GRP R24 Sequencer – pre-orders now opened!


The GRP R24 is a 8×3 analog step sequencer firmly based on the mighty sequencer of the GRP A8 and GRP A4 analog synthesizer. The new R24 offers access to “both worlds”, it comes with CV/Gate, USB and MIDI! Hardware-wise, it is a self-powered stand-alone unit, with hardware compatibility for mounting the R24 in a 5U modular system. That means you can use it either as-is (with its case and internal PSU), or you can install the R24 in a, COTK, Moon Modular system (and use the empty case for other 5U modules).GRP-R24-Sequencer-10

The R24 can memorize 64 sequences! Each sequence can be set to 8×3, 16+8 or 24 mode, with individual step lenghts. In addition, there’s an independent sample&hold circuit per row! The sequencer acts as CV/Gate sequencer or as MIDI sequencer, with separate rows for MIDI Note selection and Key Velocity step adjust.

“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.
