Hi Nerds,

under https://youtu.be/ibsKATUop9s https://youtu.be/Y2kCT88P9hc is a slightly edited version of my first video. I apologize for the poor camera - my phone holder for my tripod got misplaced somehow and thus I had to hold the camera by hand.

The overlayed text tries to explain what I've done and how things work.

A large part of the stuff going on is the NerdSEQ. I'm not aware of any other sequencer in eurorack, that could do anything remotely similar.
As with many things the interpretation of the music isn't completed. In particular the dynamics could use some more work. I also might eventually change the sound of the various voices though I currently have no idea in what way.

I'll appreciate comments and in particular regarding things that could be improved.


Kind regards,
Michael

PS: The first couple of seconds there is no sound (that is intentional)
haha! very nice! love the Bach.
I only can say this is an exceptional work! I definitely
recommend anyone to watch it. ❤️
Absolutely epic.

Dare I suggest that it could make for an awesome community project, perhaps for during the holidays, if interested folks with a CV 16 could run your project file (modified if/as they wish) through a patch in their system and then have everyone post recorded results? Big Grin Imagine all the variations!

Here are the files that I have to document the project:
https://qata.de/upload/NerdSEQ/Bach-BWV1...tsicht.svg
https://qata.de/upload/NerdSEQ/Bach-BWV1...tsicht.txt
https://qata.de/upload/NerdSEQ/BWV1048E.NRD
https://qata.de/upload/NerdSEQ/BWV1048I.NRD
https://qata.de/upload/NerdSEQ/SOB-Modul...1048-1.mp3
https://qata.de/upload/NerdSEQ/SOB-Modul...1048-3.mp3

The first two are the Patchbook Image and Sourcefile that describes the whole patch.
The NerdSEQ Projects are for the current V1.25A: BWV1048E is 3rd and BWV1048I is 1st Movement of BWV 1048.
Finally recordings. The soundfile of the 1.st Movement differs slightly from the audio in the video since I found a few glitches in the dynamicsof a few voices and corrected them. I also finished the dynamics for the 3rd movement and recorded it. No video yet. That will have to wait until after xmas.

My NerdSEQ configuration is:
NSA1: More CV16 (used on tracks 1&2 for violins and violas)
NSA2: More CV16 (used on tracks 3&4 for celli and basso continuo)

Have fun playing with this stuff Smile

If there are questions feel free to ask.

Kind regards,
Michael

PS: Forgot to mention: The note CV outputs are switched to -5V - +5V. That decision I had made early on for a couple of reasons and once I had entered the majority of the notes I did not wish to change that (too much work and too easy to introduce errors). Therefor middle C ist in fact C-7 and A-7 is supposed to be 440Hz (or whatever your prefered reference frequency is). The Envelopes and overall dynamics are set to 0V - +10V.
Wow, Michael. I’m just quickly catching up on the forum before the day gets going here, and so have yet to look at the attachments themselves, but thanks so much for sharing so willingly, and so comprehensively.

I’ll definitely be trying to do something with this, and I hope some other folks join in also!
You're welcome Smile

I'm looking forward to what others might make of this !
Wow. I haven't got that many cv-controllable oscillators and converting it to midi to play outside my modular setup would take some time - so I will just have to lean back and say wow - what a great work you did on that.
Though I had to spread the work out in little bits and pieces during the last month and a bit, it is finally done! YouTube says it is still processing the HD and 4K versions, though I just watched it in 4k60 so it should be available like that for everyone.

You fine folks here get first crack at this before I spam a discord or three some time on Sunday.

There are some decently-detailed notes in the description, but I’ll paste them here for ease of reference and to whet the appetite:

NerdSEQ project file courtesy Michael Gerdau. You can watch his original version here: https://www.youtube.com/watch?v=Y2kCT88P9hc After watching his version I suggested it might be interesting to see other people run his NerdSEQ project through their modular synths and he provided in spades, with not just the project files but also comprehensive information about his patch! To avoid excessive rewiring I refrained from utilizing some of the dynamics control in the project file, but ran it essentially unmodified otherwise. Thanks for the massive sequencing and sharing effort Michael!

Apologies for the shaky camera movement and imperfect final placement, but I’m not going back to re-record and re-upload this monstrosity. Wink

Two sets of ten voices are featured: one focused on tones drawn from retro computing, the other not. The movement is performed thrice, as follows:

00:00 Both sets of voices, cross-faded periodically by AXYS (from Ochd through tanh and DATA)
06:03 Just the non-retro voices
12:06 Just the retro voices

Driving both sets of voices is a NerdSEQ with More CV expander feeding three DROID modules. The DROID modules run a patch which for each of three or four incoming pitch CVs generates two pitch CV outputs, one for the retro voices and another for the non-retro voices. The DROID patch allows each of these eight CV outputs per DROID to be individually octave-shifted (shame on you, 0-5V module makers!) and calibrated. The majority of these pitch CVs are then wormholed toward the VCOs via Doepfer multicore modules, tidying up the patch, but a few which are not a part of my standing control-rate patch are connected directly. Michael’s NerdSEQ project also generates all envelopes, and these are wired directly into 20 VCAs via a collection of buffered multiples. If you notice envelopes firing during the video, I admit patching some additional things for greater blinkenlights factor. Smile Some module spotting awaits you.

Starting with the simpler retro voices, these feed a Doepfer octal VCA and a couple channels of Veils. Individual outs are then routed to ten channels of a Mackie LM-3204 stereo line mixer by way of an nw2s 16-channel balanced output module:
- Two Twin Waves modules provide four oscillators, all 2-bit saw waves.
- Threshold provides four oscillators. Three reduced-duty-cycle pulse waves and a NES triangle.
- Akemie’s Castle provides two oscillators, leveraging some of its weirder waveforms with one under light FM.

Onto the non-retro voices which feed ten channels of the LM-3204 expander, via further nw2s 16-channel balanced output modules, and are patched roughly (from first violin on down) as follows:
- Demon Core into Neutron Flux into Koma Dual Discrete VCA
- Braids into Fold 6 into Tallin
- Trident into Morpheus into Tallin
- Generate 3 into Filter 8 into Koma Dual Discrete VCA into tanh
- Angle Grinder into 860 VCF into Veils
- Bang into Pura Ruina into Red Dragon into Veils
- Osiris into Moon Phase into MUTON
- E300 Ultra VCO into Sonic XV into Koma Dual Discrete VCA
- A-111-5 (with open filter) into C4RBN into MUTON
- E300 Ultra VCO into V Shape into XaVCF into Koma Dual Discrete VCA

[Shower thought addendum: Early on I explored use of wave folders, distortion units, etc. and used a few, but ended up with less patched in than I figured I would. I think they can definitely help get closer to the target waveforms, but I was just getting tired of testing permutations as the project went along.]

Mixing and effects: The Mackie LM-3204 stereo line mixer, and expander, receive audio from nw2s 16-channel balanced output modules and feed stereo main (for the non-retro voices) and aux (for the retro voices) mixes, along with FX sends, back into the modular via an nw2s balanced 8 input / 8 output module. Stereo submixing via HN 4x Stereo Mix modules feed Erbe-Verb for reverb and reassemble the non-retro submix with effects. The retro voices are mid-side processed, simply for easy adjustment of stereo width, by SumDif and a channel of LEVIT8. AXYS blends between the retro and non-retro submixes. This is automated via Ochd (shaped by tanh) during the first phase, and adjusted manually for the second and third. AXYS feeds TX2 for balanced output.

Audio processing, and recording: TX2 into Octatrack (just passing through my standing setup) into Analog Heat (factory saturation preset; I literally just got AH, so a preset is what you get Wink ) into iPhone via USB. Audio and 4k60 video were recorded together using the built-in camera app and are unprocessed aside from a camera app colour preset and YouTube’s encoding.)
Nicely done. The non-retro voicing sounds more interesting to my ears [you own an impressive lineup of stuff Smile ]

One thing that occurred to me w/r to my original project after having discussed this with my father in law over xmas is, that my use of the LFOs for vibrato does destroy the harmonics. At least to some extend. Especially some of the faster parts do sound ever so slightly out of tune.

I therefor am currently working on refining the projects to enhance the vibrato. I have two possible solutions:
1) Use my newly acquired Droid to create delayed vibrato (basic patch works and sounds nice). However I lack stackable patch cables to do this just now for all voices.
2) After seeing what the delayed vibrato created by the Droid looks like on the scope I realized, I probably could achieve (almost) the same using FX inside the NerdSEQ.

I will definitely try out 2) and if I consider it an improvement post updated versions of the projects in this thread.

In any case, I like your version and enjoyed watching it. The idea to use envelopes for greater blinkenlights factor is cool!
