Yusynth steiner parker voltage controlled filter diy home build

Another yusynth project completed. this is the Steiner Parker VCF as found on the yusynth.net website by Yves Usson.
A quirky aggressive filter that certainly has character.
all music within this video made by Markus Fuller - Jason Lee - Dan Ward.

Mate, you're addendums are legendary. You've helped me understand why I've had trouble matching transistors in the past. I love my Matrixbrute so I'm also look forward to building this one for my eurorack 😎😎😎

[@Roderick_Legato]

Markus, I love the direction you're going with these new videos, and the discussions they inspire!

[@ogasi1798]

Mr Fuller - thankyou. As always your vids are presented in a great fashion, they are informative and easy to follow.

[@jkuebler89]

I really enjoy watching your process of populating these boards. I appreciate that you are doing it on protoboard to show how anyone can replicate. Great work! Please keep em coming!

[@LaggyKikee]

The huge price of modular puts me off, but these videos of yours are inspiring me to make my own modules and start a eurorack

[@markusfuller]

Kyxe Music Yes have a look at yusynth.net theres practically a whole synth you can make and many modules have the option for eurorack or 5U power options. I think this last unit must have cost about £20 in parts.

[@freeelectron8261]

Love the YUSynth modules - I have built all the main ones (vco, vcf, lfo, vca, etc). Just started watching your vids. Great work! Hello from Queensland!

[@PorchBass]

A rather elegant realisation for the home builder. Good work. Great panels you've got that down.

[@krmelectronics]

The laser etched panel at 12:58 looks fantastic. I also really like the board mounting brackets at 14:30. Doubling up on the holes for the pots is an excellent idea.

[@markusfuller]

Synthesizer Keith Thank you Keith. the laser is a new addition to the workroom and im having great fun experimenting with it.

[@Roderick_Legato]

You could start a side business with that thing doing custom engraving.

[@markusfuller]

Ig Oluffson I got the 20 watt fiber laser engraver with rotary module. i dont know the exact model number something100 . but it works very well and is very fast and sharp.

[@Roderick_Legato]

Something like this one? www.amazon.com/MCWlaser-Portable-Desktop-Engraving-110x110mm/dp/B01DP3SVIG

[@markusfuller]

sdm02 Yes thats the same one.

[@Romaindeud]

Very nice panel ! This Steiner is my favourite Yusynth VCF. Still have to do the ARP one. Thanks for the video ! :)

[@nozzlegoblin1]

I built this module as well. I highly recommend to VCO. It tracks very well, and sounds great. I'd love to see you build the filter bank. I think it's great that you are featuring the Yusynth modules.

[@perli216]

Thank you so much for this video! I wanted to build yusynth modules for a while but didnt want no get into etching. Thank you.

[@markusfuller]

Thanks Merlin. I can Etch boards but I wanted to start these video's off by showing that these units can be completed without etching or cnc or ordering ready made boards. that way anyone should be able to get started on making a modular system of their own. I hope to eventually work my way through all the parts needed to build a whole synthesizer. best wishes from Markus.

[@michaeltinnin]

I WANT A FREAKIN LASER ETCHER !!!

[@shreddz]

I have an Arp Yves filter I need to finish, trouble shoot an lfo and adsr and I'll have a nice little modular finished! All perfboard, some tips; I manually layout but definitely use Yves starting points on his pcb's aswell. When placing components highlighters work great for flux hazed eyes! And as a final check I go through and beep out the schematic with the multi and mark it off to be sure. Thats also good for troubleshooting! Sometimes the wrong pin gets grounded

[@soupforare]

Love your practical approach to everything. I think it's something dearly missing from electronics/engineering pedagogy, at least here in the states

[@markusfuller]

Thank You. though you do have some very good electronics guys in the states that I enjoy to watch on youtube. Im a big fan of synthesizer keith and mr carlson amongst others in the States.

[@McTroyd]

@@markusfuller Unfortunately (for us Americans) I'm pretty sure Mr Carlsons Lab is Canadian.

[@vegettoblue8705]

The steiner parker Is my fav filter , when the resonance goes up the volume doesn t go down Good job !

[@markusfuller]

Vegetto Blue I think its a real nice and yet aggressive filter at the same time. in a good way.

[@vegettoblue8705]

markusfuller Yves Is a legend for dropping this type of filter on Arturia s brute series instead of ladder one . I really like the sound of this synth , but as you said before you can t enjoy it via mobile s / pc s dac .

[@vegettoblue8705]

Mark also will be a dream To have one of this with the countinuous variabile slope 😊

[@Roderick_Legato]

This is what made me snap up a used MiniBrute from my local Guitar Center! I love the ladder filter, but this S/P filter got my attention right away!

[@ThomasGrillo]

Amazing! That little board did ALL That! Thanks for sharing this. :)

[@markusfuller]

ThomasGrillo Hi Thomas yes its amazing what can be done with a small simple-ish circuit when its been designed so well.

[@JakobHaq]

This is so awesome Markus. You're going to need to build another box again soon if you keep going like this. 😊 Btw, I used to spend weeks over at MFOS looking for stuff to build in the past.

[@markusfuller]

Jakob Haq Hi Jakob, yes i have been bitten with the bug, now i may just need to build another box soon.

[@freeelectron8261]

I like the way YU has added op amp buffer ccts to the original Moog ladder and some of the other units.

[@themadsamplist]

I really like the bandpass!

[@ZElTGElST]

I would love to hear FM from yourl oscillators. Some nice and easy circuits to build if you feel inclinated to: A Low Pass Gate (you can build an extremely easy pasive version just with a homemade vactrol, a pair of resistors and a cap). Another cool module would be a ring modulator. Whatever, I love this new "I build my modular" series. Keep on recording! ;)

[@markusfuller]

ZElTGElST yes do keep the requests coming in as I am not certain what to build next but I intend to just keep on going and work my way through as many circuits as i think i can manage. I think i may have to get another box made up soon though.

[@bartconinckx]

Great video again, Markus! Keep up the good work! You might also want to check vero wire wrapping, it is like wire wrapping, but without the special feet. You just heat up the special wire, solder it and have it replace the PCB paths.

[@markusfuller]

Bart Coninckx Hi Bart I use to do that years ago, need lots of patience to make it look nice.

[@bartconinckx]

it definitely does not look nice, it is geared towards prototyping

[@markusfuller]

Im sure vero wire wrapping would look nicer than my bulky second hand wire i'm using at the moment.

[@CaalamusTube]

The Arturia stuff uses this Filter ( more or less )... I think that nasty Resonance behavior is what people like about it. I've got a Mini & a Micro, but I've also got a Mother 32. I like that Moog Ladder *MUCH* better. However, with a setup as expansive as yours... I could certainly see a time & place for a bit of chaos! Thanks for sharing these inspiring Projects with us Mr. Fuller. Nice haircut by the by :]

[@markusfuller]

Caalamus I keep on toying with the mother 32. one day when I make a eurorack sized box I will have to think about getting the mother for sure.

[@CaalamusTube]

It's pretty "under the hood" ...but I'm *AMAZED* by how versatile it is! I uploaded a jam a few days ago where the Mother was acting as a self contained Drum Machine! You can easily get Sequences out of it with three distinct Voices√

Thanks. Very interesting!

[@markusfuller]

Manuel Rodríguez Fernández Thank you Manuel

[@robertsyrett1992]

Very nice! I love the handmade quality of these modules. Steiner-Parker filters are a little crazy for my tastes but it sounds great, and I've never seen all-pass on one before. Would you use all-pass mode for phasing?

[@MegaKid303]

Whoops I stand corrected I do apologise it’s oscillators that have to be vbe matched and the Steiner filter is hfe, sorry about that, as you Were

[@mrmrshoes1]

Hia Mark Can you do a video explaining your CNC machine for panel making. How hard was it to setup?

[@ScottFromCanada]

I'm curious about the level you are putting into the filter. In my eurorack modular I can put a very high level into a filter, higher than normal. In a few cases, like the Korg filter (most really) when I increase the signal level, it sort of overpowers the filter feedback, so the screaming resonance is diminished and you have a more punchy, thicker sound. I'm just wondering if you can do that to get a little more control over that feedback. It sounds much more pronounced than the filter in my Microbrute. And I find if you don't drive the Korg filter high enough it sounds kind of bad in that same way. Just too much screaming.

[@markusfuller]

Scott Rogers Hi Scott yes I spent hours changing resistors etc to try and find something manageable, I will certainly try and overdrive it to see what happens but i did that with the signal generator and it still squealed but it was so high the scope showed it but it was out of human hearing range.

[@ScottFromCanada]

Oh well, as long as the filter sounds different, it's still cool!

[@fordessexv6]

haircut!👌

[@markusfuller]

Stephen S better late than never. it was getting way out of control.

[@undoubt1540]

Hey Markus have you thought about using any of the MFOS modules. They sound really nice.

[@markusfuller]

Hi yes I have been looking at those and they seem pretty nice. Im not sure what to make next as im stuck at work just waiting for a day off so i can get back to making a video soon.

[@undoubt1540]

O.K. Cool man.

[@kossmonaut]

you should do a livestream where you make a bunch of sounds and music

[@markusfuller]

kossmonaut I really have tried to setup a live stream before but it all went wrong (its my age you know) . I will look into again for a future synth-club meeting and ask the guys what think about it.

[@markgreco1962]

What module should I start with??

[@LektroiD]

Which laser engraver are you using there?

[@markusfuller]

LektroiD Hi its the 20watt fiber laser marking machine . theres several different types but the all do basically the same thing.

[@MosheB87]

?can you do a AB compare between this one and the ladder please

[@markusfuller]

moshe banano well to be honest they are different filter types so the end results will be quite different.

[@MosheB87]

now that I think about it i can simply check it out myself on your videos. no need to trouble you with another ...Video thanks

[@MegaKid303]

You don’t test the transistors for hfe you test them for vbe there is a big difference for 1 volt per octave tracking therefor vbe is the most important distinction I just thought I’d clarify that as you can probably get away with it but it does say on ray Wilson’s site Ken’s site and with the Ian fritz’ site that it is importantly vbe not hfe a totally different thing.

[@markusfuller]

the navigator I know that already and I do several of the tests but rather than making a longer video about transistor testing i was using the hfe reading in the video just as an example that handling thransistors while under test will give different readings due to temperature changes.

[@klopfenpopmusic1126]

I was planning to get Yves's Moog filter clone kit, but I saw it was the 5U Moog format. How does Moog format level compare with line and Eurorack level?

[@markusfuller]

Klopfenpop music they both seem to work fine directly from the moog even though both the ladder and steiner are working on eurorack voltages.

[@MegaKid303]

If you look on yves site he makes a lot in 12volt and with motm dotcom and eurorack headers

[@MegaKid303]

It will behave better if you match vbe and the Steiner is known for being aggressive

[@klopfenpopmusic1126]

Yeah, I was interested in the Moog, one, though. I already have a Minibrute with his steiner in it.

[@MegaKid303]

if you look on yves site he says that he has a eororack header on the pcbs and if you read which ever one you want will give you any alterations if needed for the 12v as dotcom and motm run on 15v

[@MegaKid303]

The filter would behave better if you had matched the vbe

[@SouthpawShorts]

You could aways get some "proper" pcbs manufactured! it’s probably just as cheap as the veroboard you’re using, plus its way faster to populate and you can sell or give away the extras.

[@markusfuller]

SouthpawShorts Hi I can make the proper boards but i wanted to start this series of by using something that anyone can sort of have a go at building one at home without the complications of ordering a board from a manufacturer. I will gradually introduce ways to make boards like etching & cnc in future videos.

[@SouthpawShorts]

true good point! I suppose there are lots of places to learn about pcb layout, EAGLEcad etc; EEVblog is a good one, I’m sure you know it. I might give these filters a bash but for the eurorack format. Cheers!

[@Futschikatores]

The veroboard costs maybe 1€, the manufactured PCBs cost 10…15€ (don't forget shipping costs).

[@SouthpawShorts]

Allpcb and pcbway can do 10 pcbs for around $20 shipped! depending on the dimensions of course

[@Futschikatores]

So and how would that be anywhere near "just as cheap" as handmade PCB? He is building a single unit.

[@SamLowryDZ-015]

It's sounding very 70s Pertwee Dr Who .... which is not a bad thing.

[@ThomasShatter]

Just admit that you will end up building full modular from yusynth :D

[@markusfuller]

ThomasShatter I hope so. theres so much to choose from. thats 2 done but i dont know how many more to go before i need some more boxes and a bigger house.

[@Roderick_Legato]

Oh yeah - you're hooked :-)

[@chuckcrunch1]

even on AKG's the bass isínt obvious

[@WoodyPianoShack]

who's this bloke? can we have the normal host back please? :/

[@markusfuller]

who the one with more hair LOL

[@_Thorsten]

lol

[@MegaKid303]

Check out the legacy section of acxsynth.com for some diy Moog format modules, there is a really good midi 2 cv module as well as many others which are free to copy, Moog panels to. If you ever want a proper Moog panel just like the original check out a UK firm, Resythesis.shop for top quality panels, its where most of the pros go etc. Cheers Mark, I told you I will let you know when I remember stuff . Have you checked out Dave Browns wealth of knowledge yet, its right up your street. Modularsynthesis.com

[@cbmsysmobile]

I fear you just dated yourself by admitting to hoarding - i mean collecting components for 40 years :D Never throw anything away, you will only need it the day after....

[@markusfuller]

Alex Im already dated well before neil armstrong walked on the moon or england last won a world cup.

[@CaalamusTube]

Honestly you kinda surprise me with that one Mr. Fuller. I was thinking you might by 45! Have you been playing with Lightning that long!?

[@markusfuller]

Caalamus I think I first electrocuted myself when I was 6 years old and was instantly hooked for life :-)

[@sopalen]

Those numbers looks like hfe, that´s not the way to go, you should aim for Vbe done easy with a normal multimeter.

[@ewajustka]

adopt me please!!!!

[@ewajustka]

also, love your shirt!!!!!

[@crolodon8024]

I like your videos Markus but I'd like them even better if you mic'd your voice up more nicely. It's a little quiet and a little dull-sounding, not the tone of your voice but the quality of the recording, and it could sound much nicer.

[@Tron1731]

You need a Roland drum machine like a 505 to make some real analog tracks

[@_Thorsten]

505 is a digital Drummachine. It uses samples. An 808 maybe. Its fully analog. And a 909 is Analog for BD/SD/RS/Toms/Claps/Rimshot. Hihats and Cymbals are digital.

[@CaalamusTube]

I prefer that 606!

[@Tron1731]

Thorsten do you have one ?

[@Tron1731]

Analog midi controller?

[@CaalamusTube]

MIDI ≠ Analog MIDI stands for "Musical Instrument / *DIGITAL* Interface"
