Juergen Haible JH-3200 PolyKorg Clone (a one-off)

SOUNDFILES

  • Cosmetic condition: very good
  • Technical condition: very good
  • A one-off, made by Jurgen Haible in 2002/2003
  • The sale of the JH-3200 is not yet finalised, but since we have two PS-3100s with MIDI, it is at least ‘conceivable’. If you are interested, please let us know.
  • The JH-3200 is the perfect blend of PS-3100 (resonators) and PS-3200 (2 VCOs per voice, storability / pull-out potentiometers / 64 memories).
  • Beyond that, the JH-3200 is an instrument all its own. It has an additional (global) HighPass filter, and instead of the Korg chorus, Juergen Haible opted for the more beautiful ARP OMNI 2 chorus, which is continuously adjustable in two levels.
  • The sound is – to our ears – softer than the original character of the Korg PS series, with a marvellous character in stereo (direct out, main output), extremely lively and warm.
  • Of course, it can do much more than the pad sounds in the two sound samples, but the pads are particularly nice …
  • Precise manufacturing, high-quality hardware, weight: 30 kg
  • Full polyphony with 49 notes (C to C), MIDI connection
  • All documentation/circuit diagrams available

    Price: On request.

“Es genügt, einen Ton schön zu spielen” sagte der Komponist Arvo Pärt im Jahre 2005. Diese Aussage ist ebenso einfach wie ich auch exzellent: Es braucht kein Meer an Tönen, denn entscheidend ist der Klang. Dass so mancher Vintage-Synthesizer der 70er und 80er Jahre teils unerreicht hochwertige Klänge liefert, steht außer Frage. Doch tatsächlich leben wir “heute” in einer nahezu perfekten Zeit. Einerseits hat man – mehr oder weniger – noch Zugriff auf die Vintage Analogen, andererseits wird auch bei Neugeräten die wichtige Komponente des hochwertigen Klanges wieder zunehmend berücksichtigt. Doepfer, Cwejman, Synthesizers.com, MacBeth, Moog, GRP, Studio Electronics, COTK, John Bowen und andere Hersteller bauen hervorragende Synthesizer, die den “Klassikern” in nichts nachstehen. All diesen (alten wie neuen) “großartigen” Instrumenten ist Great Synthesizers gewidmet. _________________________________________________________ In 2005 composer Arvo Pärt said: “Playing one tone really well is enough”. In other words, it is sufficient to play one tone 'beautifully'. I agree with that. All musical efforts are focused on the sound itself. Although I studied classical music (piano and drums), it’s the electronic sound that inspires me. Synthesizers are the epitome of new sounds and exciting tonal spheres. Today, many companies produce high-quality - excellent! - synthesizers: Doepfer, Cwejman, MacBeth, Moog, GRP, Synthesizers.com, COTK, Studio Electronics, John Bowen and others. It's their products I'm really interested in ... apart from Vintage Synthesizers, which I have been collecting for 20 years. Subsequent to our former websites Bluesynths and Blogasys, Peter Mahr and I have now created GreatSynthesizers. We hope you like it.
