This stereo analogue filter allows different filter modes for the left and right channels, and then messes with the dimensions of space by applying mid‑side processing afterwards.
This ensemble oscillator comprises 16 sine wave VCOs in one module, each voice of which will play different (related) programmed notes/harmonics in arrays that you can select, tweak and voltage control.
Continua is a three-oscillator, twin-filter analogue-style synthesizer plug‑in for Mac, Windows and iOS, and there's even an experimental Linux build too.
