Antkai released Efta.High VSTi, a free virtual instrument.
You can choose between 32 factory presets (or create your own). In my opinion, this plugin is perfect for 80s dance music (techno, italo-pop etc).
Subtractive Synthesis.
Voice: 6 (poly, legato, mono)
OSC: 2 (4 wave types with mods)
Filter: 2 (and 2 pitch mods)
LFO: 4 (with mods and tempo sync)
Matrix with “inverse” pins.
