"...Vielklang is undoubtedly musically powerful and sophisticated, and as ever, a little musical knowledge will help you get the best out of the program. However, I have to say that it’s pretty easy to operate straight out of the box. Beginners will have great fun hearing their lead vocals transformed into a harmony-singing group (especially one that sings all the right parts without rehearsal and doesn’t require payment). Since it doesn’t work in real time, it’s not the right program for gigging solo vocalists looking to create live harmonies, but it’s an ideal studio tool. Whether you need a barbershop quartet, Everly Brothers-style harmonies, an experimental classical vocal arrangement or some cool voice parts for your R&B track, give Vielklang a whirl and bring a little harmony into your life!.." – Sound On Sound magazine (UK) December 2008:

Vielklang audio harmonization instrument from z.plane development is a versatile intelligent harmony generator for musicians, songwriters and producers. It creates backing vocals and brass sections with up to four voices in a more musical way than traditional harmony processors. vielklang utilizes sophisticated voice-leading and harmony progression models to generate more natural and musical arrangements rather than producing plain parallel voicings. The piano-roll display allows complete control over every pitch of every voice.

It's all about Music

Vielklang "thinks musically" and prepares intelligent voicings. vielklang by zplane is packed with musical intelligence and music theory: it automatically 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 automatically selected to sound most natural (voice leading). vielklang gives you a natural-sounding result immediately and allows you to concentrate on tweaking the results rather than edit them from scratch as with traditional harmonizers.

Creativity First

Directly interact with the music rather than with the technology. Don't waste time with tedious configuration of obvious parameters like root note, scale, tuning frequency etc.; let vielklang take care of this with its automatic recognition engines and concentrate on making music! Have complete control over your voicings and musical parameters like harmonies, pitch range and scale.

Discover the Potential

The vielklang audio harmonization instrument is not a harmonizer, but much more! With the vielklang plugin, you can easily generate and trial natural sounding background vocals and brass sections, modify melodies and single-voiced loops in terms of pitch and scale, and experiment with different harmonizations or chords triggered by different MIDI inputs. It allows you to generate up to four voices, edit their harmonies and single pitches, control the playback speed, and convert the audio to MIDI.
