Nice overview and beautiful examples! The reason why the polyrhythmic and polymetric approach create the same result lies in the use of the lowest common multiple. If you look closely you notice the first "polymetric" sequencer (length 7) is actually playing the 5s, so the part of the first "polyrhythmic" sequencer (hits 5). That's because the length of the "polymetric" sequence corresponds to the gaps(*) (including the beat) in the "polyrhythmic" one and each the of the "polyrhythmic" sequences has either 5 hits and 7 gaps or 7 hits and 5 gaps. The product of hits and gaps in between is the LCM. So the polymetric version is a compressed version of the polyrhythmic one: The polyrhythmic approach uses a constantly repeating pattern which contains a lot of redundancy. On the other hand the 1 in the corresponding "polymetric" sequence plays every note of the "polyrhythmic" one. Where the differences start to show is when you add a third rhythm, e.g., a 3: In polyrhythmic land you just continue the same principle: Length of the pattern: 3 * 5 * 7 = 105, 3 patterns with 3, 5 and 7 hits respectively. In polymetric land you can't just add anther sequence with the length 3. Instead the length of each sequence must correspond to the multiple of every other rhythm, so for 3 it's 5 * 7 = 35, for 5 it's 3 * 7 = 21 and for 7 it's 3 * 5 = 15.Of course that's just the lengths of the corresponding gaps in the polyrhythmic patterns of length 105. (As you include non-mutually-prime rhythms you can decrease the length of the patterns using the LCM.) So in the end it's just a question of what you look at: Do you look at the length until the whole pattern repeats and the number of beats in each patterns during that length? -> polyrhythmic approach Do you look at the period/gaps between each beat? -> polymetric approach The underlying principle is the same: When do compositions of prime or coprime periods repeat? Polyrhythms and polymeters are just two ways of looking at it. That's what I find so beautiful about polyrhythms and euclidian sequencers: It's all just integer math :) (*) "gaps" is a poor choice of nomenclature here, because it's not actually the gaps but the length of the period until the pattern repeats internally, but it's easier to understand and describe, so I'll stick with it.

Nice video, on the last question my guess is that if you add additional steps in the sequencer maintaining the same length relationships, it will behave as a Polyrhythm with a different time division, because regardless of the number of hits, if they restart on the next phrase, on the first beat at the same time, it'll be a Polyrhythm.

On your question around if the last patch example stays as a "Poly-rhythm" or "Poly-meter" if you add additional triggers on the 8-Step Sequencer.... I would think it is still a "Poly-Rhythm" since the first step/trigger is always ON (hence, similar to the Euclidean Sequencer).

Not related to this video but something that I find difficult to learn is when I apply LFO to any parameter of my nord it goes from 0 to max and return while staying at O and max for some time , actually I want to control the range of the action without them staying at the max and min value for some time. How should I do it?

Well, it sounds like the range of the LFO you're using doesn't match the modulation source so try and use the Dual Attenuverter from Befaco, for example, and set the right range for your LFO. Let me know if it works.

I guess I have a question back to yours: in the Euclidian case, does 'as evenly as possible' mean as long as they occur on the sequence pulse? Or does it mean, they will occur on the mathematically correct, real number, division point within the interval between one loop beginning and the next beginning?
@rarebreeds4346

To make a Euclidean rhythm you take a bar and split it into a number of equal length beats, say 8. Then pick the number of onsets (the beats that should be played aloud), say 5. Then you place those 5 beats onto the beats in the 8 beat bar in a way that spaces them out as evenly as possible, or in other words, so that the distance between each onset beat is as even as possible. For the 5/8 example this turns out to be "XX.X.XX." So it's more like your second thought, but after dividing the loop into 5 evenly distanced beats, you quantize them to the nearest 8th. The quantizing bit is what gives you the interesting rhythms, especially when the number of onsets isn't evenly divisible into the number of beats in the bar. The Euclidean rhythm wiki page has links to papers on it if you're interested.

yeah, as Rare Breeds said, it's more mathematical, and the quantization gives everything the interesting rhythmic result.
