DigiTech Studio Vocalist - of Daft Punk fame

Super cool vocal tuning, harmonizer, midi style vocoder. Has built in microphone preamp with 48v phantom power and insert points for external gear.

Line inputs allow you to use your own preamp or line level gear, use as a writing tool, use during mixing. Works amazing with mono synth and other mono sources as well.

Algorithms were designed by ivl technologies and if you don’t know who they are you’re not the only one. They designed in my and many others opinion the coolest sounding harmony processing ever and you’re looking at it.
