Superbooth 19: GRP Synthesizer V22 Analog Vocoder First Look

At Superbooth 19, GRP Synthesizer announced the V22. It’s a full analog Vocoder with 22 bands that offers 22 bandpass filters, 1 LP, and 1HP analysis filter as well as an HP filter on the main output. The V22 is not a small compact vocoder but a huge one that can be installed in 5U systems.

I had the opportunity to check out this massive analog vocoder. Check out below my first look video with Enrico in Vocodish. 16

Overview

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 (please find all the details in the Upcoming Events section of this newsletter).

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 independent cabinet with wooden panels with an also an optional ‘Tolex’ version, these are the main technical features of the Grp Vocoder V22.
