    Vielklang is the most simple and efficient harmonizer I have used so far, congratulations, guys.

    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.

    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.

Instant Harmony & Advanced Pitch Editing

vielklang Instant Harmony generates harmonies with 2-4 voices. It is packed with musical intelligence and music theory: it detects the best fitting harmonies for each individual input melody, and automatically synthesizes up to four voices with the voices not merely running in parallel but with their voicings selected to sound most natural (voice leading).

The advanced pitch editing controls (full version only!) give you fast and easy access to pitch, timing, vibrato control, formant shift, and to many more editing options.
