GRP A4 – The 3rd Series

Well, it remains to be seen whether the GRP A4 is currently the best “non modular analog synthesizer” with an integrated sequencer – or not. Our opinion: Yes, it is! The high demand for this instrument speaks for itself. Even “Master” Jean Michel Jarre has bought one. The first 55 units were built in 2012. The second edition in 2013 was again composed of 55 units. The current third edition has started with a modest 35 pieces. Which has to do with the fact that GRP is presently involved in the development of new products – to be specific, we’re talking about the R24 stand-alone MIDI/CVgate sequencer.


So it remains for us to inform all those interested that a 3rd edition of the noble GRP A4 is currently being issued. The price is an – almost unchanged – € 3.777.– plus taxes and shipping (= in Europe: approx. 4490 Euros + shipping).

“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,, 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,, 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.
