This is an older video, but after I played around with the AE Modular filters yesterday and "surfed" the resonances again I thought that this lady is doing a very fine job of picking the harmonics of her voice:
Now I wonder if this could be done maybe by sending CV from the SEQ16 to the Nyle filter which has resonance CV control and then using another sequencer to provide the fundamentals as input to the Nyle? Definitely worth a try as this would give you some level of polyphony from one oscillator.

Cool idea, would be worth a try! Totally remember this video haha, good ol YouTube Suggestion algorithm 😆

Definitely worth a try as this would give you some level of polyphony from one oscillator. Better still: if you have a pair (or more) of the NYLEs, you could use them in parallel and give the two filters some slightly different envelopes and different output levels. This would then get you MUCH closer to the multiple-formant nature of the voice when intoning multiphonics. |

Definitely worth a try as this would give you some level of polyphony from one oscillator. (I'm sorry for the need to tell about my life and the following long post, but I was so proud of one discovery about this subject, and I take the opportunity to tell to other synthnerds) I discovered something last week-end while listening to Eliane Radigue's Kyema : in some parts of the piece you can notice some melodies are played above the drone, those melodies have some specificities : they sound like feedback or overtones, they go through "discretes" notes and follow a scale, they have a major or minor feel to them. Listening to those melodies was intriguing for me cause I knew she brought the ARP2500 in France without a keyboard, and didn't think she used a sequencer (wich would make her process of using only 'wild sounds' and/or accoustic phenomenons less radical, and Eliane Radigue music never stroke me as not radical ^^ ) Of course, the use of resonnating filter was obvious, but I wondered how she could master melodies, and I think I found the answer : If you listen to those melodies they are like palindromes (so as a random example : one melody beginning with F then A then C# then D would need to end with C# then A then F). This suggests that Radigue was only going through the coarse of knob, changing the frequency of the filter up and down, and 'somehow' going through stepped notes. My guess for the how was that sending a chord through a resonnating filter, resonnance set high and changing the frequency, the resonnance would run through a scale (wich would also explain the major, minor feel I heard in the melodies). And I was so amazed when I managed to replicate this and the AEM! Basically, if you send one OSC through a highly but not self resonnating SVfilter and change the frequency with the knob, you will just hear the frequency continuously going up, just like a portamento, but if you send a chord through it, the same turning of the knob will end up in a stepped melody corresponding the chord under the resonnance. So with a chord through your filter, you don't really need a SEQ! |

Hi sycophante, That is a nice story and thanks for the tip with the chord going through the filter. Are you able to record or maybe film your patch? |

Having a peek at an older pic of Eliane Radigue at her 2500...
Aha! There ARE sequencers in there! Two, in fact...her right hand is working with the clock rate on a 1027, and right next to that is one of the most-coveted ARP 2500 modules, the 1050 Mix Sequencer.
I was listening to "Adnos II" the other night after reading the above, and thought to myself that there had to be a sequencer in there somewhere, listening to the behavior of some of the repetitive parts. But yeah, only one of those is a conventional CV/gate sequencer. The 1050, on the other hand, is something more akin to a Frames...several signals on different channels, then the sequential control steps through the different channels to shift from one audio source to another. While there's no shortage of CV/gate sequencers in present-day modulars, the Mix Sequencer only saw a modicum of adoption...EMW makes a version alongside Mutable's Frames, and there's a couple of others. But it's a neglected type of sequencer, to be sure.

It should be relatively simple to make a mix sequencer with an analog mux and an arduino (or even without).
Unless it does something more than just switch between audio sources.

The 2500's mix sequencer had an interesting scheme to avoid "clicks" when sources were changed from one to the next. Instead of simply switching (if I'm remembering this right...it's been a LOOOOOONG while since I had my mitts on one of these) from source to source, the module had a scheme in which the source channels were crossfaded very rapidly...a few milliseconds-ish, I think. Otherwise, you get a result more akin to what you wind up with on the ARP 2600, using the electronic switch to go from one source to another with lots of clicks and pops, because everything just snaps from one input to the other. |
