New GRP V22 VOCODER Revealed



A front panel drawing first went up here. We now have an image of the actual unit, and some details on the new GRP V22 VOCODER:

"After a sneak preview in Florence at Meff, we are working hard to be ready for the official presentation of the V22 at Superbooth 2019 in Berlin. Before Superbooth, another preview in Rome May 4th at Synth Day & Night with Mr. Enrico Cosimi.

A 22 band full analog design vocoder, with analysis and synthesis section full analog (20 BP, 1 LP and 1 HP analysis filters), a dedicated High Pass Filter on Main Output, everything hosted in an indipendent cabinet with wooden panels with a also an optional 'Tolex' version, these are the main technical features of the Grp Vocoder V22.

The preorder for the Grp Vocoder V22 is planned in June 2019; we are not able currently to estimate the price of the Vocoder, but as soon as the second prototype will be finished we will publish an updated pricelist.
