if you are running a norns script that sends midi out, you could use a midi to cv interface to connect that midi to eurorack.

Agreed, I just put one in this week. It’s extremely versatile – on top of 8 different filter taps, the octature VCO/LFO and great FM, it can be a waveshaper, “bouncing ball” bipolar envelope generator, etc.

I suspect that, between “resonant slew” behavior and the hold input and some feedback patching, one could get some very Wogglebug-like behavior out of it too.

Whilst looking through some youtube videos to learn some more/different uses of some modules I have I ran into this

In the example a filter ([ Synthesis Technology E440 Discrete OTA VCF is used to modulate a VCA.

I tried to replicate this behavior but was unable to. I’m using the same Intellijel Quad VCA but I don’t have the filter used in the video, I tried it with the Doepfer A-106-5 SEM filter and I’m getting not even close to the demonstrated effect.

I’m wondering what’s causing this. Is it purely a difference in the resonance behavior of the filter? Or is it something else?

#1793

seems like the filter is self oscillating and being used as a sine lfo.

Edit: Ah, seems like the A-106-5 doesn’t self oscillate.

from your link “The module does not feature self oscillation in contrast to most of the other filters of the A-100 system”.

#1794

As @Justmat says, any Sine VCO or LFO will get you in to similar territory - the filter isn’t doing any filtering here. The Sine is performing Amplitude Modulation on the sample he is sending into the VCA input. When the frequency of the Sine goes into audio rate, it begins to sound like Ring Modulation.

… so you could plug a VCO into the VCA’s CV input and achieve a similar effect. I like the 4-quadrant version of this amplitude modulation effect as found in e.g. moddemix or on disting A2 algo.

#1796

@Justmat @rikrak @eesn Thanks for the replies, that makes sense :slight_smile:
I did try it briefly with a since wave from a VCO but I’ll try again/invest some more time.
Btw despite what the webpage says the A-106-5 does self oscillate, but only at the very end of the resonance range and at a very low amplitude. Maybe it’s just not enough.
A uVCF (which does self oscillate) is on it’s way as well, so I should be able to try it with that in the future :slight_smile:

@eesn What does the 4-quadrant amplitude modulation do differently? Is it 4 times the same modulation with 90 degree phase offset or something totally different?

#1797

when the CV signal is negative, it inverts the input (In).
from Wikipedia:

A four-quadrant multiplier is one where inputs and outputs may swing positive and negative. Many multipliers only work in 2 quadrants (one input may only have one polarity).

Hey everyone,

I think we collectively have more experience than anyone could hope for on their own. So i need your advice. I recently dug into modular and generative or randomness based modular to be specific. Got some tracks recorded and really happy with the result.

https://www.modulargrid.net/e/racks/view/934060 here is my case for those interested.

I now want to venture more into sequencing world. My prior experience with sequencing is that i really didn’t like to program stuff, so i think something that can not be randomised in any way is not for me.

Currently i want to expand my system with this

What do you think of Rene as a sequencer that would be good for randomisation and generative? Are there other better options?

#1799

If you’re not adverse to a bit of (actually simple and intuitive) programming, Teletype is the most versatile option you can find for that.

I’m not sure i look for the most versatile option but more for most intuitive and immediate.

That said i definitely want to try teletype someday:)

#1801

I’d say a random looping sequencer, something like a Turing Machine, the original module by Music Thing Modular, or maybe O_c or Marbles (the latter two have a built-in quantizer).

#1802

I have Marbles alongside O_c already:) Marbles is really awesome.
I wanted to try and explore more “intentional” ways but leave myself some room to go back to randomness.

#1803

Both Rene1 and Rene2 are wonderful, modular tools, but a lot of what makes them wonderful is how imaginatively you clock them. Between PNW and Marbles, you should be well-equipped to make the most of Rene. I recommend immersing yourself in Make Noise’s Rene videos—if it’s feeling good, go for it.

Others are recommending shift register-based modules like Turing machine, but you’ve already got that in Marbles and O&C. Another module to keep an eye on is the upcoming Qu-bit Bloom.

My bad. I had not seen the first link, sorry.

#1805

This is definitely on the list. Too bad there not much demos of it on youtube:(

#1806

Video demos have never been Qu-bit’s strong suit… usually have to wait and hope that DivKid makes a video. Looks like we have a few months to go. The most intriguing thing about Bloom to me is its ability to derive a random variation and then go back to the original.

#1807

Agree. This is really interesting feature.

#1808

Sounds like you’re looking for a combination of a “fixed” sequencer and combine that with some randomization?
Sequencer can be many options, Rene as you’ve added to the rack is one, although I guess a Pressure Points might also work. A Z8000, Metropolis or any of the monome eurorack modules + a grid could be alternatives.

You can then combine this with one or multiple random sources via for example a precision adder.
It might also be an idea to try something like a sequential switch taking either a manually controlled or randomly controlled input to switch.

All of this is mainly about CV/pitch control, trigger randomization can of course also be done.

This video explains these options/combinations relatively well in case you want to know more about it

#1809

For a start you might want to try digging into the sequins app on your ornament and crime. It’s surprisingly easy to use and gives you nice ways to add, edit, reset, etc with CV input.
