The KM3VC is a software application that allows you to control your Korg M3 via an on-screen (virtual) controller!

Simply buy the KM3VC software, activate and start up the virtual controller and effortlessly control your Korg M3 from your desktop/laptop.

Who needs KM3VC?

Ultimate Virtual Control

Designed for Korg M3 owners who love their hardware but want the modern convenience of controlling every aspect of their sound from the comfort of their studio chair.

Touch Screen Issues

Many M3 owners have experienced the dreaded touch screen failure. Replacing the screen is a complex, risky, and expensive process. Fret no more. The M3 Virtual Controller software gives you full control of almost every parameter right from your computer.

Sticky Buttons

Sticky or unresponsive buttons can make simple parameter changes a struggle. Instead of battling with aging hardware, the KM3VC software allows you to navigate and edit your M3 sounds with ease, without having to press a single physical button.

Abandoned Software

We all loved the original editor! But as operating systems evolved, it was left behind. Let’s rewind the clock and bring new life to this legendary workstation with a modern software solution built for today’s studio environments.

No more sysex!

What about those pesky bank/program changes, not to mention the dreaded sysex messages… we have handled all of those technicalities so that you can simply click and touch your way through the virtual M3 interface, and your hardware will obey your every command.
