V22 Vocoder
2019
The GRP V22 is a fully analog 22-band vocoder billed as 'the ultimate vocoder,' designed by Paolo Groppioni. It uses 20 bandpass filters (48 dB/oct, from 220 Hz to 5920 Hz) plus dedicated lowpass and highpass bands, each with envelope-follower output, VCA and individual level for band mixing. It includes a voiced/unvoiced detector on a combo XLR/TRS external input and an internal carrier VCO (saw and pulse) with CV and MIDI control; it runs standalone or in an 8U-wide 5U modular slot.
