputs in the mixer which control the Level are unipolar (0 +5) so, it doesn’t give me the chance to work as I wish, in the negative field. On the other side the CV inputs which control the Pan are bipolar and testing the same patch with the pan, I’ve seen there’s nothing bad in it, it works, so the problem is only that this CVs are 0 +5 and not - 5 +5.
If possible I’d like to use those CVs since they’re there already but I think the only way is to reach something like this drawing:

where the blue line is 0V and the negative shaping is something not in the “negative V realm” but upside down above 0V.

I’m a totally newby in eurorack so really, I don’t know if there’s a chance to do that or not. If there’s a chance using Function or I have to change it using other modules (I can do that). If I can use the CVs in the mixer or if there’s not any way to realize a sidechain using them.

Thanks A LOT for the help.
G

I don’t have much time to really examine your use case, but traditionally if you want to move a negative voltage “up” into the positive, you use an offset - so your -5 - +5 would become a 0 - +10. If you then want the range of the voltage to be between 0 - +5, you then need to scale that voltage down.

I don’t think you can do this with a function alone (it may be possible with a full maths). I think you need something that can scale and offset. Something like 3xMIA | would probably work.

Just a gentle word of warning - mixing and mixing-related functionality (such as side-chaining, compression, etc) can get very expensive in the eurorack world. You’ll quickly find that you need module x or module y to do what you need, several times over if you have a lot of tracks that need processing. You may want to consider if there are easier ways to do these things out of the rack.

You need constant CV to level of the drone that would drop when kick hits.
Full math can do this, the function doesn’t seem to have that.
Inverted envelope is what you need (or inverted and with offset).
