"Grp Vintage Genesi is a synthesiser that traces the sonic legacy of a design that was very popular in the early 1970s. Designed faithfully to the original specifications, Genesi is a true tribute by Grp Synthesizer and its founder Paolo Groppioni to the sounds of one of his main reference bands, as the name of this synthesiser in this new Grp Vintage series clearly indicates. The sonic characteristics of the original are identical in all respects, but this instrument is able to offer the total reliability and performance guaranteed by the latest components and technology implemented, all at a price that is certainly more affordable than the original editions of this historic synthesizer model."

via this Reverb listing

"The GRP Genesi is a small-batch faithful hardware recreation of the ARP Pro Soloist in rack form from Italy's GRP - who also made the exceedingly excellent premium-grade GRP A4 analog synth, the A2, and so on.

The Genesi is a preset synth using analog circuits with various settings easily assignable to aftertouch. There are great switches and knobs but it is entirely free of menus. The manual is available online, it is extremely easy to use.

The video attached from GRP is from the prelease.

This synthesizer is Serial Number 5 and has seen only home smoke-free studio use. It has no rack rash, and will ship professionally packed and fully insured."

"The A4 is an incredibly powerful mono synth that sounds divine. Has incredibly versatile and in depth amount modulation capabilities and sonic potential.

I'd recommend looking at the online specs to get a full run down of this but it has two multimode filters, 3x gorgeous sounding VCOs with 1 and 2 having sub VCOs, A unique 16 step sequencer, two LFOs, a sample and hold module, and the list goes on."
