- In this video I demonstrate building chords with Eurorack by sequencing and mixing multiple monophonic oscillators. I hope it is useful! Thanks for watching!

My gosh! Love the module list in the description! So good!
This is a really fun idea! Love using Bard Quartet and was just thinking I need to explore it’s capabilities to do chord sequencing. I wondered if it could be fun to set up the notes on the quantizer itself using the harmony presets and then you could use mimetic to go to different chords as you choose. You’d basically be making groups of full chords to then select with mimetic so you could have 4 different progressions selecting between 8 chords. From there, there’s probably so much you can build on from using the track and hold. Mind you, the way you did it you could also add in modulation summed with what’s coming out of mimetic to provide some more motion.
Basically, I’m saying this is a wonderful patch and amazing thought started. My fave kind of videos. Thanks so much for making it! The chords sound soooo good!
Very sharp! What you describe is what I was planning for my next video! Using Mimetic just to advance the chords, but programming them using the scale and harmony controls on Bard Quartet instead of tuning by hand with Mimetic.
@@Perceptes Haha whoops! Sorry to spoil it. Can’t wait to see it then! I feel like there’s so much cool stuff to be done in and around this idea. Could be so epic! Excited to see what you discover.
thankyou
Does the bard quartet not simply show the active note on its LED keyboard? Using the Mordax seems kind of cumbersome, unless it was used mostly for didactic purposes in the video of course. :)
Yes, you can see the pitch, but not the octave number. Of course you can use your ears to determine that, but it's nice to see it all in one place!
sounds like a bitcrushed organ. :)
Good description!
"The hard way." Not a dig, just saying, this is more or less brute forcing it. One advantage of doing it this way instead of using something like harmonaig is that you get the voice leading right. If you're doing a straight triadic chord progression, it will sound vastly better if you don't just move a "root 3 5" chord up and down. Instead, as you've done here, move each voice as little as possible.
Parallel voice leading (where stacked voices all move up or down from note together) is usually less pleasing to the ear than contrary motion (where one voice moves up and another down). Parallel octaves and fifths, where two voices move to and from an octave/fifth, are particularly noticeable.
As to alternatives, I'd guess that midi to CV is probably simplest.
Also, just consider whether you really want to do it in modular. In this case, with four very different oscillators, you can articulate each voice independently to emphasize a melody or get dense timbral motion.
VCV Rack might be a good tool if you want true polyphony in a fully modular instrument.
Basic instruction for western classical voice leading quoted from Wikipedia: "Common-practice conventions dictate that melodic lines should be smooth and independent. To be smooth, they should be primarily conjunct (stepwise), avoid leaps that are difficult to sing, approach and follow leaps with movement in the opposite direction, and correctly handle tendency tones (primarily, the leading-tone, but also the , which often moves down to ). To be independent, they should avoid parallel fifths and octaves."

Thanks for the additional detail on voice leading! What I show in the video is, of course, an example of the technique. You're free to orient the voices any way you like with this approach. I'm planning a follow up video using more intelligent settings on the quantizer to make the process of setting this up less painful. And of course, as you say, it would all be easier with MIDI and a fancier sequencer. I could have used my OXI One which has a chord mode!
