CV Toolkit is a software that lets you many different virtual modules to control, modulate and sequence your synthesizers via control voltage (CV). These virtual modules can work independently or can bet set to influence and modulate each other via the Routing Matrix.
With CV Toolkit 2, you can create anything from multi-channel rhythmic sequences to complete polyphonic patches.

In order you CV Toolkit with your synth, you'll need a DC-coupled audio interface or an Expert Sleeper's ES-3, ES-4, ES-40, ESX-4CV, and ESX-8CV modules*.

The new 2.0 version was to design to be both easy for beginners and extremely flexible for more advanced users. We want the users to feel comfortable while taking their first steps with the program but also have enough different tools to help to go further and deeper as they get more familiar with CV Toolkit.
