INTRODUCTION

The VVCA is a fully analog dual voltage
controlled amplifier (VCA). The unique part
of this VCA is the velocity input, which
makes it possible to modulate the
incoming CV signal with a velocity voltage
(or any other CV source). The VVCA is a
linear dual VCA and can be used for both
CV and audio signals. It is a straightforward
4HP module that adds velocity, and a whole
new dimension to your modular setup!
