vielklang is a plug-in instrument for instant audio harmonization. vielklang generates up to four voices from a single-voiced audio input. The progression of each individual voice is controlled by sophisticated harmony progression and voice leading models, resulting in musically meaningful harmonization without any configuration effort.

With vielklang musicians can easily generate and prototype natural-sounding background vocals and brass sections, modify melodies and single-voiced loops in terms of pitch and scale, and experiment with various harmonizations or chords triggered by different MIDI-inputs. It allows the user to synthesize up to four voices, edit harmonies and single pitches, and convert audio to MIDI.

The four voices don't simply move in parallel, their individual progression is controlled by a complete set of voice leading rules and sophisticated harmony progression models. This musical intelligence and knowledge lets the user focus entirely on musical issues, rather than technical or theoretical ones. vielklang helps to achieve musically meaningful results without having to bother about root note, scale, tuning frequency, harmony progression and voice leading.

While vielklang provides instant and meaningful results, experienced users also have the option of changing harmonization parameters like the range (ambitus) or distribution of the voices, modifying root note and scale, editing single harmonies and changing individual pitches in each of the voices.

Main features:

  • Instant 4-voice harmonization of any single-voiced audio input.
  • Integrated voice leading and harmony progression models, resulting in entirely natural-sounding automatic harmonization.
  • One-click modification of key scales and harmonies.
  • High quality, formant preserving, flexible pitch shifting.
  • Audio-to-MIDI functionality for all voices.
  • Customizable user interface.

Vielklang has changed my song writing process forever! I bought it hoping it would help me create an occasional harmony or two. Wow! I got so much more than a simple harmonizer. This plugin instrument is like having your very own musical harmony/theory genius buddy at your side, who is never too busy! I don't know how it works, but it seems to carefully analyze whatever melody you feed it and then quickly revealing several harmony options to choose from. I have many tunes in my head and like to get them out as quickly as possible. I'm not a musical theorist, and before using Vielklang I struggled with the harmony part of my productions. Figuring out the scale, root note, progression, etc would bog down my creativity and often the original inspiration would be lost. With Vielklang I can now focus on finishing songs, and they sound much better.

I have also used Vielklang in the classroom as a teaching tool for ESL students, learning disabled, and young adults with speech difficulties. I have found that creating and reciting harmonies is an effective tool in smoothening out vocal/speech patterns and helps with intonation and elocution. .. and it's fun to use. It breathes life into my lessons.

Creating harmonies used to be like jogging in bad shoes, and now it's like playing my favorite sport on steroids! I should mention that the interface is a pleasure to work with. .. so clean and clear. I'm a visual person and seeing the notes is pleasure. Hey, the price is good too. I have paid ten times as much bribing music theory gurus to help me create a harmony or two. zPlane has developed a fantastic plugin instrument that can provide creative options and enhance anything that has notes. I will keep it and update it as long as I have a melody in my noodle and someone nearby with at least one ear! Thank you zPlane.
