L-1 DM VCF plays some melodies.

video upload by Aleksei Laman

"L-1 DM VCF from the L-1 Filters Collection.
It's state-variable filter with double cells. It gives 24dB/oct filtration.
Comparing to other filters of the Collection:
This one is most 'ideal' working.
It gives stable equal loudness selfoscillation in full frequency range.
It has thinnest resonance spike, so the resonance sounds not so 'bold' as others.
It sounds sharp and clean. If you want fat and dirty - this is not that one.
It adds less overtones and harmonics to the sound comparing to other filters of the Collection.
Someone can say it's too cilinic and dry, but often this is exactly what is needed."
