VCF: Prophet 5 & Pro-3, Leipzig & Ample, Perfourmer MK II, DFAM, Dominion 1, ARP 2600m...

I recorded a comparison of filters (VCF) working with a square waveform and self-oscillation.
Synths: Sequential Prophet 5 Desktop, Sequential PRO-3, Vermona Perfourmer MK II, Moog DFAM, Analogue Solutions Leipzig, Analogue Solutions Ample, ARP 2600m, Olivella Modular Imagenes (OTA 2-pole).
I did not pursue the goal of showing the maximum resonance. The idea was to see the limits of the filters in the musical plane, the difference in their timbre properties and characteristics in practice.
I also did not pursue the goal of recording the highest possible sound quality, so in some places you can hear distortions and slightly different volumes of the game.
