The story

Inspired by Stockhausen’s Stimmung (for 6 vocalist), I generated ostinato vowel patterns, using Csound (see FOF Choir instrument) of 4 out of the 5 vowels a, e, i, o, u, (triplets 3) in 8 different rhythms ranging from 4 whole notes to 4 sixteenth notes. I used the Matrix (see also my Sansula Matrix instrument), to cluster these different rhythms in 3 notes.
These rhythms adapt to the tempo of your DAW. Every note has a different ostinato vowel pattern, one of the 120 possible permutations.
You can individually assign the different rhythms to each cluster of 3 notes, or use the randomize button (or red keyswitch) to get a random assignment. With the column select buttons (or yellow keyswitches) you can also assign the complete range to a rhythm.
The instrument is available in Kontakt 6 and in DecentSampler format (split into 9 instruments: random rhythm pattern, 8 rhythm patterns (4 whole notes – 4 sixteenth notes) as 60bpm loops)
Developed in CSound 6.15, Kontakt 6, DecentSampler

  • Fun inspiring retro choir

    I really like the FOF Choir instrument, but this takes it to a new level. This instrument is incredibly fun to play and experiment with, and when you get something cool out of it you can almost hear the rest of the arrangement building up around it. The matrix idea would be good for all kinds of sounds, but I think it's particularly well suited for the FOF Choir.

  • Instant fun

    Got inspirational sounds in seconds!!!!! Looking forward to playing with it even more. Loved the organy overtones at the top end. Instant rhythmic patterns. Brilliant. Even managed to get some Mongolian Throat Singing out of it. I don't have enough time in my life for this kind of fun!

  • Another choir library with Matrix!!

    And now boom! Another randomizable choir library! This is just amazing. In a few sec I got such an interesting textured voices. It is very fun to play with, very inspiring!

  • Beautiful Formant Electronic Choir

    These sounds are so brilliant. You have your own robotic choir with so many different variants with your formants. there are seemingly endless combinations to choose from! And the matrix is extremely intuitive and easy to use! The only downside to this is that it is a pretty distinct sound so it really won't fit in every setting though I think using it for sound design opens up some wonderful opportunities especially with a slower pitched down granular plugin on it. So excited to experiment with this!
