In the spirit of sonic exploration and musical evolution we bring you the Grendel RA-99 Grenadier, an all-analog synthesizer with an original and unique tone palette. It implements parallel formant synthesis with a bank of three voltage controlled filters to generate tones inspired by the human voice, without being limited by the conventional boundaries of speech modeling. Twenty patch points give you extensive self-patching options plus creative compatibility with analog modulars, sequencers and keyboard controllers.
