Eurorack: discussion, advice, learning, questions

[chorus7]

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

[Jonny]

You can get similar things going in the ER-301

[crunchydrums]

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.

[chorus7]

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?

[crunchydrums]

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.

[andrewhuang]

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

[stvnrlly]

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.

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.

[kveye]

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).

I find making a cat’s meow patch, or a patch that sounds like a cat meowing is fairly easy. Modulating pitch and filter with envelopes, while playing with the attack and decay gives some fun results. On the other hand, I have no idea how I would go about making a patch that sounds like a dog’s bark. Any suggestions/ creative ideas?

[crunchydrums]

Tonal aspects of growl sounds are pretty easy to create with audio rate modulations where the carrier osc is a higher frequency than the modulator. Slower pitch bends would also be useful since they aren’t a static pitch. Running thru a formant filter or comb filter would add some depth

Would also add in some bandpassed noise or a “tearing” texture with a sampler/granulator.

Would mix the signals and send thru VCA with an easily manipulatable envelope (like maths)

Then run both layers through a reverb with a short ish decay and compress/saturate.

[csus]

What a great recipe for a barking patch! My first attempts were pretty chaotic. I think this is something Ill have to practice and play with to accomplish. A lot of great learning in here! I’ll share my results sometime down the road.

hello

I’ve got one and it’s perfect as an end of chain stereo summer. I use it with a matrix mixer (AI Synthesis 008) and it’s perfect for stereo effects, like the NE Desmodus.

Great quality highly recommended. I’m also interested by their last Chaos module…

Does anyone know of a reasonably comprehensive list of modular functions? I’m trying to figure out what I’m missing (in eurorack). Not that I’m trying to check off every imaginable box or anything, just wondering what might be out there that I’m not consciously aware of.

Thanks!

[Voiron27]

The book Patch and Tweak gives a good overview that is euro specific and Allen Strange’s Electronic Music: Systems, Techniques, & Controls is a classic covering the basic building blocks (there are good pdfs of the second edition floating around).

[eblomquist]

I’m curious about the two channels with extra gain inputs. What have you used those for and how do they sound?
Thanks!
