Hello and welcome.
An envelope follower is useful for getting a CV source from an audio input. Say you plug a guitar into your Instrument Interface, every time you pluck a string an envelope is generated, either positive or negative. You might want to use that negative envelope to lower the wet/dry of your effects so you can hear each note clearly followed by a blooming reverb or something. I often use the negative envelope generated by a kick drum to "duck" my bassline so the bass remains a little clearer. Or maybe you want to get an auto-wah effect by using the positive envelope to open a filter that your guitar is going into. Those are a few uses of an envelope follower.
Have fun!

Looks like fun to me.

Yes, I believe this is what you are after. If I'm not mistaken, the +12 db is for line level (your Octatrack cue outs) and +18 db is for instrument level guitar pedals. There is a switch for +12/+18 on each set of ins and outs. The Xchangr would allow you to have one stereo or dual mono set of inputs to your modular, and two stereo or dual mono outputs to send back to your Octatrack or to an external mixer, effects processor, etc.

I think the Moog semimodulars are awesome. I started with the DFAM (still have it). Those are a great pairing, and an excellent way to dip your toe into a larger system. Figure out everything they can do and then add modules that complement them and offer functions that they don't have.
Have fun!

The truth is, what you're going to have to do is just take the plunge and get some experience. There are all sorts of variables that are highly individual but won't make sense until you have some modules in front of you. This individualization is one of the beauties and joys of modular, but also makes it difficult to give advice. Everyone has their favorite manufacturers and modules, but that doesn't mean you'll like the same ones.
Do you like one-knob-per-function modules or are you okay with menus and button combinations? Do you want lots of panel space to tweak knobs, or are you okay with having tiny knobs and jacks all bunched up together, making it hard to get your fingers in there? And so on...
My advice is always to do your research and go slowly, only buy modules that solve problems that you cannot solve with modules you already have, don't be afraid to sell off modules that don't work for you, invest in a bigger case than you think you need, and have fun. You probably will spend more than your current budget in the long run.

This video offers some food for thought. There's a running gag amongst modular users that you can never have too many VCAs, and that's something that beginners don't usually understand at first. You don't have any VCAs here, and I don't see any mixing solutions either. That's where I would recommend looking.
Have fun and good luck!

Intellijel's Shapeshifter is an incredibly powerful wavetable oscillator. It can do a LOT. I'd recommend looking there first.
Good luck and have fun!

I'm no Behringer fan, but the RS9 and 960 sequencers were EXACTLY what I had been looking for as a sequencing solution. While I'm mostly using the RS9 to sequence drums externally (Vermona DRM1 MkIV), I still use it to trigger events in the rack. I've tried so many different sequencers and never felt fully satisfied with any of them until I went with this inexpensive yet powerful combination. Aside from the huge chunk of real estate I'm sacrificing, I have zero complaints.

VCO out should go to the audio in of the Wasp filter. The out of your Tilt should go to the CV input of the Wasp and Gristleizer (for a classic subtractive patch). Out of the Wasp into the Gristleizer input. Gristleizer output into your mixer. Adjust settings of Gristleizer bias and Wasp level and frequency to taste.
Have fun!

i he really use piston Honda where is that verified?

He's always modifying his live rig from the discussions I've watched and heard. This live rig is from 7+ years ago, so I imagine he's using something else completely different now.

I think I'd go with the uJove, unless you need the high pass of the Ripley.

A traditional subtractive patch would be something like...
Pitch sequencer > VCO v/oct input > Filter input > VCA input > Effect > Mixer
Gate/Trigger sequencer > Envelope generator > Filter/VCA CV input
LFO/S+H/Random/Noise > Whatever sounds cool

Good luck and have fun!

My concern here would be playability. With minimal stuff, you want subtle changes over time. Turning all of those tiny knobs so close together when a bunch of cables are patched will be difficult, if not maddening.
Befaco Percall might also be a module to consider here.
Good luck and have fun.

Looks like a lot of fun! Do you find the Morphagene and Data Bender redundant at all for glitchy stuff? What kind of music are you doing with this rack?
Every time I think I'm finished building my rack, I think of something new that I absolutely MUST have within a few months. Haha
Have fun with it.

The SBG might be fun if you have a lot of pedals.
I have the mmMidi and Pamela's New Workout. Great modules. You should be able to set up some pretty cool sequences via Digitakt as your master MIDI device.

No, I'm just suggesting that you can switch octaves from the Digitakt.

I would probably keep the mmMidi and sequence from the Digitakt. That would probably eliminate the need for the Beast's Chalkboard since Digitakt has good MIDI sequencing capabilities. Do you need the HPO? If you got the Tangle Quartet, you could probably just attenuate the signal from there on the way into the Digitakt or whatever you are using as a mixer.

Yeah, I feel like I would want the Tangle Quartet in there.

What will you be using as VCAs? Does the Mum M8 have a built in VCA?

I have adjusted and refined my setup many times over the past five years. I've bought, sold, re-bought, and rearranged countless modules and have finally (mostly) settled on what works for me. The general idea is aligned with the signal flow of a traditional fixed-architecture synth. After so much experimentation, I know how I usually use each module and I have arranged them to have the shortest cable runs possible. I like to constantly tweak knobs, so keeping cables as short and out of the way as possible is important for me. I try to have my signal flow going from left to right and top to bottom so I can avoid too many criss-crossing cables, which is visually important for me so I can remember where everything is going. I'm getting too old to remember how I've routed everything otherwise. Haha
Good luck and have fun!

Plaits firmware 1.2 has a decent string machine emulation along with a good chord mode.

Contact the manufacturer, otherwise familiarize yourself with basic principles of compression and you should be good.
Have fun and good luck!

Circadian Rhythms is a gate/trigger sequencer. I don't believe it has either pitch CV outputs or MIDI outs. The Wasp is very limited in its eurorack connectivity, so you will need a MIDI sequencer of some sort, like a Keystep or something to get gate and pitch sequences happening since it doesn't have gate and pitch inputs.

What sequencer are you using? What modules are you trying to integrate with the Wasp?

I'm about 99.5% happy with my rig now, and I still come to see what's new every day. I'm still waiting for someone to make a voltage controlled "Talent" module. I'd pre-order one of those. Haha.

This one looks pretty neat: https://modulargrid.net/e/jroo-music-machines-jroo-loop
I was very close to getting one of these but went with a Strymon Volante instead. The pedal suited my needs a little better.
Let us know what you choose. Have fun and good luck!

Probably just coincidence. I had one for a little while and it was a fun sequencer. The sliders were a little fiddly and using the same sliders for multiple functions got kind of confusing, but it's definitely a powerful sequencer for a smaller rack. Very hands-on, low hp, and inexpensive. I'd say if you find a good deal on one in good shape, you will probably enjoy it.
Have fun and good luck!

I enjoyed the Eloquencer for gate sequencing but I figured out that I like a more old school approach to pitch/CV sequencing (960 or Doepfer Dark Time style). I didn't like using a single knob to program notes and probability. I think I'd be looking at a Metropolix if I was going to get something more modern with an old school hands on feel.
Let us know what you decide! Have fun and good luck.

Man, this is great. Good to see you again!

My understanding is that Surgeon uses an Electro Harmonix looper for live looping (can't remember which one), and an Octatrack for some sequencing duties. I seem to remember reading that he doesn't especially care for the Octatrack, but keeps coming back to it for some reason or another. I can totally identify with that. I keep trying to incorporate Elektron gear with my modular stuff, and can never quite get into that flow.

Yes, I would recommend that you don't sell Pam's just yet. It's magic may reveal itself to you later. I have mine mostly as a "set and forget" brain that ties my entire system together with a few channels that I change from time to time.
As MCGM said, the Maestro and other basic/utility modules will be useful. I like Voltage Block a lot for a sort of Elektron-style "p-lock" modulation sequencer. That might be a fun addition for you.
Have fun and good luck!

What are you trying to achieve that you can't do now? What kind of music are you making?

Usually called "DJ" filters. Erica Synths makes one:

Just a heads up, the black Maths is unobtanium at sane prices. I'd recommend looking at the standard silver panel if you are dead set on Maths.

Across the industry I have experienced a +30% failure rate of Eurorack modules. This is unacceptable. These companies should be held responsible for their horrible, low quality production practices.
-- Humdrum

30% failure rate?!? I've not had a single module fail. Is the power in your rack suitable? Seems there might be something else going on.

I'm using an external rackmount compressor (Focusrite Compounder) at the moment, which works pretty well for what I'm doing. I have been tempted many times to get the L-1 Stereo Discrete Microcompressor in my rack though (https://www.modulargrid.net/e/l-1-stereo-discrete-microcompressor). It takes up a good amount of rack space but seems to be the closest thing to a higher end compressor in sound quality and features that you can get without spending a crazy amount of money.
Have fun and good luck.

I believe you have to have a Unicorn account. It's an annual subscription. Totally worth it to support the site.
Have fun and good luck!

I have the After Later Audio Pixie full size clone with the newest firmware. Works and sounds great. Kind of ugly though.
Have fun and good luck!

Nice! Gives me kind of a brooding Warp Records vibe. Thanks for sharing.

Really enjoyed that. You took me on a journey. Thanks!

Matrix mixers are recommended pretty frequently here, and I would suggest investigating how you might use one of those to inject some life into your current workflow. They're fun for feedback patching, combining modulation sources, and using as parallel routing. The Doepfer A138 is awesome but large at 20hp. I'm sure there are smaller options.
Have fun and good luck!

All I can really say is that you only have too much of something if you don't use it and you don't have enough of something if you find yourself constantly reaching for something that isn't there. Other than that, it looks like a fun system if you enjoy the sounds and workflow. About 9u / 104hp is where I started really enjoying my system.
Have fun and good luck!

Looking at this from the perspective of a customer, I would personally assume the risk if I used Paypal f&f. I understand there is a risk going into the transaction this way. When the postal/shipping service receives the item, the seller is absolved of responsibility for the package. It would be kind, and expected, of the shipper to help with filing lost package claims and things like that, but the seller completed his or her end of the transaction. Your concern should be with the shipping company, and demanding an adequate response from them. That's how I look at it, anyway.

Sequencer > square vco > filter > vca > fx1 > mixer? No...

I feel attacked. This is all I've been doing for the last week. I'm going through a Tangerine Dream "Rubycon" phase again. Haha

Yes. That's what I suggested initially. Give it a try and let us know if that's what you were hoping for.

Check out the Noise Engineering Quantus Pax if you want multiple quantized Voltage Block channels added to multiple random cv signals.

I think what you may want in this case is a precision adder.

*Edit: I just looked at your rack. Try adding the two signals together in the middle section of your MI Links to see if that does the trick.

I agree with 33PO's recommendations and would also add Schlappi Engineering.
Good luck and have fun!
