GRP Redesigns Website Including Details on New Eurorack Modules


This one is in via John L Rice. GRP has a new website! Their new site includes details on their latest eurorack modules announced at this year's Superbooth. The following is a quick capture of the individual modules for the archives.

"The Grp Synthesizer products are completely hand-assembled and are the link between technology and handcraft, worthy heirs of lute players translated into modern technology. It is important for us to keep constant, in the long run, the sound and designs characteristics so to render unique the Grp Synthesizer and to maintain high quality, also for the future entry level models. The Firm philosophy aims at projecting this engagements in the business so as to guarantee the maximum satisfaction to the client."
