    Vielklang is the audio toolbox that I'd hoped the other harmony generating plugins would be. The ability to edit and export MIDI is huge. Additionally, I'm so impressed by how intelligent Vielklang is at recognizing exactly what melodic content is input. It is an indispensable production tool for me.

    PPMulator+ is an invaluable tool for people working in the world of media music. If you're mixing or mastering for broadcast then you need this plugin!

    The quality of "ELASTIQUE PITCH" is amazing. It´s the best real time pitch shifting (incl. formant shifting!) solution in my ears - and really easy to it !

    I absolutely love the PPMulator suite of meters... PPMulator gives you the data you have somehow always wanted, but couldn't have – until now!

Product Registration and Unlocking

How does the unlocking process work?
Our products are delivered with a unique serial number. After registering your product you will receive an unlock key. You need to enter both, the serial number and the unlock key into your software.
How do I register my software?

How do I use my upgrade serial number?
