Here is a continuation of an earlier video showing how to create an all-analogue Choir-like sound, similar to those heard from vintage synthesisers such as the Roland VP330. Last time I used just a standard VCO into VCF setup/synth voice, with modulation to simulate a human, organic sound from the oscillators. This time I'm using the AJH Synth Wave Swarm for this purpose, and the Fixed Filter Bank 914 for tone shaping: The Fixed Filter Bank is more suited to this than a regular VCF, as a single filter will only allow a single frequency range to be added to (or subtracted from) the tone of the sound, whereas the filter bank will allow multiple frequencies to be cherry-picked and boosted based on what is needed to create the final sound.
It's worth also watching the previous video for additional ideas to further build on this sound, including pitch modulation. 'Choir Pad 1' can be found here: [ Ссылка ]

Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
In the video I'm using the Glide + Noise MkII module to access the CV Bus, allowing me to control both VCOs from one input/cable. If you are not able to use the CV Bus you will need to use a multiple or stacking cables to connect the keyboard to each VCO's 1V/Oct input, as is usual with a fully modular synth.
VCO: Sawtooth waves are used here, as they are much closer in timbre to the human voice than the other wave shapes. Setting them at the same octave, or an octave apart produces good results.
Wave Swarm: I've set all the pots at just below 50% as an example, but it's worth experimenting using fewer animators, building them up one by one, or at different levels.
Fixed Filter Bank 914: Don't raise frequency levels too far beyond 50% to avoid feedback, and be mindful that too high an input level can start to distort the incoming signal, which might also be a desirable effect in some cases.
Modules used from top-left to bottom-right: Glide + Noise (optional), Vintage Transistor Core VCO x2, Contour Generators, Wave Swarm, Fixed Filter Bank 914, Discrete Cascaded VCA.
