Wutierson Custom KORG Replacement Chips for 700, 700S & 800DV

via Toni Gutiérrez Ortiz on Facebook

"Good news for all owners and fans of the first Korg synthesizers : 700, 700S and 800DV!"

"Now available replacements for Korg custom chips! http://wutierson.com/en/news/115-keio-replacements Good news for all owners and fans of the first Korg synthesizers : 700, 700S and 800DV! Now available in the store Wutierson replacements for Korg Keio IC TS200011 for the VCO and Keio IC TS201012 for VCF. Inside the old synthesizers we can find a pair of sealed modules at the VCO core and at the VCF "Traveler " which were manufactured by Korg exclusively for those models. The problem came years later when for some reason a module failed and could not get the same part , unless destroying other synthesizer that uses it. Colin Fraser in 2010 did a great job making reverse engineering of each module , so at least, you could start to make a replacement with the right components, to avoid "sacrifice" of other old Korg synthesizers. Colin's work has been a big help to start making these replacement modules . We recommend to visit his website to learn more about their interesting work . http://www.colinfraser.com/ Now it will be much easier to repair one of those lovely synthesizers. Using Wutierson replacements you can avoid spend time with design/making dedicated PCB , avoid spend time looking for the parts, avoid spend time with select/match components to ensure an exact performance like the old IC's. The replacements are ready to install, just unsolder the defect old IC, put and solder the new replacement and continue playing! saving much time in the repair work."

Update: vide re-Published on Apr 25, 2013 - new video below.

"First part of the elkorus v3 video processing guitar, traveling around the different sounds that can be obtained since lush tri-chorus to depth tru-zero flangers. The sounds are usually just guitar-elkorus-amp, but in some cases we add phaser or delay."

The elkorus is by Synthoma. via this post: "The élkorus is a chorus unit that emulates the classical "ensemble" sound of those string machines from seventies. That emulation is not achieved by any DSP technology or software. The élkorus sounds analog because is really analog."

"First part of the élkorus v3 session processing guitar. Now it's time to process a clean guitar. The sound path is guitar-elkorus-amp but we add delay or phaser in some moments.
In this demo we can travel around lush tri chorus, tru-zero flangers, vibratos, or kind of comb filter sound, all with 70's and 80's vintage feeling.The CV features allow to any guitarrist to tweak all the LFO's parameters via CV foot pedal. For more info just visit:

Logan string melody meets the elkorus

Published on Sep 27, 2012 by wutierson

"This day, the Logan string machine visits Wutierson studio and it's imposible to don't do experiments with an elkorus.
The different types of chorus available at the Logan are very useful. It makes more versatile to process.
Tweaking the elkorus parameters + the Logan chorus I can make even more deep and lush chorus... ensemble of ensemble! a six line chorus! : )
No more effects are present, it's just Logan + elkorus v3"

The String Machine project

"The String Machine project

Now that a ensemble chorus processor like the élkorus v3 is available I can announce the beginning of the 'String Machine project' at the Wutierson site. Since some time I have the idea of collecting basic waveform audio samples of different string machines with chorus turned off, to sample it and obtain a precise emulation using an elkorus.

http://www.wutierson.com/en/news/101-string-machine-project

More sounds will be available very soon! Stay connected!"

Currently you'll find samples of the Logan String Melody, Roland VP330, and Solina String Ensemble.

Antonus 2600 Videos by wutierson

Published on Jul 28, 2018 wutierson

"During some test magic happens when the great musician Francisco Nicosia (from Klauss band) was playing the Antonus 2600 , Antonus Step Brother. In one moment Fran was playing Oxygene 1 (Jean Michel Jarre) and decide to record it.
The 2600 created the bass-timpani sound with the Electro Hamonix Small Tone phaser and is controlled by midi using the Dave Smith Poly evolver. At same time 2600 is making high pitch FX with help of the Step Brother.
For the strings Clavia Nord Stage with custom Eminent patch was used.
Only simple delay was used and Antonus 2600 analog spring reverb was used. No more FX or EQs or Compression.
Thanks to La Siesta del Fauno studio in Buenos Aires for the moment."

ARP2600 clone TTSH first test with Ernesto Romeo from Klauss

Published on Jun 3, 2014 wutierson·27 videos

"First Wutierson TTSH unit, ARP2600 clone. Designed the remake of the original cabinet tolex to suit the synth because the original ARP2600 is a bit bigger.
This is the first burning test of the first finished unit. After a few calibrations the units can show their genuine sound, the spirit of the ARP2600 grey face is here! Very happy to see that this clone can do the ARP2600 job very well. ,
No external sound processing, the sound is just what comes from the synth. The reverb process is from the built-in spring reverb system.
Sorry for some hard clipping of the sound card, specially at the begining of the video, the 2600 have a lot of dynamic range and take a suprise when Ernesto Romeo did the first patch so I try during the recording with one hand stay filming and with the other adjusting the input fader of the mixer, to avoid hard clipping."

Korg PS-3300 + Antonus 2600 Original Size live jam demo improvisation "Pompidou in Tokyo"

video upload by wutierson

"Korg PS-3300 + Antonus 2600 Original Size live jam demo improvisation 'Pompidou in Tokyo' by Toni Gutierrez

Here is the third video of a series with the wonderfully enormous (in all aspects) Korg PS-3300 playing with Antonus instruments. This Korg PS-3300 was in Antonus studio and workshop during some months for study, works and of course for enjoy it playing.

This third video is an improvisation using Korg PS-3300 with the Antonus 2600 Original Size model. Connected both instruments with so many patching points for make this abstract and experimental track, looking also for the west coast essence that can be found in the 2600 design. The 2600 is a wonderful design were we can find good examples of the east and west coast schools.

Is very interesting to play with the polyphonic concept of the PS-3300 and at the same time work with structural part and auto generative patterns. I will to continue to make more experiments in that way, is a very unique instrument!

Also the wonderful design of the 2600 allows to make a very fast performance, so faster than the 3300 due to the slider design and how are placed... offering the the feeling of hand moulding sense, like sculpturing with hand, that allows to the performer to feel that is one more element of the system interacting with all parts.

The demo is recorded in one take, no multitrack was used in this recording. Only Korg PS-3300 + Antonus Step Brother + Korg SDD1200 dual delay unit.

Unlike the other two previous tracks this is very abstract. For people that doesn't like this kind of music I recommend to check the other PS-3300 videos with more melodic content.

Thanks to Ernesto Romeo from La Siesta del Fauno studio laboratory in Buenos Aires for bring us for a time this awesome piece of electronic music history."

Playing Yamaha CS-80 with elkorus and other chorus units

"Test session with Sergio Koval playing his Yamaha CS-80 at Synthoma studio. The test is a chorus comparison with the CS-80 built-in chorus, a Digitech multieffect chorus, and the élkorus analog bbd chorus. Now the CS-80 can do a very nice strings, not only brasses!!

Antonus 2600 + Step Brother + Black Corporation ISE NIN demo jam

video upload by wutierson

"Here is a demo jam using Antonus 2600 Original Size version, with Step Brother on top and the Black Corporation ISE-NIN. All the track is done in realtime, no multitrack recording. Antonus 2600 and Step Brother is making the different sequencer sounds, the bass drum, and the hihat sound plus some other sound during the perfomance. ISE-NIN (played with midi keyboard controller) is playing two sound using the Upper and Lower layer features like the Roland Jupiter 8, one layer is for the string-pad sound and the other layer is for the arppegio-sequence-effects during the performance. Is not easy for a poly synth to play face to face without being surpassed with a synth like a 2600 and the power of the ISE-NIN makes a very good partner in sound presence and quality with the 2600 and Step Brother. I know that the demos should be short and direct but every time that I play instruments like this the time goes fast and simply at the end I don't care nothing more than enjoy playing, so I'm sorry of the demo is too long or if nobody will listen it or just make jumps during transport bar. This instruments are a true joy of play and this is the result of it. Hope somebody enjoy the sounds and can have a better idea of the nice combo that are.
Also booth instruments shares a nice orange colour details, lovely combination!"

Korg MS20 farewell, LM13700 filter + VCO1 PWM and VCO2 Hardsync mods

Published on Aug 19, 2014 wutierson

"Farewell time, my beloved classic Korg MS20 will leave my studio. The new owner will enjoy it a lot.
This unit is modified with VCO1 PWM modulation via patch panel, using the trigger button output. The Trig button is replaced with at simple switch to allow VCO2 hard sync.
The sonic possibilities expanded a lot with only this 2 mods. The best of that is the unit is not drilled, the modifications can be removed, and the unit can be in the original state again.
The video has not any particular musical intention, it's only a resume of my last farewell playing with the MS20, to remember the sound and character with the mods. At the begining, it's hard not to play 'Being Boiled' when the MS20 is modded with the PWM input. I don't play any Korg35 filter version but to my ears the LM13700 sounds very good, specially how the two filters interact one vs other with the resonance at high levels. I don't know if the Korg35 filter have this character.
Not external sequencers or addtional sound sources are present (the rhythm effects and echo sounds are done with the MS20 own possibilities), it's just only the MS-20 sound playing in real time with only a bit touch of reverb. No more external processing, no EQ, compression... etc. Just that."

MOE Chorus 60 with Antonus 2600 Original Size part 1

video upload by wutierson

"First part of a serie of videos showing the wonderful sound and different creative uses of the Mother On Earth Chorus 60, by far the best Juno 6/60 chorus clone in pedal format, using exactly the same components and circuitry and also adding some nice extra features and controls.

Making an awesome combo with the Antonus 2600 Original Size, replica of the ARP2600. Very noticeable how nice works this chorus with synthesizers. Is no easy to find pedals that sounds good on synthesizers rather than only in guitars and this pedal sound so nice in all terrains. It makes the lush chorus sound and at same time it works with all the complex harmonic content of the synthesizer sound with more low range frequencies, different than the other more specific guitar oriented pedals. Also it preserves the quick transient and dynamics very good considering the nature of this kind of effects and preserves the low end and high frequency definition. Also very good balance between dry and wet signals levels.

This recording is done using without extra process and sound make up, only just the sound of the 2600 and the Chorus 60.

In this first video we focus in more regular chorus uses, from the classic Juno ranges to different levels of modulation amount and speed using the controls and from time to time switching from processed to dry signals (notice the red colour at the pedal switch when effect is OFF and blue when effect is ON)

In other videos we will show the nice feature of the external CV control and feedback loop techniques.

Both Antonus and MOE are handcraft companies making high grade products with care and love. Antonus working in Barcelona and Mother on Earth working in Israel.

Both brands products are available for distribution at www.enlo-1.com shop, making easy for EU customer to purchase the MOE Chorus 60."

Antonus 2600 Building Timelapse

Published on Jan 25, 2020 wutierson

"Timelapse of Antonus 2600 cabinet building process and final assembly. Many hours of work condensed in this video! The soundtrack is made using Antonus 2600 and Antonus Step Brother, multitrack and recorded in 6 takes.

Every Antonus 2600 have its cabinet made like the classic ARP 2600 using wood, Tolex and hardware using our hands. Every unit is made with people who works with care and love, like instruments was done in old times.
In Antonus we believe that this energy and intention is part of the the original instrument and we want to do in that way, maybe is not the easier or cheaper way but is the most sincere with the original spirit, more human feeling and less mass production / automated production."

élkorus output features - autopanner with élkorus

YouTube via wutierson | October 10, 2010

"Élkorus v.2

Among other improvements this second version includes three modulation outputs corresponding to each BBD (audio delay chip) modulation phase, which means:
LFO1+2 at 0º modulation phase
LFO1+2 at 120º modulation phase
LFO1+2 at 240º modulation phase

This video suggest just one use for those modulation outputs, like to modulate a three VCA's bank panned 1 to 50% left and right, 2 to 100% right and 3 to 100% left in order to obtain an auto-panner effect.
The sound source is the Roland JX-8P processed througt the élkorus at the
same time.

Gear used:
-élkorus v.2 (modulator and processor at same time)
-modular analog synthesizer with dotcom, stg and cotk modules (VCA's)
-Roland jx-8p (sound source)"
