DIY – Synthesizer DIY – Modifikation

Besuch beim FabLab Berlin

Dies ist der wirkliche Nerd-Platz in Berlin.
Man kann hier 3D Drucker, Platinenwerkzeuge, Holzbearbeitung, Metallbearbeitung, sogar Carbon-Werkstoffe bearbeiten, Prototyping machen und sich Dinge einfallen lassen. Es gibt kompetente Leute und Mate.

Ich bin mal durch gelaufen und habe mit Leuten gesprochen. Entwicklung von Synthesizern ist hier faktisch wie “Zuhause”. Hier werden wir vielleicht noch mal was zusammen machen. Eintritt ist übrigens frei.

Das Titelbild könnte der Schauplatz sein, wo Blixa Bargeld Hornbach liest..

Projects

  • QuadLFO – HöllLFO (gesprochen hell-eff ohh) – (hellLFO speak: hell eff oh) 4-fach LFO für modulare Systeme oder “Standalone” ein neues projekt.. by thomas & moogulator
    höllfo LFO modular
  • inzwischen kein DIY projekt mehr / no longer DIY – commercially sold till 2008 later..
    SemTex
    Oberheim SEM Extended.. Analoges Synthesizer Projekt.
    alter link/ old link: SEMtex S und XL- davor USM – Universal Synthesizer Modul(e)..das vom Oberheim SEM inspirierte Synthesizer Modul..
    new link / neuer link: SEMtex
    aber mit 2 Suboszillatoren, Ringmodulation einigen Extras..
    Ziel: Soll mindestens so gut wie das SEM klingen, tuts auch..
    The SEMtex is our SEM but with 2 SubOscs and Ringmod and some more..

    there has been the
    Böhm Soundlab by Professor Enders (University of Cologne, now Osnabrück).
    About Prof. Enders: http://www.musik.uni-osnabrueck.de/lehrende/enders/
    THE BOEHM SOUNDLAB .. short info..
    it uses banana jacks and is quite interesting / flexible.
    it provided multi mode filters when HPF,LPF,BPF combinations were still rare.
    böhm is a german electronic organ company for DIY kits and other stuffs from minden in germany. biggest competitor is wersi ;)

    find a nice info about the soundlab in “Synthesizer von Gestern Vol.2” by M.Becker who also released 3 CDs feat. Vintage Synthesizer Tracks ..

    the böhm was the only synthesizer by böhm beside the böhm dynamic expander with casio-type of PD synthesis , in this case phase modulation meaning phase distortion ;)

    the soundlab is quite rare and BOEHM offered DIY Kits and assemlbled ones.

    quite interesting modules were made..

    Matrix 6 & 6R /// Matrix 1000
    Both Matrix use six CEM3396 ‘Synth on a Chip’, M6 has wide body version (600mils), M1000 the small (300mils) one. Both Matrix synths have DCOs. Master clock is derived from a quartz on the Matrix 1000 and from three free running, software calibrated (voltage controlled) oscillators on the Matrix 6.
    M6 has a 4 to 2 split mode, the M1000 lacks this hardware, otherwise the voices are (nearly) the same.
    6 CEM3396 Dual Wave Processor (Wide body?)
    old definitiion: Matrix 6 and Matrix 1000 differed in the way that the M6 had a couple of Curtis chips to generate a voice while the M1000 used a “synth-in-a-box” chip from Curtis that had the whole voice in one IC. Even the “Wave” selection feature was packed in there. I only don’t know if Curtis developed this chip because Oberheim wanted them to do so. So, if someone wants to build his own analog synth, he might start with that chip. It’s not the best sounding chip but very easy to build control circuitries around it. On the web, you might find interesting information about SSM and CEM chips.
    (D) Beide Matrix verwenden sechs CEM3396 ‘Synth on a Chip’, der Matrix 6 im breiten, der Matrix 1000 im schmalen Gehäuse. Beide Matrixe haben DCOs. Der ‘Masterclock’ beim Matrix 1000 kommt aus einem Quarz, beim Matrix 6 werden drei softwareabgleichbare (spannungsgesteuerte) freilaufende Masteroszilatoren verwendet. Der Matrix 6 kennt einen 4 zu 2 Split-Mode, dem 1000er fehlt die Hardware dafür, ansonsten sind die Stimmschaltungen (fast) gleich.

    Filter? Curtis? Roland? Thats a common mistake. But there is NO CEM filters in any of the MKS revisions. The CEM rev. has only CEM VCO and VCA
    even the ju8 has no curtis filters.. same for the ju6..
    Both revisions uses 2 CEM3360 DUAL VCA per voiceboard for Crossmodulation-
    The older revision usesr IR309 filter like in JP4, JP8, Juno60 etc.
    The newer MKS uses IR305 which is both VCF and VCA. like in Juno1/2, JX-10 etc.
    So it is right as follows (I will remove the wrong ones soon):
    MKS-80 (racked jupiter8)
    MKS80 used 8 x IR3RO5
    ..to Serial <#511800
    WRONG (called the curtis / roland myth:):
    8 CEM3340 VCO
    4 CEM3360 DUal VCA
    Should be:
    16 CEM3340 VCO
    8 CEM3360 Dual VCA
    12 IR-3R09 VCF
    MKS80 serial >511800
    WRONG (called the curtis / roland myth:):
    MKS-80 Serial #511800 up (later models)
    8 IR-3R03 Roland VCO
    4 CEM3360 Dual VCA
    4 IR-3R05 Roland VCF/VCA
    Should be:
    16 IR-3R03 Roland VCO
    4 CEM3360 Dual VCA
    8 IR-3R05 VCF/VCA

    The JX8P / JX10 used a Roland custom filter

    MKS70 (racked JX10 / double jx8p)
    used 12 x IR3R05 vcf/vca never CEMs

    the revision was app. at the same time as waldorf changed to the
    Nextel-Housing
    –> “old” eloxiertes Gehäuse (housing) = 3389 – Nextel-Gehäuse (housing) = 3387
    it’s know exactly know if there are also a small amount of old/new CEMs in the vice versa housings, but it is most likely the same date.. ;)
