GRP A4 – Series 2015

Paolo Groppioni never dreamed that his GRP A4 synthesizer would be such a success. The synth is now in its 4th edition. To be honest, that doesn’t mean that thousands and thousands have been sold: really, truly, less than 150 GRP A4 have been built up to now. Handcrafted thru and thru, of course …

GRP-A3-01

Despite strong competition on the lively market, the GRP concept remains singular (as it will in the future).

The synth has, as we all know, 3 VCOs, 2 sub-oscillators, 2 VCFs, ring-modulation, cross-modulation, S/H, 2 loopable envelopes, 2 LFOs (and much much more, including a tricky 2×8 step sequencer).

The BEAUTIFUL and UNUSUAL remains the comprehensive, pre-wired modulation matrix. That sets the GRP A4 apart!

Need to route VCO 3 to VCF 1 frequency? No problem, just turn a knob and specify the exact amount of modulation. Need to route sequencer track A to LFO 1 speed? No problem, just turn a knob and … well, you get it!

GRP-A4-Series2015-03

Or … you need to synchronize Sample/Hold with LFO 1, the sequencer and auto-pan? Flip a couple of switches and that’s it …

In addition to this myriad of modulation possibilities, you also have precise dynamic controllability via MIDI at your fingertips. Exclusive ranges of expression, subtle sophistication.

GRP-A4-Series2015-02

Velocity, aftertouch and MIDI Clock can be routed to many of the instrument’s parameters. Given, of course, that you do know how to play a keyboard (or, at least, how to program a software sequencer to get that dynamic control you’re aiming at).

As the cream-with-cherry-topping on the huge amount of information you already have about this instrument, we offer you our GRP A4 test report. Lots of synth details, lots of soundfiles … read about, think about …

GRP-A4-Series2015-06

“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.
