    In my day to day production work, I have my standard tool box of favorite EQs, Compressors, and VIs. Then there's my Secret Tool Box ... Vielklang is on top of that tool box.

    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.

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