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 …
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.
Paolo Groppioni and Enrico Cosimi couldn’t resist using the already completed A4 synths for a brief classical performance.
Patterning their presentation after Wendy Carlos with her then-new Moog system, eight GRP A4 were linked and operated simultaneously to perform the first movement of a Brandenburg Concerto by J. S. Bach. Without a doubt a unique idea, even if the results wouldn’t meet up to our present-day sound standards.
